Surgery for Advanced Bowel Cancer

Surgery for advanced bowel cancer may be considered in some situations, depending on where the cancer is, how far it has spread, symptoms, previous treatments and overall health. Surgery may aim to remove cancer, relieve symptoms or improve quality of life.

This article is for general information only. Surgery decisions should always be discussed with your surgeon, oncologist and healthcare team.

When Surgery May Be Considered

Surgery may be considered if bowel cancer has spread but can still be removed safely, or if the cancer is causing symptoms such as blockage, bleeding or pain. In some cases, surgery may be used together with chemotherapy, radiation therapy or other treatments.

The best approach depends on the individual situation. Your specialist team can explain whether surgery is suitable and what the goal would be.

Surgery for Bowel Obstruction

Sometimes bowel cancer can partly or fully block the bowel. This is called bowel obstruction. Symptoms may include abdominal pain, bloating, vomiting, constipation or inability to pass stool or gas.

If obstruction happens, treatment may include surgery, a stent or symptom control depending on the person’s condition. You can read more in our Surgery for a Blocked Bowel article.

Surgery for Cancer Spread

If bowel cancer has spread to a limited area, such as part of the liver or lungs, surgery may sometimes be discussed. This depends on the number, size and location of cancer deposits and whether the person is fit enough for surgery.

These decisions are usually made by a multidisciplinary team of specialists.

Possible Benefits and Risks

Surgery may help remove cancer, reduce symptoms or prevent complications. However, surgery also has risks such as infection, bleeding, blood clots, bowel changes, pain, fatigue or the need for a stoma.

Before surgery, ask your surgeon what the operation is expected to achieve, what risks apply to you and what recovery may involve.

Recovery After Surgery

Recovery can take time. Some people need help with walking, eating, wound care, bowel changes, fatigue or stoma care after surgery.
