The type of surgery you have depends on the stage of your cancer and where it is in your anus. Find out about the different types of surgery for anal cancer, what happens before surgery and how you might feel after your operation.
You might have surgery for anal cancer if you have a very early cancer (stage 1) of the anal margin. Or if you've had chemoradiotherapy that didn't get rid of the cancer completely.
Before surgery, you have tests to check your fitness and you meet members of your treatment team.
You have a general anaesthetic so you can't feel anything during the operation. This sends you into a deep sleep.
You have a colostomy if you have an operation called an abdominoperineal resection. Find out what a colostomy is and why you might have one.
How you feel after your operation depends on what type of surgery you have.
