Serious Warning Signs Of Bowel Cancer

Rectal Bleeding

In bowel cancer, cancerous cells grow and spread in the large intestine, invading and damaging the tissues of its lining and walls. This invasion of cancer cells can cause functional and structural problems in the large intestine, allowing its contents to irritate the damaged tissues further. When the cancerous cells cause damage to the intestinal tissues, they can rupture many of the highly concentrated small blood vessels that supply the intestinal tissues and linings with blood. There is also a high concentration of small blood vessels in the lining of the intestines to facilitate the proper absorption of nutrients and fluids from the food. The damage to these blood vessels causes blood to spill out into the contents of a patient's intestines. Blood in the stool is not reabsorbed, so it will appear as rectal bleeding when the individual has a bowel movement.
