Is colon cancer curable at Stage 3?

A stage III colon cancer has about a 40 percent chance of cure and a patient with a stage IV tumor has only a 10 percent chance of a cure. Chemotherapy is used after surgery in many colon cancers which are stage II, III, and IV as it has been shown that it increases the survival rates.

Is colon cancer aggressive or slow growing?

In general, colorectal cancers tend to be slow growing, gradually enlarging and eventually penetrating the bowel wall. When they do spread, it is usually through invasion of nearby lymph nodes. In fact, cancer cells may enter a lymph node even before the tumor penetrates through the intestinal wall.
