Prostate-specific antigen (PSA) is a protein made by cells in the prostate gland (both normal cells and cancer cells). PSA is mostly found in semen, but a small amount is also found in blood.
Elevated PSA levels can indicate the presence of cancer, but high PSA levels can also be a result of non-cancerous conditions like benign prostatic hyperplasia (BPH), or an infection. PSA levels also rise naturally as you age.
