boarder fagot: Colon Cancer

Definition
Colon cancer is cancer that occurs in the colon, the lower digestive system. Rectal cancer is cancer found in a few inches at the end of the colon. Many cases of colon cancer begins with small size, lumps of cells called adenomatous polyps are benign. These polyps usually cause colon cancer.

Symptom
Colon cancer has symptoms such as:
? Changes in bowel conditions, such as diarrhea or constipation or a change in bowel routines are not as usual
? there is bleeding in the rectum or blood in the stool
? Discomfort in the stomach area, such as cramps, bloating or pain
? Feeling of incomplete bowel movements when
? Weak
? Lost weight

Causes & Risk Factors
Cause
It is unclear what causes colon cancer. But doctors believe that colon cancer occurs when normal cells in the colon unchanged. Normal cells grow and divide to keep the body functioning normally. But sometimes it becomes abnormal growth ? cells continue dividing even when the body does not need a new cell.
In the colon and rectum, this exaggerated growth may cause pre-cancerous cells form in the digestive tract.

Pre-cancerous cell growth in colon
Colorectal cancer most commonly begins in the form of clumps of polyps in the colon tract. Polyps can be shaped like a mushroom. Polyps also can not stand out or hidden in the wall of the colon. Polyps of this type is more difficult to detect. Removal of both types of polyps before they become cancer earlier can help prevent colon cancer.

Inborn gene mutation that increases the risk of colon cancer
Inborn gene mutation that increases the risk of colon cancer can be inherited in families, but this is only a small fraction of colon cancer cause. Some colon cancer syndrome include:
? Familial adenomatous polyposis (FAP). FAP is a rare disease causes thousands of polyps in the colon and rectum channel. People who have FAP and untreated increases the risk of colon cancer before age 40.
? Hereditary nonpolyposis colorectal cancer (HNPCC). HNPCC, also called Lynch syndrome increases the risk of colon cancer and cancers with HNPCC tend lain. Uman colon cancer before age 50 years.

Risk factors
Some factors that increase the risk of colon cancer include:
? Aged parents
? Having a personal note with colon cancer or polyps
? Have an inflammation of the digestive tract
? genetic syndromes that may increase the risk of colon cancer, familial adenomatous polyposis such as hereditary nonpolyposis colorectal cancer and, which is also known as Lynch syndrome.
? Family history of colon cancer or polyps in the colon
? Eat foods high in fiber and low fat
? a passive lifestyle
? Diabetes
? Obesity
? Smoking
? Consuming alcohol
? Radiation therapy for cancer
