PSA tests are used to monitor cancer control after treatment for prostate cancer.

  • Your PSA drops more quickly after surgery than radiotherapy.
    In most men, it stays low or undetectable for many years.
  • The period after treatment is a chance to improve your diet, exercise and weight – it may help your prostate cancer outcome.
  • If the PSA starts to rise again after surgery, salvage radiotherapy still offers a chance of cure.
