What to expect from tumour removal surgery for anal cancer

The surgical plan depends on whether the tumour can be removed while preserving the anal muscles and nearby organs. A local procedure may be possible for a small, accessible tumour. More extensive surgery can involve the anus and rectum and may create a colostomy, an opening on the abdomen for stool to leave the body into a pouch. Your team will explain how the operation affects bowel control, skin and daily routines.

The removed tissue is examined to guide further care. Some people have chemotherapy or radiotherapy before surgery, while others need additional treatment afterward.

Before admission, ask about bowel preparation, fasting, medicines and stoma teaching if a colostomy is possible. At home, follow wound-care instructions, keep the area clean and use pain relief as directed. Gentle movement supports recovery, but avoid lifting until cleared. A stoma nurse can teach pouch changes and protect the surrounding skin. Tell the team about constipation, diarrhoea, difficulty passing urine or new problems controlling stool.

Call the surgical team for increasing pain, wound separation, pus, persistent fever, heavy bleeding, inability to pass urine or a stoma that becomes very swollen or stops passing stool and gas. Go to emergency care for severe abdominal pain, fainting, breathing trouble or uncontrolled bleeding.

Ask which operation is recommended, whether a temporary or long-term stoma is possible, how bowel function may change, when bathing and exercise are safe, who will support wound or stoma care and when pathology results are expected.
