1. Presence of blood in the stool
The presence of blood in the stool reflects the presence of intestinal mucosal pain when the cancerous lesion extends and touches a small blood vessel.
Its color is usually red because the blood does not have time to be fully digested by the digestive tract, but can still be more or less dark.
Sometimes the bleeding is so small that it is not possible to distinguish it with the naked eye. Consult a specialist for an accurate diagnosis.
In a recent report published in the Asian Pacific Journal of Cancer Prevention, a study highlights the link between constipation and the risk of colorectal cancer. Constipation is an important indicator and may be a symptom of colon cancer.
In another study published in European Journal of Cancer in 2004, researchers confirm the hypothesis that constipation or excessive use of laxatives predisposes to colon cancer.
A tumor at the farthest end of the colon can be extremely difficult to treat and heal, resulting in constipation. If you have difficulty going to the saddle, for no specific reasons, the best is to consult a specialist.
