Colorectal cancer is cancer that develops from the cells of the large intestine. The large intestine consists of colon and rectum. The rectum is the last 15 cm of the large intestine and is located in the pelvic cavity, in the middle of the hip bone.
Rectal area is a very small area, so the distance between cancer and surrounding normal organs is very short. Therefore, the possibility of cancer spread to surrounding organs is significant.
Another part of the large intestine whose position lies above the hips is called colon. The colon is surrounded by a fatty tissue, called the momentum, and attached to the abdominal wall, by more fatty tissue, called mesenterium. In mesentery, there are lymph nodes.
Cancer can develop from cells of the lining of the colon and can cause bowel obstruction, or bleed in the stool.
Risk Factors for Rectal Cancer
Anything that increases your chances of getting the disease is called a risk factor. If you having a risk factor does not mean that you will get cancer, and vice versa if you do not have risk factors, it does not mean that you will not get cancer.
Consult your doctor if you think you have been exposed to the risk of the disease. The following are common risk factors that trigger rectal cancer:
- Age over 50 years.
- It has certain hereditary conditions, such as familial adenomatous polyposis (FAP) and hereditary colon cancer nonpolyposis (HNPCC or Lynch syndrome).
- Have a parent with a history of illness as below:
- Colorectal cancer
- Polyps (small bloated pieces of tissue) in the colon or rectum
- Endometrial cancer
- Breast cancer
- Colon cancer
