Common skin cancer can signal increased risk of other cancers
A Complete Guide To Screening And Diagnosis For Bladder Cancer
Tests to check for bladder cancer include physical exams, urine tests, and imaging. Biopsy or cystoscopy may help confirm a diagnosis. If you're at high risk, at-home tests might help you screen for bladder cancer.
The bladder is a hollow organ in your lower pelvis. Its job is to store urine until you're ready to release it. When cells in your bladder multiply and grow out of control, bladder cancer may result.
If you have bladder cancer symptoms, a healthcare professional may recommend several diagnostic tests. These tests may rule out bladder cancer. If you have bladder cancer, diagnostic testing can identify your type and stage.
For some cancers, doctors recommend screening every year or every several years. They may suggest you get screened for cancer even if you're at average risk or have no symptoms. You may be familiar with screenings such as mammograms for breast cancer and colonoscopy for colon cancer.
Unlike these cancers, there's no standard or routine screening test for bladder cancer. But if you're at a higher risk of this condition or have had bladder cancer in the past, a doctor will recommend routine screenings, even if you don't have any symptoms.
Bladder cancer symptoms include:
Blood in your urine is the most common bladder cancer symptom. If you have hematuria or any other bladder cancer symptoms, a clinician will look for additional signs of this condition.
If the disease has advanced, a physical exam may identify the following symptoms:
A clinician may also do a bimanual (two-handed) exam to look for a mass (tumor) in your abdomen, pelvis, or rectum.
For those with a vagina, clinicians may perform a pelvic exam to look for masses in the vaginal wall. For those with a prostate, they may perform a rectal exam and check the lower abdomen for masses in the prostate.
If you previously had bladder cancer, a healthcare professional will recommend routine screening that includes urine tests. If your cancer has come back, a screening test may identify it early, when treatment can work best.
Doctors can also use urine tests to diagnose bladder cancer. However, these don't provide enough information on their own to allow for a diagnosis. In some cases, a urine test can miss cancer or produce a false positive.
Urine tests require you to supply a urine sample by peeing into a sterile cup. If you feel dehydrated, you may need to drink fluids before you give a sample. This noninvasive test requires no preparation other than washing your hands. You'll usually go to a healthcare clinic to provide the sample.
Urinalysis (hematuria test)
Urinalysis tests for bladder cancer can identify red blood cells in your urine. A urinalysis can also find white blood cells and other substances, such as bacteria. Doctors also use urinalysis to help diagnose other conditions, such as diabetes or urinary tract infections (UTIs).
Blood in your urine is the most common symptom of bladder cancer. In some instances, blood may visibly change the color of your urine to pink, brown, or red. When you can see the blood in your urine, doctors refer to it as gross hematuria ("gross" meaning "large").
Blood in the urine isn't always visible to the eye. Sometimes, it can only be visible under a microscope. This is called microscopic hematuria.
For this test, you'll supply a urine sample that a doctor will send to a laboratory for analysis. As a first step, a clinician may also use an in-office dipstick to check for blood in your urine. Dipstick tests sometimes result in false positives, so doctors depend on lab tests that use a microscope to back them up.
Various conditions can cause blood in your urine. A urinalysis can detect blood but won't provide enough information to definitively diagnose bladder cancer.
Urine cytology
A urine cytology test looks for cancerous and precancerous (abnormal) cells in your urine. Your sample will be sent to a lab and viewed under a microscope. Lab technicians will analyze the sample for the presence of tumor cells.
Urine culture test
Urine culture tests identify fungi, yeasts, and bacteria that cause infection. They don't identify bladder cancer. A clinician may recommend this test to rule out other diagnoses, such as a UTI.
Urine tumor marker test
Urine marker tests look for substances in your urine that might indicate bladder cancer. There are several types. The American Cancer Society lists these urine tumor marker tests for bladder cancer:
There are tests you can take at home to check for bladder cancer. However, experts don't recommend these as the only diagnostic tool. They also don't recommend them for people who don't have a history of bladder cancer.
If you're checking for bladder cancer recurrence, a healthcare professional may recommend using at-home urine tests that measure biomarker genes. After you take a urine sample at home, you mail it back to a laboratory for analysis.
At-home tests provide convenience and may limit your need for invasive testing. Some health insurance providers, including Medicare, may cover some of these tests.
Cystoscopy is a minimally invasive procedure that lets a doctor see inside your bladder and urethra. Unlike scans, which may miss certain spots, cystoscopes provide a complete view of the bladder. Some doctors may use cystoscopy as a screening tool.
Cystoscopy is usually an outpatient procedure. You'll also be under local or general anesthesia. A healthcare professional will give you complete instructions about the type and scope of procedure you're expected to have.
A clinician will insert the cystoscope (a thin tube with a lit end) into your urethra and thread it through to your bladder. They'll insert water or a sterile saline solution into the cystoscope to expand the bladder wall. This makes it easier to view the bladder's inner lining, where most bladder cancers start.
There are two types of cystoscopes. A flexible cystoscope can only help view the inside of your bladder and urethra. It's very narrow and bendy. You can usually be awake for the procedure.
A rigid cystoscope is slightly wider and doesn't bend. However, a clinician can insert surgical instruments into it. They can use these tools to remove cysts, benign growths, small tumors, or tissue samples for biopsy.
Either type is an option, no matter your sex.
Male cystoscopy
In those with a penis, the urethra forms a bridge between the bladder and the penis. Your body transports urine, semen, and sperm out of your body through your urethra.
The opening of the urethra (urethral meatus) is located at the tip of the penis. During a cystoscopy, a healthcare professional will place the scope into the urethra through this opening.
Female cystoscopy
In those with a vagina, your urethra transports urine out of the body. It's located at the foot of your bladder and extends down through your pelvic floor. The opening of the urethra is located within the labia minora, in front of the vaginal opening.
If you need a cystoscopy, a healthcare professional will place the scope into your urethra through the urethral opening.
In some instances, a doctor may find suspicious or abnormal-looking tissue during a cystoscopy. If so, they may perform a biopsy to determine if these areas of tissue contain cancer cells.
A biopsy is a laboratory test that analyzes tissues taken from the body under a microscope. It can help a doctor make a definitive diagnosis of bladder cancer, determine the tumor grade, and determine the amount of spread, or invasiveness, within the bladder wall.
If a doctor uses a rigid cystoscope during a cystoscopy, they may remove a tiny piece of tissue for testing.
They may also choose to do a follow-up surgical procedure called transurethral resection of bladder tumor (TURBT). Doctors use TURBT to confirm a bladder cancer diagnosis and to check for tumor spread into the muscle layer of the bladder wall.
During a TURBT procedure, a doctor will remove any tumors they find for biopsy. They'll also remove a portion of the bladder muscle surrounding the tumors and send it to a lab for analysis.
Since cancer cells spread before tumors form, a doctor may also remove tiny portions of tissue from throughout the bladder for testing. They may also use a saltwater wash during a TURBT procedure. They can check the collected water for cancer cells in the lab.
Since blood in urine is often visible, doctors catch many cases of bladder cancer early. But in some instances, cancerous cells may have a chance to spread outside your bladder. Doctors can use imaging tests after a diagnosis to check for enlarged lymph nodes and tumors in tissues and organs throughout the body.
Imaging can also provide information about the primary (original) tumor. Imaging tests for bladder cancer include:
Computed tomography (CT) urogram
CT scans use X-rays to obtain cross-sectional images of your body. CT urograms are scans that look at your ureters, bladder, kidneys, and nearby lymph nodes. A CT urogram provides information about a bladder cancer tumor's size, shape, and position.
Magnetic resonance imaging (MRI) urogram
Unlike CT scans, MRIs use magnets and radio waves instead of X-rays to take pictures. MRI urograms involve images of the upper urinary system. Doctors also use MRI scans to identify areas of localized spread outside your bladder.
Intravenous pyelogram (intravenous urogram)
An intravenous (IV) pyelogram uses X-rays to take pictures of your urinary system. For this test, a clinician will inject X-ray dye into a vein. The dye highlights urinary tract tumors, making them easier to see.
Retrograde pyelogram
If you're unable to get an injection into a vein, a doctor may recommend a retrograde pyelogram instead. These tests are less common. For this test, they'll inject the X-ray dye through a catheter they place in your urethra.
Ultrasound
Ultrasounds take pictures of your internal organs with sound waves. Doctors can use a bladder ultrasound to gauge the size of bladder cancer tumors and to check for spread in nearby organs, such as your kidneys.
Bone scan
If you have bone pain or tenderness, a doctor may perform a bone scan to check for bladder cancer spread into your bones. For this test, they'll inject low-level radioactive material into one of your veins. They'll then use a camera to create an image of your skeleton showing areas where the material indicates the presence of cancer cells.
Chest X-ray
A doctor may perform a chest X-ray to determine if cancer has spread to your lungs.
Bladder Cancer Symptoms You Should Never Ignore
Medical experts reveal the essential warning signs that could save your life if caught early
Bladder cancer affects approximately 83,000 Americans each year, yet remains one of the most overlooked forms of cancer despite having excellent survival rates when caught early. This disconnect between treatability and awareness has medical professionals increasingly concerned about delayed diagnoses that allow the disease to progress unnecessarily.
"The problem isn't that bladder cancer is particularly difficult to treat in its early stages," explains one leading urological oncologist. "It's that patients often dismiss the early warning signs or attribute them to more common conditions, losing valuable time before seeking medical attention."
While bladder cancer predominantly affects older adults, with the average age at diagnosis being 73, younger individuals aren't immune. Smoking remains the leading risk factor, contributing to about half of all cases, but environmental exposures and genetic factors play significant roles as well. This complex interplay of risk factors makes symptom awareness crucial for everyone, regardless of age or lifestyle.
The good news is that when detected at the earliest stage, the five-year survival rate for bladder cancer exceeds 95%. Even better, many of the warning signs are distinctive enough to prompt medical investigation if people know what to watch for. Understanding these critical symptoms could literally save your life or the life of someone you love.
The overlooked complexities of bladder cancerBladder cancer comes in several forms, each with distinct characteristics and treatment challenges. Urothelial carcinoma (formerly called transitional cell carcinoma) accounts for about 90% of cases and begins in the cells lining the inside of the bladder. Less common types include squamous cell carcinoma and adenocarcinoma, which typically develop after years of infection or irritation.
The bladder's function as a reservoir for storing urine makes it particularly vulnerable to cancer-causing agents. As urine concentrates in the bladder, carcinogens that have entered the bloodstream can remain in contact with the bladder lining for hours, potentially damaging cellular DNA and initiating cancerous changes.
This cancer typically begins in the innermost layer of the bladder wall but can grow deeper into surrounding tissues over time. As it progresses through these layers, treatment becomes more complex, highlighting why early detection through symptom recognition is so vital.
What makes bladder cancer particularly concerning is its high recurrence rate. Even after successful treatment, there's approximately a 50-80% chance of recurrence within five years for non-muscle invasive bladder cancer, requiring lifelong surveillance. This persistent nature underscores why catching the disease at its earliest, most treatable stage is crucial.
1. Blood in urine – the most important warning signBlood in the urine, medically known as hematuria, is the most common and significant symptom of bladder cancer, occurring in approximately 80-90% of cases. What makes this symptom particularly important is that it often appears early in the disease's progression, providing a valuable opportunity for detection.
The blood may be visible, turning urine pink, red, or cola-colored, but it can also be microscopic, detectable only through laboratory testing. This microscopic hematuria is often discovered incidentally during routine urinalysis, emphasizing the value of regular check-ups.
What makes hematuria particularly concerning as a cancer symptom is that it typically occurs without pain. While kidney stones and urinary tract infections also cause bloody urine, they usually produce additional symptoms like discomfort or burning sensations. Painless bleeding should therefore always prompt medical evaluation.
The intermittent nature of this symptom often leads people to delay seeking medical attention, especially if the bleeding stops quickly. However, even a single episode of bloody urine warrants investigation, particularly in individuals over 50 or those with risk factors such as smoking history or chemical exposure.
Medical evaluation for hematuria typically includes a thorough urinalysis, imaging studies like CT urography, and often cystoscopy, a procedure that allows direct visualization of the bladder interior. These tests can distinguish between various potential causes and identify concerning lesions requiring further investigation.
2. Changes in urination patterns that signal dangerAlterations in urination habits represent another critical warning sign of potential bladder cancer. These changes typically manifest as increased frequency, sudden urgency, or difficulty initiating urination, all of which result from the tumor's physical presence disrupting normal bladder function.
Frequent urination, especially when it develops suddenly without explanation, warrants attention. While many conditions from diabetes to overactive bladder can increase urination frequency, persistent changes without other clear cause deserve medical evaluation, particularly when accompanied by other symptoms on this list.
Urgency—the sudden, compelling need to urinate that's difficult to postpone—occurs as the tumor irritates the bladder lining or interferes with the organ's normal capacity. This symptom can significantly impact quality of life, causing anxiety about bathroom accessibility and disrupting sleep patterns.
Difficulty starting urination or maintaining a steady stream may indicate that a tumor is blocking the bladder outlet or affecting the muscles controlling urination. This symptom becomes particularly concerning when it develops progressively over weeks or months rather than appearing suddenly.
What distinguishes cancer-related urinary changes from more common conditions like urinary tract infections is their persistence. While infections typically resolve with antibiotics within a week, symptoms related to bladder cancer persist or worsen over time. Any urinary changes lasting longer than two weeks warrant medical attention.
Importantly, these symptoms often overlap with benign prostatic hyperplasia (BPH) in men and overactive bladder in women, leading to potential misdiagnosis. Thorough evaluation by a healthcare provider can differentiate between these conditions and identify cases requiring further investigation for cancer.
3. Pelvic discomfort and pain signals that shouldn't be dismissedPain in the pelvic region, while less common in early-stage bladder cancer, becomes increasingly prevalent as the disease advances. This discomfort typically manifests as pressure, pain, or tenderness in the lower abdomen and can vary from mild and intermittent to severe and constant.
The location of pain often provides clues about the cancer's progression. Pain concentrated on one side of the lower abdomen might indicate that the cancer has grown through the bladder wall and is affecting nearby tissues. More diffuse pain throughout the pelvis could suggest more extensive spread.
What distinguishes cancer-related pelvic pain from other causes is its persistent nature and gradual worsening over time. Unlike the sudden onset of pain associated with kidney stones or the cyclical pain of menstrual cramps, cancer pain typically follows a progressive pattern without complete resolution.
For some patients, pain occurs specifically during urination (dysuria), creating a burning sensation similar to a urinary tract infection. When this symptom persists despite antibiotic treatment or recurs frequently, it requires further investigation to rule out bladder cancer.
Back pain, particularly in the lower back, can also signal advanced bladder cancer that has spread to nearby lymph nodes or bones. This symptom easily masquerades as ordinary back pain or strain, making it important to consider bladder cancer when back pain coincides with other urinary symptoms.
Any unexplained pelvic pain lasting more than two weeks deserves medical attention, especially for individuals with risk factors for bladder cancer. Diagnostic imaging such as CT scans or MRIs can help identify whether such pain stems from bladder abnormalities or other pelvic conditions.
4. Unexplained weight loss and systemic symptomsSignificant, unintentional weight loss—typically defined as losing 5% or more of body weight within 6-12 months without trying—represents a serious symptom that may indicate bladder cancer has advanced beyond its initial site. This weight loss occurs as cancer cells consume energy and alter the body's metabolism.
What makes this symptom particularly concerning is that it typically doesn't appear until the cancer has reached a more advanced stage or spread to other parts of the body. When weight loss occurs alongside urinary symptoms, it significantly raises the level of concern and the urgency for comprehensive evaluation.
Fatigue that persists regardless of adequate rest often accompanies unexplained weight loss in cancer patients. This profound tiredness results from the body's inflammatory response to cancer and the energy demands of fighting the disease. When everyday activities become exhausting without clear reason, medical evaluation becomes essential.
Loss of appetite frequently precedes noticeable weight loss and merits attention, particularly when it persists for more than two weeks. Cancer can affect appetite through direct effects on metabolism, by producing substances that suppress hunger, or by causing discomfort that makes eating less appealing.
These systemic symptoms rarely occur in isolation with bladder cancer. They typically develop alongside the urinary symptoms described earlier, creating a constellation of changes that should prompt immediate medical attention. The combination of urinary changes and unexplained weight loss represents a particularly urgent situation requiring comprehensive evaluation.
For older adults especially, there's a tendency to attribute weight loss and fatigue to aging rather than potential disease. This misconception can delay diagnosis significantly. Healthcare providers should consider bladder cancer in their differential diagnosis when these symptoms appear, particularly in patients with risk factors like smoking history or relevant occupational exposures.
5. Lower extremity swelling that indicates progressionSwelling in the legs, ankles, and feet—medically termed lower extremity edema—can signal that bladder cancer has advanced to a stage where it's affecting the lymphatic system or causing vascular compression. This symptom typically doesn't appear until later stages of the disease, making it a critical indicator of progression.
The mechanism behind this swelling involves cancer cells spreading to lymph nodes in the pelvis and abdomen, blocking the normal flow of lymphatic fluid from the legs back toward the heart. As this fluid accumulates in the lower extremities, visible swelling results, often beginning around the ankles and progressing upward.
What distinguishes cancer-related edema from more common causes like heart failure or venous insufficiency is that it typically affects both legs similarly and may be accompanied by other symptoms of bladder cancer. The swelling usually develops gradually over weeks rather than appearing suddenly.
Another concerning feature is that cancer-related leg swelling often doesn't improve significantly with elevation or overnight rest, unlike edema from many other causes. This persistence, especially when accompanied by urinary symptoms, should trigger prompt medical evaluation.
In advanced cases, the swelling may extend to the genitals or lower abdomen as lymphatic blockage becomes more extensive. This progression represents a medical urgency requiring immediate attention, as it indicates significant disease advancement and potential complications.
Diagnostic imaging, particularly CT scans with contrast or specialized lymphatic imaging, can identify whether such swelling stems from cancer-related lymphatic obstruction. Early intervention for this symptom can prevent complications and improve quality of life, even in advanced disease.
6. Complete bladder emptying difficultiesThe inability to completely empty the bladder, a condition called urinary retention, develops in some bladder cancer patients as tumors grow and interfere with normal bladder function. This symptom manifests as a persistent sensation that the bladder isn't fully empty, even immediately after urination.
Incomplete emptying creates a cascade of problems beyond discomfort. Residual urine provides an ideal environment for bacterial growth, increasing infection risk. These infections can mask underlying cancer by temporarily explaining away symptoms like frequency and urgency that are actually tumor-related.
What distinguishes cancer-related retention from other causes like prostate enlargement is its progressive nature and association with other bladder cancer symptoms. While prostate issues typically develop gradually over years, cancer-related changes often progress more rapidly over months.
For some patients, this retention eventually leads to the paradoxical symptom of overflow incontinence—involuntary urine leakage occurring when the bladder becomes overfilled. This seemingly contradictory combination of retention and leakage represents a serious situation requiring prompt medical evaluation.
Urologists can measure post-void residual urine volume using ultrasound or catheterization to objectively assess retention severity. Significant residual volumes that develop without other clear explanation warrant thorough investigation, including potential evaluation for bladder cancer.
Early intervention for this symptom is crucial not only for cancer detection but also to prevent kidney damage. When urine backs up into the kidneys due to chronic retention, it can compromise kidney function over time, creating additional health complications beyond the primary cancer concern.
7. Recurrent urinary tract infections in adultsFrequent urinary tract infections (UTIs) in adults, particularly when they recur despite appropriate antibiotic treatment, can sometimes indicate underlying bladder cancer. Tumors create surface irregularities in the bladder lining that harbor bacteria, making infections more likely and more difficult to completely eradicate.
What makes this symptom particularly concerning is how easily it leads to diagnostic delays. Both patients and clinicians often attribute recurrent urinary symptoms entirely to infection without investigating potential underlying causes, especially after bacterial culture confirms infection presence.
The clinical pattern that should raise suspicion includes: Three or more UTIs within a 12-month period; Infections that recur shortly after completing appropriate antibiotic therapy; UTIs accompanied by blood in the urine, particularly after the infection appears resolved and; infections that consistently involve the same unusual bacterial strains
Adults without typical UTI risk factors deserve particular attention when experiencing recurrent infections. While frequent UTIs might be expected in individuals with certain anatomical variations, diabetes, or immune compromise, they warrant thorough investigation in otherwise healthy adults, particularly smokers.
Medical evaluation should extend beyond treating the immediate infection to include imaging studies and potentially cystoscopy, especially for patients over 50 or those with significant risk factors for bladder cancer. This comprehensive approach can identify underlying tumors that might otherwise remain undetected for months or years.
When to seek medical attentionAny symptom from this list warrants prompt medical evaluation, but certain situations require particularly urgent attention. These include visible blood in the urine, significant unexplained weight loss combined with urinary symptoms, or new swelling in the legs when accompanied by other symptoms described here.
The appropriate starting point for evaluation is typically a primary care provider who can conduct initial assessment and refer to specialists as needed. Patients should prepare for appointments by documenting when symptoms began, their frequency and severity, and any factors that seem to worsen or improve them.
During evaluation, healthcare providers typically begin with a thorough history and physical examination, followed by urinalysis to check for blood, infection, and abnormal cells. Further testing often includes imaging studies like ultrasound or CT scans and may progress to cystoscopy for direct bladder visualization.
Patients should not delay seeking care due to embarrassment about urinary symptoms or fear of potential diagnosis. The significant improvement in survival rates with early detection makes prompt evaluation the most effective approach for achieving positive outcomes.
Risk factors worth knowingUnderstanding personal risk factors can help contextualize symptoms and inform discussions with healthcare providers. While presence of symptoms is always more important than risk factors alone in determining the need for evaluation, certain individuals should maintain particularly high vigilance.
Tobacco exposure represents the most significant modifiable risk factor, with smokers experiencing triple the bladder cancer risk of non-smokers. This risk decreases gradually after quitting but never returns completely to baseline, making symptom awareness particularly important for current and former smokers.
Occupational exposures pose substantial risks for specific professions. Workers in the dye, rubber, leather, printing, paint, and truck driving industries face elevated bladder cancer rates due to exposure to aromatic amines and other carcinogens. These individuals should report even mild urinary symptoms promptly.
Age significantly influences risk, with most cases diagnosed after age 55. However, bladder cancer can occur at any age, and younger patients often experience longer diagnostic delays because the condition isn't initially considered. Urinary symptoms deserve thorough evaluation regardless of age.
Family history matters as well, with first-degree relatives of bladder cancer patients experiencing roughly twice the average risk. This genetic component makes symptom awareness particularly important for those with family history, even without other obvious risk factors.
Chronic bladder inflammation from conditions like recurrent UTIs, kidney stones, bladder stones, or indwelling catheters increases cancer risk over time. Individuals with these conditions should maintain vigilant monitoring for changes in their typical symptoms that might indicate cancer development.
Prevention strategies that workWhile symptom awareness remains crucial, certain preventive strategies can reduce bladder cancer risk or improve outcomes through earlier detection. These approaches deserve consideration, particularly for those with elevated risk based on factors discussed above.
Smoking cessation represents the single most effective preventive measure. Quitting reduces risk beginning immediately and continuing to improve over time, though some elevated risk persists for years. Support resources like counseling, medications, and nicotine replacement therapy can improve success rates.
Hydration plays an important protective role by diluting potential carcinogens and reducing their contact time with bladder tissues. Drinking water frequently throughout the day helps maintain optimal bladder health and may reduce cancer risk, particularly for those with occupational exposures.
Workplace safety measures including proper ventilation, protective equipment, and adherence to exposure guidelines help reduce occupational risks. Workers should advocate for appropriate protections and utilize all available safety equipment consistently.
Diet may influence risk as well, with evidence suggesting that abundant fruit and vegetable consumption provides protective effects. Antioxidants in these foods help neutralize free radicals that can damage cellular DNA, potentially preventing cancer-initiating mutations.
Regular medical check-ups with urinalysis can detect microscopic blood and other abnormalities before symptoms develop. Those with risk factors should discuss appropriate screening intervals with their healthcare providers rather than waiting for symptoms to appear.
By combining vigilant symptom awareness with these preventive approaches, individuals can significantly reduce their bladder cancer risk and improve their chances of early detection if cancer does develop. This proactive approach represents the best strategy for addressing this common but often overlooked form of cancer.
