Does tumour removal surgery treat anal cancer?

Anal cancer treatment depends on where the tumour is, its size, nearby lymph-node involvement and whether it has spread. A team may recommend medicines and radiation as the initial approach because this can treat the tumour while preserving normal anal function. Surgery may be considered when a small, accessible area needs removal, when cancer remains after initial treatment or when it returns.

The extent of an operation varies. It may remove the visible tumour and a margin of nearby tissue, or involve more extensive removal when the cancer cannot be controlled with local treatment. Your team will discuss bowel function, wound healing and possible changes to continence before recommending an operation.

Take your biopsy, scan and treatment reports to a colorectal or oncology consultation. Ask how the tumour's location affects options and whether a planned operation is intended as first treatment, follow-up treatment or treatment for recurrence. Discuss bowel preparation, pain control, wound care and support for bowel-function changes. Keep follow-up appointments even if symptoms improve.

Get urgent help for uncontrolled rectal bleeding, fainting, severe abdominal pain, inability to pass stool or gas, or new loss of bowel control with severe weakness. After surgery, promptly report fever, increasing pain, heavy bleeding, pus from the wound or inability to urinate.

Why is surgery recommended in my situation? Could medicines or radiation be used before an operation? How much tissue would be removed? What bowel-function changes should I expect? What follow-up will show whether treatment worked?
