The Role of Oxidative Stress in Breast Cancer


Book Section

Breast cancer is the most common cancer in women worldwide and it accounts for the second highest morbidity and mortality. Disease etiology and progression is multifactorial and several risk factors associated with breast cancer exert their effects by modulation of oxidative stress status in the cells. Oxidative stress occurs due to an imbalance between reactive species and antioxidant defenses in the cells. Excess reactive species are deleterious in normal cells, while in cancer cells, they can lead to accelerated growth and survival correlating with an aggressive and therapy-resistant phenotype. Specifically, risk factors and their effect on the oxidative stress response are associated with breast cancer development, progression, and treatment outcome.This chapter provides a review of the accepted concepts, recent findings, and limitations in the understanding of the cross-talk between antioxidant capacity, redox-sensitive transcription factors, and cell survival/death signaling in oxidative stress response and redox adaptation in breast cancer. Addressing these matters and identifying pathway dysregulation is required for a rational basis to improve the design of redox-related therapeutics and clinical trials in breast cancer. © 2014 Elsevier Inc.
