What causes increased PSA levels?

In men with cancer, prostate cancer cells usually make more PSA than do benign cells. This causes PSA levels in the blood to rise.

But PSA levels can also be elevated in men who don't have prostate cancer. Conditions that could lead to an elevated PSA level in men who don't have prostate cancer include:

  • Benign prostate enlargement (benign prostatic hyperplasia)
  • A prostate infection (prostatitis)
  • Other less common conditions
