There are several strategies for the early detection of prostate cancer. The first step is often a blood test for prostate-specific antigen (PSA). If PSA levels exceed a certain threshold, the next step typically involves taking a tissue sample for analysis. 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. Researchers at conducted a study to determine whether this MRI-first approach is safe over the long term. Their findings show that this strategy poses no additional risk to patients for at least three years.
