The male hormone testosterone contributes to normal brain function, and some research links memory loss in older men to testosterone declines that occur naturally with aging. However, testosterone is also like jet fuel for prostate tumors, causing them to grow faster, so during cancer treatment doctors will often give hormonal therapies that suppress its activities […]

Charles Schmidt As they get older, do men with prostate cancer come to regret the treatment decisions they made? A new study of men diagnosed during the mid-1990s indicates that some of them will. Richard Hoffman, a professor of internal medicine and epidemiology at the University of Iowa Carver College of Medicine in Iowa City, […]

Charles Schmidt Does screening for prostate cancer with the prostate-specific antigen (PSA) test save lives? A new study suggests that it does, but at the risk of exposing men with slow-growing tumors that may not be life-threatening to treatments they may not really need. Published in Annals of Internal Medicine, the study reconciles conflicting results […]

Charles Schmidt In the 1980s, reports began to surface of a potential connection between vasectomies and prostate cancer. This worried men considering vasectomies for birth control, but it was also controversial. Some studies detected an association while others didn’t. Harvard Prostate Knowledge last covered the topic in 2015, after the largest study to that point […]

Charlie Schmidt A standard approach for treating aggressive prostate cancer is to give therapies that block testosterone, a tumor-stimulating hormone. Should initial hormonal therapies fail, doctors can switch to other drugs that suppress testosterone in different ways. One of them, a drug called abiraterone, has been shown to significantly extend lifespans in men who have […]

Charlie Schmidt Decades of research show that yoga can reduce the emotional and physical fatigue brought on by cancer treatment. Now researchers have shown for the first time that’s also true specifically for men being treated for prostate cancer. Men who took a yoga class twice a week during treatment reported less fatigue, fewer sexual […]

Charlie Schmidt In 2012, the US Preventive Services Task Force (USPSTF) took the unprecedented step of recommending against prostate cancer screening for all men, regardless of age, race, or family history. Now this influential group of independent experts is reassessing its position based on more recent data. Instead of discouraging screening altogether, the UPSTF is […]

Charlie Schmidt In April, scientists reported encouraging results from a pilot study of men with metastatic prostate cancer, or cancer that has spread beyond the prostate gland. Long considered incurable, these advanced cancers are usually treated by giving men systemic drugs that target new tumors forming in the body. The scientists who led this new […]

High-grade cancer that’s still confined to the prostate is generally treated surgically. But a third of the men who have their cancerous prostates removed will experience a rise in blood levels of prostate-specific antigen (PSA). This is called PSA recurrence. And since detectable PSA could signal the cancer’s return, doctors will often treat it by […]

Men who have high levels of prostate-specific antigen (PSA) in their blood face troubling uncertainties. While it’s true that prostate cancer can elevate PSA, so can other conditions, including the benign prostate enlargement that afflicts many men as they get older. PSA levels also vary normally from one man to the next, and some men […]
