Test could identify which prostate cancers require treatment

The level of expression of three genes associated with aging can be used to predict whether seemingly low-risk prostate cancer will remain slow-growing, according to researchers. Use of this three-gene biomarker, in conjunction with existing cancer-staging tests, could help physicians better determine which men with early prostate cancer can be safely followed with "active surveillance" and spared the risks of prostate removal or other invasive treatment.http://feeds.sciencedaily.com/~r/sciencedaily/~3/2...
