type 2 diabetes associated with er breast cancer in black women

According to a new study, the odds of breast cancer may be increased due to incidence of type 2 diabetes among Black women in the U.S. Around 54,000 black women were studied, who did not have cancer at the beginning of the study. In the period of next 18 years, around 900 women were found to have estrogen receptor positive (ER+) breast cancer and 460 women were diagnosed with estrogen receptor negative (ER-) breast cancer.

Women with type 2 diabetes had 43% more chances of developing ER- breast cancer, which is an aggressive type of cancer, present twice as commonly in U.S Black women as compared to White women.

According to the study author, Julie Palmer, the reason for increase in risk of ER- breast cancer with diabetes is inflammation due to chronic diabetes that triggers cancer.

Additionally, Palmer said that diabetes is twice as common in African American than in the Whites. This explains higher prevalence of ER- breast cancer in Black women.
