Prostate cancer: How you sleep may increase risk of developing the deadly disease - Express

-

Prostate cancer affects around one in eight men in the UK, but tends to be more common in men over the age of 65. Because there’s currently no cure for cancer, understanding what could potentially cause it can help prevent it.

Doctors don’t yet known the exact reasons why some men develop prostate cancer, but a number of risk factors have been associated with the disease.

Bupa explains: “Prostate cancer can run in families. Certain genes, such as one called BRCA2, can put people at higher risk.

“So, if you have a close relative with prostate cancer, such as a brother or father, you’re more likely to develop it.

“Men who eat a lot of high-fat foods may be more likely to develop prostate cancer too.

“You’re also more likely to develop prostate cancer if you’re black or over 50.”

Recent studies have suggested links between sleep and prostate cancer risk, with one study associating sleep problems with an increased risk for men developing the disease.

Study author Dr Lara Sigurdardottir, of the University of Iceland in Reykjavik said: “Prostate cancer is one of the leading public health concerns for men, and sleep problems are quite common.

“If our results are confirmed with further studies, sleep may become a potential target for intervention to reduce the risk for prostate cancer.”

The study involved around 2,100 men, aged 67 to 96, in Iceland, and the participants were asked if they took medications to help them sleep, had trouble falling asleep or woke up during nights or early in the morning and had difficulty going back to sleep.

The researchers found 14.4 percent of the men had severe or very severe sleep problems.

While none of the men had prostate cancer at the start of the study, during five years of follow-up, 6.4 percent were diagnosed with prostate cancer, according to the study which was published in the journal Cancer Epidemiology, Biomarkers & Prevention.

After adjusting for age, the researchers concluded men with sleep problems were 1.6 to 2.1 times more likely to develop prostate cancer than those without sleep problems.

cancer lump on neck :: Article Creator Doctor Watching TV Show Spotted Cancer On Show's Guest That She Didn't Know About Say what you will about social media and daytime TV, but sometimes, they can help work wonders. In fact, the power of Facebook and the popularity of HGTV's Beachfront Bargain Hunt played a big part in helping Nicole McGuiness get ahead of her serious cancer diagnosis - but it was an eagle-eyed doctor who really saved her bacon. The then-32-year-old appeared on the property series alongside her father while in search of a holiday home in North Carolina to celebrate her recent recovery from brain cancer in May 2018. She explained that she had set her sights on 'something near the water', specifically a beachfront property in Morehead City, to start afresh in this new phase of her life. Dr. Erich Voigt was one of the viewers who tuned into the Beachfront Bargain Hunt episode, which Nicole featured in, an...

Alan Bryce, MD PARP inhibition with olaparib (Lynparza) improved radiographic progression-free survival (rPFS) in heavily pretreated patients with metastatic castration-resistant prostate cancer (mCRPC) who had alterations in homologous recombination repair (HRR) genes, according to findings from the phase III PROfound trial presented at the 2019 ESMO Congress. This was the first positive randomized phase III trial reported evaluating a PARP inhibitor in men with mCRPC. The PROfound trial enrolled patients to 2 cohorts. In cohort A, 245 patients with  BRCA1/2  or  ATM  alterations, markers of HRR, were randomized 2:1 to receive either olaparib (n = 162) or physician’s choice of abiraterone acetate (Zytiga) with prednisone or enzalutamide (Xtandi) (n = 83). In cohort B, 142 patients with alterations in the  BARD1, BRIP1, CDK12, CHEK1/2, FANCL, PALB2, PPP2R2A, RAD51B/C/D , or  RAD54L , all of which are associated with HRR indirectly, were also randomized 2:...
