Prostate Cancer Overdiagnosed In Up To 42 Percent Of Cases

From "Tool determines risk of prostate cancer overdiagnosis" on ScienceBlog:
Studies have found that prostate cancer is overdiagnosed in up to 42 percent of cases, prompting men to receive unnecessary treatment that can cause devastating side effects, including impotence and incontinence.

Now, researchers at Fred Hutchinson Cancer Research Center and the University of Washington have developed a personalized tool that can predict the likelihood of prostate cancer overdiagnosis. They announced their findings this week in the online issue of the Journal of the National Cancer Institute.

An overdiagnosed cancer is defined as one that would never cause symptoms or pose a risk to the patient, therefore not require treatment. Treatment of such cancers provides no benefit and can only cause harm.
