Bowel Cancer Prevention

Prevention of bowel cancers, which are found in the lining of the colon and rectum, relies on a three-pronged approach. Colorectal cancer is preceded by a number of risk factors, some of which can be changed to dramatically reduce the possibility, while others cannot be helped. The chance of surviving bowel cancer, including evading surgery and removal of the stoma, can be greatly increased by understanding the symptoms. A combination of belonging to at-risk groups and being aware of the early symptoms will aid in detection and intervention. Regular examination is suggested for those belonging to high-risk groups.

Reducing the Risk of Bowel Cancer

Being a member of one or more of the following at-risk groups may suggest the need for more frequent examination. Those over 50 are most likely to receive diagnosis, though about 10 percent of cases occur between the ages of 40-50. Prior incidence of colorectal cancer is predictive of future diagnosis, as is a previous diagnosis of adenomatous polyps in the bowel wall or inflammatory bowel disease, specifically Crohn's disease and ulcerative colitis. A family history of colorectal cancer or the above disorders increases the risk as well. 

Fortunately there are several risk factors that can be eliminated or changed to support a healthy digestive system. Diet plays a major role in risk and is a key factor in prevention. A diet heavy in red meat and processed meats is a recognized contributor, though food can play a major role in both prevention and increasing the chances of full recovery. Studies have shown that raw vegetables are particularly important in prevention of bowel cancer. The allium family (garlic and onions), carrots and tomatoes also contain a number of compounds that support digestive health.

Exercise is also important. Those leading a more sedentary lifestyle with minimal of exercise are at higher risk. Regular exercise can also make recovery from colorectal cancer more likely. Those with difficulty exercising in traditional means can substitute low- and no-impact exercises, like swimming and yoga, to gain the same benefits.

Smoking and alcohol consumption are known to increase risk. It is especially important for those in one or more other high-risk groups to eliminate tobacco and limit alcohol to less than the equivalent of two glasses of wine a day.

Type 2 diabetes is the final major risk group. This kind of diabetes is most commonly associated with obesity and poor diet. Addressing the prevention advice relating to food and exercise is a great first step to limiting the risk from belonging to this group.

Symptoms Suggesting the Need for Screening

Being at risk means a need for regular tests, though only a physician can say how often. Besides the older tests, like the sigmoidoscopy and barium enema, doctors now have less invasive procedures, including blood test and stool sample. 

Appearance of the following symptoms indicate the need to talk with your doctor as soon as possible:

• blood in stool
• chronic fatigue
• abdominal pain, cramping and feeling full
• unexplained constipation, diarrhea or other stool abnormality
