Anal cancer

Treatments for stage 0 anal cancer

The following are treatment options for stage 0 anal cancer. Your healthcare team will suggest treatments based on your needs and work with you to develop a treatment plan.


Surgery is the main treatment for stage 0 anal cancer. Wide local excision is usually done to remove the tumour and a small amount of healthy tissue around it (called the surgical margin). Sometimes more surgery is needed to remove any cancer left behind or if cancer cells are found in the surgical margin.

Clinical trials

You may be asked if you want to join a clinical trial for anal cancer. Find out more about clinical trials.
