Vasectomy, prostate cancer link still uncertain

Although a long-term study has shown that men who had a vasectomy have a slightly increased risk of developed high-grade prostate cancer, not all experts believe that the link is real.

Are testosterone supplements linked to cardiovascular problems?

A growing number of aging men are trying to hold on to their youthful vigor by taking testosterone. Unsettling study results suggest that men with low but “normal” testosterone levels who take a testosterone supplement may be increasing their risk of having a heart attack, stroke, or developing heart disease.

Hormone therapy plus chemotherapy may boost survival in men with advanced prostate cancer

Combining a chemotherapy drug called docetaxel with hormone therapy (androgen-deprivation therapy) to treat advanced prostate cancer appears to work better than starting with hormone therapy and adding docetaxel later.

Low vitamin D tied to aggressive prostate cancer

Prostate cancer tends to be more aggressive in men with low levels of vitamin D. Among African American men, low vitamin D is also linked to a higher risk of developing prostate cancer.

Study: Men with BRCA gene variant should have PSA tests

A study published in the journal European Urology suggests that men who have defects in a cancer-suppressing gene known as BRCA are at high risk for aggressive prostate tumors, and so could benefit from PSA testing.

FDA panel rejects high intensity focused ultrasound for early prostate cancer

An FDA advisory panel rejected a French company’s application to market high intensity focused ultrasound as a treatment for localized prostate cancer.

Hormone therapy does not improve survival for men with localized prostate cancer

In men with cancer that has spread beyond the prostate gland, radiation therapy plus hormone therapy can ease symptoms and improve survival. But some doctors give hormone therapy by itself to millions of men with localized tumors that haven’t spread beyond the prostate. A new study shows that this approach doesn’t help, and may hurt.

Trained dogs can sniff out prostate cancer

With their ability to smell tiny amounts of chemicals, trained dogs can easily find explosives or illegal drugs hidden in a suitcase. But mounting evidence points to another helpful job for man’s best friend: finding prostate cancer before it causes any symptoms.

Delaying treatment for PSA-only relapse poses won’t hurt survival in some men

Men who experience a spike in PSA but who have no symptoms after surgery or radiation therapy for prostate cancer can wait for up to two years before starting hormone therapy, according to a new study.

Erectile dysfunction drugs may protect against penis shrinkage after prostate surgery

Some men have a slightly shorter penis after undergoing surgery to remove a cancerous prostate gland. A new study shows that taking an erectile dysfunction drug like Viagra or Cialis after surgery can prevent that from happening.
