title: Obesity and colorectal cancer.
abstract: BACKGROUND
  To correlate obesity and colorectal cancer for Greek living conditions.
  
  
  METHODS
  We studied 97 patients, who over the last 5 years were diagnosed histopathologically with colorectal cancer. 75.3% of the patients were either overweight or centrally obese; secondly, 21.6% patients had diabetes, percentages higher than those in the population (statistically significant). Hyperinsulinaemia and resistance to insulin have been implicated in colorectal carcinogenesis.
  
  
  CONCLUSIONS
  As our sample was small, no statistically significant evidence correlating diet and/or physical activity to colorectal cancer has emerged.
