What is Colorectal Cancer? Symptoms, Risk Factors & Treatments
What Does Anal Cancer Look Like?
Typically, a person cannot identify anal cancer by sight. However, in some cases, small, hard lumps may develop just inside and outside the anus, so it may be beneficial to learn about what anal cancer may look like.
Usually, a person cannot see anal cancer. However, in some cases, they may have hard, fleshy lumps just inside or outside the anus.
A person may not be able to identify anal cancer externally.
People may also develop a painful sore around the anus that does not heal.
Other associated symptoms
Additional possible symptoms of anal cancer include:
However, approximately 20% of individuals with anal cancer do not experience any symptoms.
In some cases, a person may mistake hemorrhoids for anal cancer, particularly external hemorrhoids. These occur when there is too much pressure on the veins around the anus.
There are two different types of hemorrhoids:
The table below outlines some key differences between hemorrhoids and lumps relating to anal cancer:
Lumps on or around the anus are not always cancer. Below are some possible other causes of lumps on or around the anus.
Polyps
This is a benign growth that may form in the anus. They are often small, bumpy, and mushroom-shaped. Symptoms include blood in the stool, mucus, stomach pain, and a change in bowel habits.
Polyps affect approximately 20–30% of American adults.
Anal warts
Skin tags
Skin tags look similar to hemorrhoids and warts. They are small, skin-colored, and usually soft. These lumps are benign, but doctors can remove them if a person wishes.
Anal fissures
These are small tears in the anal lining. Initially, an anal fissure does not cause lumps. However, if the fissure spreads downward, it can result in a lump.
A person should contact a doctor if they develop lumps around the anus area, particularly if rectal bleeding or changes in bowel habits also accompany them.
People should also contact a doctor if they experience any other symptoms of anal cancer.
How does a person tell the difference between a hemorrhoid and a tumor?Anal cancer and hemorrhoids both present with lumps near the anus, but hemorrhoids may protrude during bowel movements and are softer and more "squishy." Anal cancer growths tend to be irregular in shape. Contact a doctor if there are concerns as to whether a hemorrhoid could be anal cancer.

What are the early signs of anal cancer?Signs of anal cancer include lumps near the anus and bleeding from the rectum.
Signs of anal cancer include lumps near the anus and bleeding from the rectum.
Some individuals with anal cancer may not develop any symptoms. However, occasionally, individuals may be able to feel lumps just inside or outside the anus.
These lumps may also cause rectal bleeding, pain or pressure in the anus, itching, and discharge.
If a person experiences symptoms of anal cancer, they should consult a doctor.
FDA Approves First Advanced Anal Cancer Drug As First-Line Treatment
Zynyz is now FDA-approved as the first and only approved first line treatment for advanced squamous cell carcinoma of the anal canal.
Incyte announced that the FDA has approved Zynyz (retifanlimab-dlwr) as a combination therapy for the treatment of adult patients with inoperable locally recurrent or metastatic squamous cell carcinoma of the anal canal (SCAC) alongside carboplatin and paclitaxel (platinum-based chemotherapy). Zynyz was also approved as a monotherapy for adult patients with locally recurrent or metastatic SCAC or an intolerance to platinum-based chemotherapy, according to a news release published yesterday.
Squamous cell carcinoma of the anal canal is the most common type of anal cancer, making up 85% of cases today. Although anal cancer only accounts for less than 1% of all cancers, incidence is increasing approximately 3% every year. Most (90%) of cases are associated with human papillomavirus (HPV) infection.
Zynyz is a humanized monoclonal antibody that targets the programmed death receptor-1 (PD-1), mimicking the immune system's ability to fight pathogens, like HPV.
Risk factors for anal cancer include having a compromised immune system from HIV or autoimmune disease.
Anal cancer symptoms can include anal or rectal discharge, a lump near the anus or pain and itching near the anus.
The recommended dosage of Zynyz for both indications is a 500mg intravenous infusion given over 30 minutes every four weeks until disease progression, according to the prescribing information. Zynyz as combination therapy can be given for up to 12 months and Zynyz as monotherapy can be given for up to 24 months.
Combination therapy approval was based on the results of the POD1UM-303/InterAACT2 study and of 308 patients given either Zynyz or placebo and chemotherapy. Patients treated with Zynyz showed a 37% reduction in the risk of progression or death compared with placebo.
Patients treated with both Zynyz and chemotherapy had an average of 9 months of progression-free survival, compared with placebo, which resulted in an average of 7 months of progression-free survival.
Adverse reactions occurred in 47% of patients, including sepsis (3%), pulmonary embolism (3%) and diarrhea (2%).
The monotherapy approval indication is based on the results of the POD1UM-202 study. Patients treated with Zynyz had an objective response rate of 14% and a disease control rate of 49%.
Adverse reactions occurred in 40% of patients, the most common being urinary tract infections, perineal pain and abdominal pain, all occurring in at least 2% of patients.
"Patients with inoperable locally recurrent or metastatic anal cancer have historically faced poor five-year survival rates and limited treatment options," Marwan Fakih, M.D., professor of medical oncology & therapeutics research, associate director of clinical sciences and medical director, Briskin Center for Clinical Research, division chief, GI medical oncology, and co-director, gastrointestinal cancer program, City of Hope, said in the news release. "The POD1UM data highlight the potential of Zynyz to be a meaningful new option and notably demonstrate that the addition of Zynyz to platinum-based chemotherapy significantly improves progression-free survival."
Eligible patients can visit IncyteCARES for financial support and ongoing education. Patients may pay as little as $15 out of pocket for their prescription if they are a commercially insured resident of the United States or Puerto Rico.
Zynyz is also FDA approved to treat adult patients with metastatic or recurrent locally advanced Merkel cell carcinoma.
Haemorrhoids Or Anal Cancer: How To Tell The Difference Between Symptoms
A lot of the symptoms and signs associated with stomach-related conditions are overlapping in nature, often leading to confusion and delay in diagnosis. For instance, bloating and abdominal pain can occur due to acid reflux as well as Irritable Bowel Syndrome (IBS). Similarly, haemorrhoids and anal cancer can both present with lumps or growths near the anus, but the two are completely different illnesses.
In an interaction with the OnlyMyHealth team, Dr Amit Upadhyay, Senior Consultant, Oncology and Haematologist at PSRI Hospital, Delhi, highlights the differences between the two conditions and shares ways to reduce the risk through lifestyle changes. He also lists tests that can help diagnose or rule out the two conditions accurately.

How To Differentiate Between Haemorrhoid And Anal Cancer Growths?From lumps or growths near the anus to rectal bleeding and itching, both haemorrhoids and anal cancer can cause similar symptoms. However, haemorrhoids are significantly more common than anal cancer. As per a study published in the journal Cureus, around 50-85% of people suffer from haemorrhoids worldwide. On the other hand, anal cancer is not very common, with over 50,000 new cases reported in 2020, according to a study published in the European Journal of Cancer Prevention.
Dr Upadhyay notes that both haemorrhoids and anal cancer can cause rectal bleeding, but the nature of the bleeding differs. "Haemorrhoids typically present with bright red blood, indicating fresh bleeding. In contrast, dark reddish or altered blood is more commonly associated with anal cancer," he differentiates.
Other symptoms that may suggest anal cancer rather than haemorrhoids include the presence of a growth near the rectal area, persistent pain in the anal region, unusual rectal discharge, changes in bowel habits, such as alternating constipation and diarrhoea, and unexplained weight loss, which is a strong indicator of anal cancer.
On the other hand, haemorrhoids are often linked to chronic constipation and do not typically cause weight loss, the doctor further explains.
Understanding The Growths Associated With Haemorrhoid And Anal CancerA lump or tiny growths near the anal region may be alarming. While lumps associated with haemorrhoids occur due to increased pressure in the veins around the anus and lower rectum, anal cancer growths are primarily linked to infection with the Human Papillomavirus (HPV), a Sexually Transmitted Infection (STI).
"Haemorrhoids are generally classified as internal or external. External haemorrhoids appear as soft, bluish swellings around the anus. These are venous prominences that may remain outside or temporarily protrude during bowel movements. Internal haemorrhoids are located inside the rectum and may not be visible but can cause bleeding and discomfort," explains Dr Upadhyay.
"In contrast, anal cancer growths are usually hard, fixed, and non-mobile. They may or may not be tender but tend to remain firm and immovable, unlike haemorrhoids, which are soft and can sometimes retract inside," he adds.

When To Seek Medical Attention?Any rectal bleeding, regardless of the cause, should not be ignored, emphasises Dr Upadyay, adding, "If bleeding persists for more than 2-3 weeks, especially if accompanied by fever and weight loss, it is essential to seek medical attention."
According to him, persistent rectal bleeding may indicate not only haemorrhoids but also anal fissures, infections, or rectal cancer. If there is any uncertainty, a professional evaluation is necessary to rule out serious conditions.
Diagnostic Tests To Confirm What It IsTo determine whether a rectal growth is a haemorrhoid or cancerous, doctors use diagnostic tests such as:
Certain lifestyle modifications can lower the risk of both haemorrhoids and anal cancer:
Haemorrhoids and anal cancer can lead to overlapping symptoms, but the two conditions are completely different. It is extremely crucial to distinguish between the two conditions so as to avoid delay in diagnosis and receive proper treatment. So, if you have rectal bleeding, tiny growths near the anus, or persistent itching, consult a doctor/gastroenterologist at the earliest.
