Relationship between obesity, breast cancer

Obesity may be associated with early-onset breast cancer in Black women.

In a study, published in JAMA Network Open, investigators recruited 332 Black women and 753 white women who had been diagnosed with breast cancer between 2017 and 2022. At baseline, a greater proportion of the Black women enrolled were classified as obese by body mass index category (61.1%) compared with the white women (39.3%).

The investigators found that the Black women with obesity were more likely to be diagnosed with overall breast cancer, early-onset breast cancer, luminal A subtype breast cancer and triple-negative breast cancer compared with white women.

The investigators hope their findings can lead to strategies to reduce disparities in the diagnosis of breast cancer among Black women.
