Fruit vegetable consumption low (<3 times/week) 35.5% red meat high (≥3 47.4% Median time-to diagnosis 3.0 months 4.0 cancer, respectively. Mean body mass index >25 all group Distal (61.3%) sigmoid (36.8%) most common locations 85.6% operated; 25.8% emergency surgery. Low anterior resection rate 64.2% cancer. majority (89.8%) who received preoperative treatment, conventional chemo-radiotherapy regimen given. pTNM staging at showed that stage III IV (35.9% 29.7%, respectively).Colon is more frequent than Turkey.
