About this test

CA 72-4 is a tumour marker that may be raised in stomach cancer and some ovarian and bowel cancers. It is mainly used to monitor treatment, not to screen healthy people.

Why is this test done?

  • Monitor stomach cancer treatment
  • Look for recurrence after surgery
  • Support diagnosis with other tests

Symptoms — when should you get tested?

  • Known stomach or ovarian cancer
  • Upper belly pain and fullness
  • Weight loss and vomiting

Normal range

Adults < 6.9 U/mL

Reference ranges differ slightly between labs, methods, age and sex. Always discuss your report with your doctor.

If your result is high

A high or rising CA 72-4 can mean cancer activity, but it can also rise in non-cancer conditions.

Common reasons
  • Stomach cancer
  • Ovarian or colorectal cancer
  • Pancreatitis, liver disease or gastritis
