| Colon Cancer diagram by Joe Lertola |
1. Cells that line the colon are very active,
constantly dividing and creating buds, known as polyps. Most polyps are small,
benign growths that eventually stop growing.
2. But a tiny percentage of these polyps keep
growing, sometimes for 10 years or more. Various genetic mutations can
transform them into cancerous tumors.
3. As these tumors grow larger, they gather more
mutations and begin to burrow deeper and deeper into the muscle wall that
surrounds the colon.
4. Once the cancer invades the blood and lymph
systems, malignant cells can break off and spread to other organs, such as the
liver, lungs, and stomach.
