Abstract

The rates of obesity are increasing worldwide and this condition is now recognized as a leading preventable cause of cancer. Several diseases are directly related to obesity, including diabetes, hypertension, atherosclerosis, stroke, musculoskeletal disorders, and a diverse range of malignances—such as breast cancer. Obesity is associated with an increased risk of postmenopausal estrogen receptor-positive breast cancer and worse cancer-related outcomes for all breast tumor subtypes. Several mechanisms have been proposed to contribute to the obesity-cancer link, including high levels of circulating and local estrogens, altered amounts of adipokines (leptin and adiponectin), disrupted insulin/IGF signaling, modifications within the microbiome, and local and systemic effects of inflammation. Here we will review recent advances in our understanding of the complex signaling pathways underlying the obesity-cancer link. An improved understanding of these processes is anticipated to propel novel and effective intervention strategies to reduce the global obesity-cancer burden.

    •• Carter JM, Hoskin TL, Pena MA, Brahmbhatt R, Winham SJ, Frost MH, et al. Macrophagic “crown-like structures” are associated with an increased risk of breast cancer in benign breast disease. Cancer Prev Res. 2017;  https://doi.org/10.1158/1940-6207.capr-17-0245. This is the first study to demonstrate that breast white adipose tissue inflammation is associated with breast cancer risk. Breast white adipose tissue inflammation was more prevalent in women with benign breast disease versus normal tissue donors. Among women with benign breast disease, the severity of breast white adipose tissue inflammation was higher in women who went on to develop breast cancer versus those who did not develop cancer.

Cancer Prev Res (Phila). 2017;10(4):235–43.  https://doi.org/10.1158/1940-6207.CAPR-16-0314. In this study, a subclinical inflammatory state was identified in a subset of women with normal body mass index. Women with normal BMI and breast white adipose tissue inflammation had elevated levels of aromatase in the breast and systemic metabolic dysfunction compared to women without inflammation. These findings indicate that anthropometric indices such as BMI fail to identify some women with metabolic obesity and breast inflammation which can predispose to the development of breast cancer.
