Medication
Radiation therapy is the kind of treatment that uses high energy X-rays or particles to destroy cancer cells. For some people with colon cancer treating them with chemotherapy and radiation therapy at the same time can work very well. The use of chemotherapy and radiation therapy together is known as chemoradiotherapy.
Procedures
Doctors often use chemotherapy alongside other treatments to treat colon cancer, so it is difficult to determine each treatment’s effectiveness and success rates. The 5-year survival rate across the four stages of colon and rectal cancer is 63–67%.
Therapy
Chemotherapy may also be used after surgery (called adjuvant treatment). Most adjuvant treatment is given for about 6 months. Treating stage 0 colon cancer Since stage 0 colon cancers have not grown beyond the inner lining of the colon, surgery to take out the cancer is often the only treatment needed.
