The PSA test (Prostate-Specific Antigen test) is a blood test used to screen for prostate cancer. It measures the level of PSA in your blood, with higher levels potentially indicating the presence of cancer. Men aged 50 and older, or those with a family history of prostate cancer, should consider this test. It’s important to discuss with your GP whether this test is right for you, as it can help in early detection, increasing the chances of successful treatment.
