How Is Colon Cancer Treated?


Katherine Banwell:

Let’s start with a basic question. What are the stages of colon cancer?

Dr. Krishnamurthi:

Colon cancer is categorized in four stages – stage 1, 2, 3, 4. This takes into account the tumor itself, how thick it is. These tumors start on the inside of the colon, like as a polyp. Then they can grow through the colon wall. The tumor thickness and has it spread to any of the lymph nodes? and has it spread further to a distant organ like liver or lungs?

That’s a tumor node metastasis. Considerations that go into the staging. Stage 1 colon cancer or colorectal cancer would be a very shallow tumor, maybe just in a polyp and hasn’t spread to any nodes or anywhere else. Stage 2 is when the tumor is thicker. It may be involving the full thickness of the colon or rectum but has not spread to any nearby lymph nodes. Stage 3 is when the cancer has spread to regional or nearby lymph nodes. Stage 4 is when it’s metastatic or it’s spread to another organ.


Okay. Thank you.
