Colorectal Cancer – Information on bowel cancer
Monday, February 22nd, 2010Colorectal cancer may also be called rectal, colorectal or colon cancer. But when the cancer has spread to the lining of the intestine, it is difficult to treat. The statistics of colon cancer in these pages are designed for use by health professionals. If you are looking for information because you or someone you know has been affected by cancer, then the Cancer Help pages of the UK colorectal cancer may be more significant and relevant. Cancer Help UK also has a clear guide to understanding statistics.
Large intestine, also called the colon, the last part of your digestive system. The food passes through your small intestine (the longer, thinner part of your intestine), where nutrients are absorbed. Food waste then travels through the colon (large intestine), where it faces stronger. The colon has three sections – the ascending transverse and descending> Colon. Rectum, the end of the colon, is where it is joined to the anus as what a relief.
The cancer develops when a cell of the colon, a series of changes (mutations) in some of the genes that determine the cell divides and survives developed. Consequently, the uncontrolled cell divides to form a clump of malignant (cancer) cells. Initially, these lesions jointly produce a polyp (a clump of abnormal cells the size of a pea on the end of a stalk of normal cells) called an adenoma.
Intestine is long "tube", which absorb water and nutrients from food and waste products of the processes in the face. These include the small bowel, colon and rectum. Colorectal cancer is diagnosed in more than 3,400 Victorians and more than 12,500 Australians each year. This is especially with those older than 50 years, but can occur in younger people. Cancer of the colon is also known as Colo> Cancer.
Colorectal cancer is caused by abnormal and uncontrolled growth of cells in the lining of the colon. Normally, a colon cancer develops from small, non-cancerous (benign) tissue growths called polyps, which can extend from the lining of the intestinal wall. Sometimes these can become cancerous (malignant). If the cancer is not treated, can grow through the bowel wall and spread to other parts of the body.
When food is swallowed, it Go down the throat (esophagus), stomach, where digestion begins. E 'then run through the small intestine, where essential nutrients are taken into the body. The digested food then moves into the colon, and the water is absorbed by the colon. Large intestine begins at the bottom, right abdomen. The first part rises and is known as the ascending colon. It will then proceed to the left of the stomach. This part is known as the transverse> Colon. Will go to the bottom of the stomach: this is a part of the name of the descending colon, and ends in the sigmoid, rectum and anus.
Although the exact cause of colon cancer, is not understood, is known genetics may play a role. Specific genetic mutations can colorectal cancer or hereditary diseases are known to cause susceptibility to the condition. For example, familial adenomatous polyposis (FAP) is responsible for about one percent of all cases of cancer incolon and rectum. It caused widespread development of polyps in the colon from outside through adolescence, many of which were quickly cancer.
