A recent study at the Kimmel Cancer Center that examined the role of the Western diet and its link with breast cancer has found that fat and cholesterol play a much larger role in breast cancer risk than previously thought, according to Times of India
"These facts suggest strong environmental influence of breast cancer development," Phillippe G. Frank, assistant professor at Thomas Jefferson University told the news source.
The study used lab mice to recreate the Western diet and compare it to other developed countries. The results found that the mice consuming a Western diet were more predisposed to develop mammary tumors, which grow and metastasize far quicker than the mice fed the control diet.
Outside of the recent experiment, scientists can point to the fact that the incidence rate of breast cancer is five times as large in Western countries than other developed nations. This is coupled with recent statistics that show that immigrants who have come from areas with low instances of breast cancer to a Western country will see an increase in their risk for breast cancer.
According to the American Cancer Society, women should undergo annual mammograms beginning at age 40.
