Tests and next steps for bowel cancer

Main tests for bowel cancer

If a GP refers you to a specialist because they think you could have bowel cancer, you'll have tests to check for cancer.

The main test for bowel cancer is a colonoscopy. This is where a thin, flexible, tube with a camera is used to look inside your bowel.

It may be uncomfortable but it should not be painful. You'll be offered a sedative and painkillers to help make you feel more comfortable.

During the colonoscopy, a small sample of the lining of your bowel may be taken for testing (called a biopsy)

Getting your results

You may get some results on the same day that you have the colonoscopy, or after a few days.

You can call the hospital or your GP if you're worried and they may be able to update you if your results are ready.

If you're told you have bowel cancer

Being told you have bowel cancer can feel overwhelming. You may be feeling anxious about what will happen.

You'll be helped through your diagnosis and treatment by a team of specialists.

This team will include a clinical nurse specialist who will be your main point of contact during and after your treatment. You can ask them any questions you may have.

Next steps

If you've been told you have bowel cancer, you may need more tests which can include:

• a CT scan
• an MRI scan
• a PET scan
• blood tests
• genetic testing

The results of these tests can show how far the cancer has spread, and if the cancer has been caused by certain changes in your genes.

This will help your specialist team decide what treatment you need.
