For men in their 60s who are diagnosed with early-state prostate cancer, surgery doesn't help them live significantly longer than those who wait and monitor the slow-growing disease, a landmark new study finds.

For nearly two decades, middle-aged men have been told by their doctors to have a routine PSA test to screen for prostate cancer.

When 81-year-old billionaire investor Warren Buffett recently revealed he had been diagnosed with early-stage prostate cancer after a routine screening blood test, many health experts wondered why a man of his age was even being tested for prostate cancer.

When the blood test for prostate cancer was introduced 26 years ago, it was seen as a way to save lives.
