Prostate-Specific Antigen (PSA) is a protein produced by both normal and cancerous cells in the prostate gland. It is found in small amounts in the blood of healthy men, but levels can be higher in those with prostate cancer or other prostate conditions. PSA testing measures the level of this protein in the blood to help detect potential prostate issues early on.
PSA testing is important because it can help identify prostate cancer at an early stage when treatment may be more effective. It is commonly used as a screening tool for men, especially those over the age of 50 or those with a family history of prostate cancer. While a high PSA level does not always mean cancer is present, it can lead to further testing or monitoring to ensure proper diagnosis and care.
In the body, PSA helps to liquefy semen, allowing sperm to move more freely. While it serves a vital function in reproductive health, elevated levels in the blood can indicate problems with the prostate. Understanding PSA levels can aid in the early detection of prostate cancer, which is crucial for improving survival rates.
It is important for men to discuss PSA testing with their healthcare provider, considering factors such as age, health history, and risk factors for prostate cancer. Regular monitoring can provide valuable insights into prostate health and guide appropriate medical decisions.
