Prostate cancer screening is particularly important for South Asian men, who may have a higher risk. The NHS recommends that men aged 50 and above should discuss the PSA test with their GP. For those with a family history of prostate cancer or who are of Black ethnicity, discussions should begin at age 45. It's essential to understand that the PSA test measures the level of prostate-specific antigen in the blood, which can indicate potential issues, but is not definitive for cancer. Early detection can lead to better treatment outcomes, so having regular conversations with your healthcare provider is crucial.
