According to the Colon Cancer Alliance, colorectal cancer is the third most commonly diagnosed cancer in the United States, and the second leading cause of cancer deaths. The American Cancer Society estimates that in 2012, 143,460 people will be diagnosed and that 51,690 will die from colon cancer in the United States. Appropriate screening is extremely important, as the survival rate for people with colorectal cancers found early is more than 90 percent.
Over seventy-five percent of colon cancer patients seem to have no inherited risk. However, research strongly suggests there are diet and lifestyle changes that can help reduce your risk of developing colon cancer. These include:
1. Receive regular colorectal cancer screenings beginning at age 50, assuming you have no known risk factors for the disease. If you are at higher risk – due to a family history of colon cancer, inflammatory bowel disease, or if you have a history of polyps in the colon – talk to your doctor about getting screened before the age of 50.
2. Eat a diet rich in fiber, complex carbohydrates, fruits, vegetables and plant sources of protein. Be sure to include plenty of cruciferous vegetables, as they have been shown to block the growth of colon cancer tumors. Cruciferous vegetables include: arugula, broccoli, brussel sprouts, cabbage, kale, cauliflower, bok choy, turnip greens and mustard greens.
3. Reduce, or better still, eliminate red meat from your diet. Information coming out of countries with the highest levels of beef consumption, such as New Zealand and Scotland, also have among the highest colon cancer rates in the world. In addition, a large Harvard study of 80,000 nurses, reported in the New England Journal of Medicine, found that eating any kind of red meat on a daily basis resulted in a threefold increased risk of colon cancer.
4. Reduce saturated fat intake. Studies suggest that saturated fat, found in fatty meat and high fat dairy products, including ice cream, milk and cheese, may trigger increased production of insulin and growth factors that seem to promote colon tumor growth. In contrast, diets high in omega-3 fats found in fish such as salmon, albacore tuna and rainbow trout can decrease inflammation that may lead to colon cancer.
5. Maintain a healthy weight and body composition. Excess weight is strongly linked to colon cancer, especially for men, premenopausal women, and those with excess fat predominantly in the abdomen. Since muscle weighs more than fat, recognize that healthy exercise that builds muscle while burning fat, may not change the scale, but it will still reduce your risk.
6. Incorporate physical activity into your life. Regular moderate activity such as brisk walking for 30 to 60 minutes a day doesn't just help with weight control, it can result in changes in various hormones and growth factors that help reduce the risk of colon cancer.
7. Don’t smoke, or quit smoking, and only drink alcohol in moderation.
8. Increase your antioxidants through a colorful selection of vegetables and fruits and reduce inflammation with cherries, fish and fish oil, and turmeric or its powerful anti-inflammatory component curcumin.
9. Research has consistently demonstrated that men and women with high blood levels of vitamin D, as well as those who consume more of the vitamin from dietary sources, have a significantly reduced risk of colorectal cancer.
10. Getting the right flora from probiotics like acidophilus can not only reduce your risk of getting colon cancer, but the risk of recurrence as well.

It is my experience that those who have not complied with a strict diet are also those who imagine that the psychological rewards could offset the inconvenience of the diet. I’m sure there are isolated cases such as you suggest, but most such individuals would quickly be dissuaded by the many inconveniences associated with dietary avoidance.hope this helps.
