Prostate cancer risk in African Americans

Published November 3, 2009

African American men have, by far, the highest incidence of prostate cancer in the world. They are also more than twice as likely to die of the disease as white American men. No single factor — diet, obesity, socioeconomic status, or biology — accounts for the disparity, and the search for an explanation continues.

What is a “PSA bounce?”

Published September 29, 2009

I had brachytherapy to treat my prostate cancer and my PSA had dropped to 0.3 ng/ml. But six months ago, my PSA had gone up to 0.5, and now it’s up to 0.8 ng/ml. I’m worried that the cancer is back; my doctor said it could be a “PSA bounce.” What’s that?

Can a vasectomy increase prostate cancer risk?

What’s the downside to a biopsy?

Published September 29, 2009

Yes. Even if a man doesn’t ejaculate, sexually transmitted diseases (STDs) can still be passed from one partner to another during sexual activity.

Experimental therapies for prostate cancer

Published September 29, 2009

Androgen deprivation, whether through surgical removal of the testicles or with medication, is an effective treatment for recurring prostate cancer — at least for a while. An improved understanding of the biology of prostate cancer has led to the development of two drugs that might slow disease progression in prostate cancer patients whose disease no longer responds to androgen deprivation.

Stress and benign prostatic hyperplasia (BPH)

Published September 29, 2009

Some evidence suggests that stress reduction may ease symptoms of an enlarged prostate.

Can radiation therapy combat a rising PSA after surgery?
