Background And Objective:
Obesity is associated with increased risk of colorectal cancer. Many studies showed that body mass index (BMI) is related to the incidence of colon cancer. This study was to explore the relationship between BMI and colon cancer in Chinese population and provide evidences for the prevention of colon cancer.
Methods:
Clinical data, including BMI, of 707 colon cancer patients and 709 healthy subjects were compared.
Results:
The mean BMI was significantly higher in colon cancer patients than in healthy subjects [(24.52+/-4.56) kg/m2 vs. (23.75+/-3.14) kg/m2, t=-3.72, P<0.001]. When stratified by sex and age, the BMI was always higher in colon cancer patients than in healthy subjects. Logistic regression analyses showed that BMI was an important risk factor of colon cancer (odds ratio=1.059, 95% confidence interval=1.029-1.090).
Conclusion:
The occurrence of colon cancer in Chinese population is related to BMI.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
