Treatment of colon cancer has changed significantly over the past decade. For many years, colon cancer patients had only one drug to use, and it was not very effective. Today, there are many treatments available for colon cancer, although access to these treatments remains a challenge in many countries.
Treatment largely depends upon the location of the tumor in the colon or rectum and the stage of the disease. Treatment for colorectal cancer may involve surgery, chemotherapy, biological therapy or in some cases, radiation. Some people have a combination of treatments. Treatment for colon cancer is sometimes different than treatment for rectal cancer. Cancer treatment can be local therapy or systemic therapy.
