Breast cancer affects us all. The American Cancer Society, estimates that in 2009, 200,000 new cases of invasive breast cancer were diagnosed as well as over 62,000 cases of in situ breast cancer. There were 1,1 Million cases of Breast cancer and 373,000 deaths in women in 2000.. Breast cancer is second most common form of cancer in the world, and the number one cancer affecting women. Breast cancer affects our mothers, sisters, daughters, friends and neighbours. Breast cancer affects us all.
A study published in Public Health Nutrition, “Diet, Nutrition and the Prevention of Cancer” showed women in the Western world are five times more likely to get breast cancer, than women in less developed countries and Japan.
One of the significant differences that is proposed to play a role in the incidence variation is due to dietary habits and physical activity. These factors can be further broken down into there categories:
Obesity increases the risk of breast cancer in postmenopausal women by approximately 50%. This drastic increase in risk is attributed to the increasing serum concentrations of free oestradiol. Although, pre-menopausal women did not carry this risk, with obesity tending to be life long battle, obese women will eventually face this risk.
Alcohol is an established dietary risk factor for breast cancer. There is a growing amount of data that consistently indicates increased risk correlated to increased alcohol consumption.
Although there are many adverse effects of high fat intake, breast cancer has not conclusively been found as one of those risks. There is a great deal of research and controversy, however current research does not support this.
