MRI-first strategy for prostate cancer detection proves deemed safe and effective
There are several strategies for the early detection of prostate cancer. The first step is often a blood test for prostate-specific antigen (PSA).

Another option is to use magnetic resonance imaging (MRI) to search for signs of a tumor before deciding whether a biopsy is necessary, reserving biopsies only for cases where abnormalities are detected.
