Study: prostate cancer patients may benefit by waiting on treatment

A new study on prostate cancer offers more evidence there may not be much benefit to early detection and extensive treatment. Researchers now estimate as many as 42 percent of prostate cancers are over diagnosed. That means a PSA screening test found cancer cells. But those cells will never grow enough to be a threat.

Treatment can have significant side effects. So doctors say most men diagnosed with prostate cancer would benefit from waiting to see if the cancer actually grows.

The study is published in the Journal of the American Cancer Institute.
