How does colon cancer affect the circulatory system?

For example, cancers of the colon (large bowel) often spread to the liver. This is because blood circulates from the bowel through the liver on its way back to the heart. So if some cancer cells escape into the circulation, they may stick in the liver as the blood passes through.

What happens to a tumor after radiation?

When the damaged cells die, they are broken down and removed by the body. Radiation therapy does not kill cancer cells right away. It takes days or weeks of treatment before DNA is damaged enough for cancer cells to die. Then, cancer cells keep dying for weeks or months after radiation therapy ends.
