Case-control Study of Breast Cancer and Dietary Fat Intake in Saudi Females

Breast cancer is the most common cancer worldwide and is the leading type of cancer among women. The breast cancer burden predictably will continue to increase in the coming years; there could be a nearly 50% increase in global incidence and mortality between the years 2002 and 2020 because of demographic changes alone. The etiology of breast cancer is multifactorial; however, the exact cause of breast cancer is still unclear because the disease presumably represents a complex interplay of genetic susceptibility and environmental factors, such as dietary fat intake, hazardous effects of hormonal exposures, and long-term use of hormone replacement therapy.
