Unveiling the intricate dance: Obesity and TNBC connection examined

Amid the dynamic field of cancer research, various targeted therapies have proven crucial in combating breast cancer, the most prevalent cancer among women globally. Triple Negative Breast Cancer (TNBC) stands out from other types of breast cancer due to the absence of three key receptors on the cell surface (progesterone, estrogen, and HER2). Researchers are working on finding ways to address TNBC's elusive biomarkers and minimize the damage caused by the disease through treatments like chemotherapies and targeted pathway receptors. One connection that should receive more attention is the link between TNBC and obesity. Obesity is defined as consuming significantly more energy than is expended, resulting in a high BMI. Moreover, obesity fosters a cancer-friendly environment characterized by inflammation, elevated levels of hormones, proteins, and signaling that activate pathways promoting cancer. Non-Hispanic black women have experienced notable disparities in TNBC rates. Various factors have led to the higher incidence and poorer outcomes of TNBC in non-Hispanic black women. This detailed review explores the complex relationship between obesity and TNBC, examining how the two disorders are connected in terms of disparities and offering a glimpse into future research and interventions. •Obesity and TNBC are well-known links. This review article discusses Leptin, JAK/STAT, ERK/MAPK, and P13K/AKT/mTOR to examine molecules that promote obesity and TNBC.•This study explores how socioeconomic status, healthcare access, cultural practices, and screening techniques affect obesity, a key TNBC risk factor.
