Chemoprevention

Chemo :
As discussed in Heart Disease and Nervous System Disorders, regular use of low-dose aspirin (81–325 mg) can reduce the incidence of myocardial infarction in men. Low-dose aspirin reduces stroke but not myocardial infarction in middle-aged women. Based on its ability to prevent cardiovascular events, aspirin use is cost-effective for men and women who are at increased risk. Nonsteroidal anti-inflammatory drugs may reduce the incidence of colorectal adenomas and polyps but may also increase heart disease and gastrointestinal bleeding, and thus are not recommended for colon cancer prevention in average risk patients. Antioxidant vitamin (vitamin E, vitamin C, and beta-carotene) supplementation produced no significant reductions in the 5-year incidence of—or mortality from—vascular disease, cancer, or other major outcomes in high-risk individuals with coronary artery disease, other occlusive arterial disease, or diabetes mellitus.
