Statistics show that one in 8 or 9 American women will develop breast cancer at some point in life, based on full life expectancy. The risk increases exponentially after age 30. The average age of women diagnosed with breast cancer is 60 years. However, the incidence in non-whites, specifically blacks, is increasing, particularly in women under age 60. Research suggests that a person's diet may affect the chances of getting some types of cancer .
Breast cancer appears to be more likely to develop in women whose diet is very high in fat .
Older women who are overweight also seem to have a greater risk. There are also studies that suggest a slightly higher risk of breast cancer among women who drink alcohol. The risk appears to go up with the amout of alcohol consumed. The possible link between diet and breast cancer is still under study. However, secondary prevention, early detection, and appropriate treatment early in the disease process, may be promoted through routine breast self-exam beginning around age 20 and screening mammography after age 40.
