What is the relationship between psa test bph and prostate cancer?

The PSA test measures the level of prostate-specific antigen in the blood, which can be elevated in both benign prostatic hyperplasia (BPH) and prostate cancer. While BPH is a non-cancerous enlargement of the prostate that can cause increased PSA levels, prostate cancer can also result in elevated PSA. Therefore, a high PSA level does not definitively indicate cancer, as it can be due to BPH or other prostate conditions. Further evaluation, including biopsies and imaging, is often necessary to distinguish between these conditions.
