Relationship between body mass index and incidence of breast cancer

To investigate the relationship between body mass index (BMI) and the breast cancer incidence, so as to making contribution to breast cancer screening in high-risk groups, to adjustment from passive medical treatment to active treatment Methods: BMI status of 206 breast cancer patients and that of 210 healthy subjects at different ages were compared and analyzed.

The mean BMI was significantly higher in breast cancer patients than in healthy subjects 24.45±3.50 vs. 23.80±3.10 kg/m(2), t=-2.189, P=0.001. When stratified by age, BMI were significantly higher in ≥60 age for breast cancer than that of control group (Z=-3.408, P=0.001) and no significant difference in <60 years old .Logistic regression analysis showed that BMI was a risk factor of breast cancer (OR=1.886, 95% CI: 1.122-3.009).

BMI have a relationship with the occurrence of breast cancer, especially for ≥60 years old.
