Treatments for stage 1 colon cancer

The following are treatment options for stage 1 colon cancer. Your healthcare team will suggest treatments based on your needs and work with you to develop a treatment plan.

Surgery

Surgery is the main treatment for stage 1 colon cancer. A bowel resection is the type of surgery done. Depending on the location of the tumour, the surgeon may do a right hemicolectomy, transverse colectomy, left hemicolectomy, sigmoid colectomy, subtotal colectomy or total colectomy.

The surgeon also removes at least 12 nearby lymph nodes (called lymph node dissection).

A colostomy may be done to allow the intestines to rest and heal after bowel resection. The colostomy is usually temporary. The 2 ends of the colon are joined together after they have healed.

Clinical trials

You may be asked if you want to join a clinical trial for colon cancer. Find out more about clinical trials.
