The Correlation between IL-1β-C31T Gene Polymorphism and Susceptibility to Breast Cancer.

The IL-1β-C31T polymorphism affects breast cancer susceptibility, especially in women with late age at first birth, high BMI, postmenopausal status, negative smoking history, and invasive ductal carcinoma. Our study adds to the evidence about the importance of IL-1β-C31T polymorphism in breast cancer susceptibility.
