Dietary Patterns among Colorectal Cancer Patients in Southwest of Iran: A Cross-Sectional Study

Colorectal cancer is one of the three most common cancers in the world and also one of the four leading causes of death among cancerous patients with global prevalence [1,2]. This cancer is associated with a high incidence and mortality among developed countries [3]. In Iran, which is located in southwest Asia, colorectal cancer is one of the five most common cancers in both genders and in the Khuzestan province (in the south west of Iran) colorectal cancer is among the eight most common cancers [4]. Genetic and environmental factors are involved in the incidence of colorectal cancer. Nutrition also plays an important role in the incidence and control of this disease. Recent studies have shown that improved eating diet could potentially reduce colorectal cancer up to 70 percent. High-fat meals especially meals rich of saturated animal fat that are common in Western diet increases chances of involvement by this cancer [5].
