How often does colon cancer metastasize?

How fast does colon cancer metastasize?

Where does colon cancer usually metastasize first?

The most common include the liver and lungs, as well as the brain, distant lymph nodes and peritoneum (membrane that lines the abdominal cavity).

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.
