Treatments for prostate cancer are always evolving, and now research is pointing to new ways of treating a cancer that has just begun to spread, or metastasize, after initial surgery or radiation. Doctors usually give hormonal therapies in these cases to block testosterone, which is a hormone that makes the cancer grow faster. But newer […]

Prostate cancer therapies are improving over time. But how do the long-term side effects from the various options available today compare? Results from a newly published study are providing some valuable insights. Investigators at Vanderbilt University and the University of Texas MD Anderson Cancer Center spent five years tracking the sexual, bowel, urinary, and hormonal […]

Last year, we reported on two studies showing that African American men respond at least as well as white men to prostate cancer treatments given in clinical trials. Nationally, African Americans with prostate cancer are more than twice as likely to die of the disease as their white counterparts, and that has fueled speculation that […]

Prostate cancer screening with the prostate-specific antigen (PSA) test has been criticized for flagging too many slow-growing tumors that might never be life-threatening. But some men have inherited gene defects that boost their risk of developing prostate cancers that can be quite aggressive. Is PSA screening particularly well-suited for these genetically defined groups? New research […]

Treatments for advanced prostate cancer that suppress testosterone, a hormone (also called an androgen) that drives the malignant cells to grow and spread, are collectively referred to as androgen deprivation therapies, or ADT. These therapies can significantly extend lifespans in men who have the disease, but they also have a range of challenging side effects. […]

If a man has an enlarged prostate, there’s a good chance he’ll be treated with a type of drug called a 5-alpha reductase inhibitor (5-ARI). These drugs shrink the gland to improve urinary flow, and the approved forms used for treating enlarged prostates come in two varieties: Proscar (finasteride) and Avodart (dutasteride). However, a side […]

By now most of us are familiar with Brexit, the UK’s pending divorce with the European Union. But in a play on that term, British doctors are also moving towards an exit they’ve dubbed “TRexit” from the most common sort of prostate biopsy: the transrectal ultrasound guided biopsy, or TRUS. Men who test positive on […]

Not long ago, an abnormal PSA reading would be followed right away by a standard biopsy to search for potential cancer in the prostate. During such a procedure, doctors take 10 to 12 samples of the prostate from various locations while looking at the gland with an ultrasound machine. These days, however, men with high […]

Racial differences have long been evident in prostate cancer statistics. In particular, African American men are diagnosed with prostate cancer more often than white men, and they’re also nearly twice as likely to die of the disease. But new research also shows that African American men who receive the most advanced treatments for late-stage prostate […]

Men with advanced prostate cancer are typically treated with drugs that prevent the body from making or using testosterone. A hormone (or an androgen, as it’s known), testosterone drives prostate cancer cells to grow faster, so shutting it down is essential to keeping the illness in check. About 600,000 men with advanced prostate cancer in […]
