Colon cancer is a disease that develops because the colonic mucosa contained in an existing polyp evolves from causes into a malignant tumor. Malignant cells usually are located in the intermediate and longer portion of the large intestine.
This type of cancer is one of the most common worldwide and also the easiest to diagnose. Moreover, cure rates are high if detected early and takes a long time to develop.
The colon along with the rectum (final portion of the large intestine) is where feces are stored before being expelled to the outside through the anus. To undertake this work, accumulate waste substances, so it is conducive to the development of cancer instead. Therefore it is important to reduce the accumulation time to a minimum by adopting a balanced diet to provide adequate intestinal transit preventing constipation.
Colon cancer can grow in three ways:
Local growth: In this case the tumor invades deeply all layers of the gut wall. First, the malignant tumor growing from the mucosa, expands the serosa and muscle layers reaches. By the time the cancer through the wall of the bowel can spread to all organs.
Lymphatic spread: When the tumor is deepened in the bowel wall can reach the organs using the network of lymph vessels that allow access to multiple lymph node regions. One feature of this broadcast is being done in an orderly reaching nearby lymph first to reach the farthest.
Hematogenous spread: Here the tumor uses the bloodstream to spread cancer cells to the liver, lungs, bones and brain, mainly.
OPINION: In all types of cancer risk factors that make people who are exposed to them are more likely to develop a malignancy.
so we must keep in mind that it is important to realize ourselves different studies and checkups prebenir these diseases.
