PSA & Prostate Screening
PSA (prostate-specific antigen) is the main test used for prostate screening. This page explains what a PSA level means, when it's checked, and why a high result doesn't always mean cancer.
Also known as: PSA Test · Prostate-Specific Antigen · Prostate Screening
Preparation: No fasting needed; avoid ejaculation and cycling for ~48h before.
PSA is a protein made by the prostate; its level can rise with cancer, but also with benign enlargement, prostatitis, or after cycling or ejaculation. So a single result is read in the context of age and trend.
Screening is usually discussed with a doctor from around age 50 (earlier with a family history). Below is the marker itself; tap to read more.

Frequently asked questions
Does a high PSA mean cancer?
Not necessarily. PSA rises with benign causes too (enlargement, inflammation). A doctor weighs the level, the trend and the free/total ratio, and orders further work-up if needed.
When should screening start?
It's usually discussed from around age 50, earlier with a family history of prostate cancer. The decision is made individually with your doctor.
