Prostate cancer is the most common cancer diagnosed among men in the United States -- affecting nearly 200,000 men every year. There are several treatment options, but new research shows there may be a way to prevent the disease altogether.
Doctors hope that the drug -- finasteride -- will make a difference in preventing prostate cancer. In smaller doses, it's commonly known as Propecia for baldness. It works by stopping testosterone's conversion to DHT -- a more active form of the hormone. It is known that prostate cancer is a hormone-dependent cancer. DHT is more active and more potent in prostate cancer development.
AdvertisementA study of more than 20,000 men showed finasteride decreased prostate cancer risk by 25 percent. Researchers say no more than 3 percent of the men in the study had side effects, including mild sexual dysfunction. However, they say when the drug was stopped, sexual function was returned to normal.
