Surgery for colon cancer

Surgery is one of the main treatments for colon cancer, with different possibilities based on the type and stage of your cancer. When colon cancer is found in its earliest stages, surgery is often the only treatment required. In later stages, surgery is used together with other treatments to fight colon cancer.

Surgical treatment aims to remove the primary colon cancer as well as the associated lymph nodes and affected tissue. Surgery is also used to help manage or relieve symptoms of colon cancer. Depending on how much your colon cancer has grown or spread, you may have minimally invasive surgical options or treatments to preserve your normal digestive function.

Medical treatment

In advanced stages (3 or 4) of colon cancer, a combination of medical and surgical treatments is often used. In some advanced types of colon cancer, medical treatments may be the primary source of care.

Common medical treatments include chemotherapy, radiation therapy, targeted therapies or immunotherapy. The choice and sequence of treatments depend on several factors, and if one treatment is ineffective, your care team may explore alternative medical options.

Radiation therapy

Radiation therapy for colon cancer isn’t a standard colon cancer treatment. It’s more common in rectal cancer care. However, it may be used with chemotherapy, called chemoradiation, for specific cases.

If your care team recommends radiation therapy, you’ll talk about the goals of your specific treatment. Radiation therapy can reduce the size of a tumor before surgery, destroy cancer cells that remain during or after surgery or reduce symptoms of advanced-stage colon cancer.

Types of radiation

During this therapy, your care team uses high-energy beams of radioactive material to help destroy cancer cells. The two main types of radiation are external-beam radiation therapy and brachytherapy.

External-beam radiation therapy: This therapy delivers radiation from a machine outside the body. It’s the type of radiation used most often in colon cancer treatment.
Brachytherapy: Also known as internal radiation therapy, brachytherapy delivers radiation via a needle or catheter inside the body.

Colostomy or ileostomy

If you need surgery to remove your colon to treat colon cancer, your care team may talk with you about an ostomy procedure, such as a colostomy or ileostomy.

These procedures reconnect your intestinal tract to an opening in the abdomen called a stoma. Stomas allow stool to pass out of the body into a pouch. When the end of the small intestine is connected to the stoma, it’s called an ileostomy. When the remaining portion of the colon is connected, it’s called a colostomy.

With advances in surgery, many colon cancer surgeries use anastomosis, which reconnects the digestive tract on the inside and eliminates the need for an ostomy. Some people require a temporary colostomy or ileostomy to give their body time to heal. According to the Colorectal Cancer Alliance, less than 10% of people who undergo colon cancer surgery will have a permanent colostomy or ileostomy.

If you need a temporary or permanent colostomy or ileostomy, many of our locations provide specially trained ostomy nurses who will equip you with the knowledge to manage your stoma and pouch confidently.
