You may have more tests after your diagnosis to find out:

  • How large is the cancer?
  • Where exactly is the cancer?
  • Has the cancer spread to any other parts of your body?

This is called staging. Staging tests for anal cancer include:

  • Blood tests: To check your general health
  • CT scan: A special type of X-ray to give a picture of the tissues inside your body
  • MRI scan: A scan that uses magnetic energy to build up a picture of the tissues inside your body. 
  • Ultrasound scan: A device called a probe is passed into your back passage (rectum). It uses sound waves to give a picture of the tissues there. It can show any abnormal changes. 
  • PET scan: A radioactive injection that will show up any cancer spread to other parts of your body on a CT scan picture.
