If someone has symptoms and signs of colon or rectal cancer, the doctor will suggest these tests for making the diagnosis.

  • Faecal immunochemical test for occult blood: this test is done on stool. It is used mostly as a screening test.
  • Colonoscopy: it is a procedure in which a flexible thin tube with a camera is passed and colon is seen from inside.
  • Biopsy: if any abnormality is seen on colonoscopy then a tiny bit of it is taken and examined under a microscope.
  • Serum CEA: CEA is a tumour marker, which can be elevated in colorectal cancer.
