5. Future Research
    Further clinical trials focussing on adjuvant chemotherapy and immunotherapy are needed both to improve
    the effectiveness of current treatments and try to understand drug and immune mechanisms. Studies are also
    needed to determine the optimum role of radiotherapy in rectal cancer.

For Dietary Prevention of Colorectal Cancer
Recommendations
• The diet should stress high fiber and low fat.
• Increased growth rate of colon membrane cells may precede colon cancer. Chemoprevention is being tested
  with micronutrients—vitamins and minerals.
• Calcium may help by regulating cell overgrowth.
• Other factors are stool acidity (pH) and the effect of bile and fatty acids on the colon's lining (mucosa).
  Depending on acidity, calcium may help regulate the cancer-promoting role of bile acids and fatty acids.
• A women's trial has shown a 2 1/2 times normal risk of colon cancer when red meat (pork, beef, lamb) is eaten
  daily (animal fats) rather than a few times a month. (Vegetable fat was not a risk factor.)
• 1,200 - 2,000 mg daily calcium intake (in skim milk or substitute, food or pills) to help reduce colorectal cell
  growth, especially if a polyp has already been found.
