Exploring the Interplay of Adiposity, Ethnicity, and Hormone Receptor Profiles in Breast Cancer Subtypes

TL;DR

This study investigates how obesity and ethnicity influence the development and prognosis of Luminal breast cancer subtypes, emphasizing biological and social factors to improve risk assessment and reduce disparities.

Contribution

It provides new insights into the combined impact of adiposity and ethnicity on breast cancer subtypes using large-scale epidemiological data and advanced statistical methods.

Findings

Obesity and racial background are significant predictors of Luminal B breast cancer risk.

Biological factors like estrogen metabolism and inflammation are linked to cancer subtypes.

Social determinants such as healthcare access influence cancer disparities.

Abstract

This study explores how obesity and race jointly influence the development and prognosis of Luminal subtypes of breast cancer, with a focus on distinguishing Luminal A from the more aggressive Luminal B tumors. Drawing on large-scale epidemiological data and employing statistical approaches such as logistic regression and mediation analysis, the research examines biological factors like estrogen metabolism, adipokines, and chronic inflammation alongside social determinants including healthcare access, socioeconomic status, and cultural attitudes toward body weight. The findings reveal that both obesity and racial background are significant predictors of risk for Luminal B breast cancers. The study highlights the need for a dual approach that combines medical treatment with targeted social interventions aimed at reducing disparities. These insights can improve individualized risk assessments, guide tailored screening programs, and support policies that address the heightened cancer burden experienced by marginalized communities.
