Various risk factors are implicated, including excessive estradiol and estrone levels linked to increased risk excessive estradiol risks estrone and cancer growth, hormone replacement therapy (HRT) associated with higher risks HRT risks, pro-inflammatory diets pro-inflammatory diets link, chronic inflammation chronic inflammation role, and sleep disorders like insomnia (HR 1.73) Taiwan sleep study. Protective factors include regular green tea consumption potentially reducing risk per large population studies green tea consumption and healthy lifestyles lowering risk via reduced systemic inflammation according to Zhang et al. (2024) healthy lifestyles mediation. Natural compounds show promise: Rabi and Bishayee (2009) reviewed terpenoids for chemoprevention terpenoids review, Wang et al. detailed silybin's autophagy induction via ROS silybin autophagy, and Karbasforooshan et al. (2019) found topical silymarin prevents radiodermatitis silymarin trial. Treatments include talazoparib for BRCA-mutated advanced cases per Litton et al. (2018) talazoparib treatment. Survivors face challenges like elevated allostatic load in Black women Black survivors allostatic load per Parente et al. (2013), greater physical declines from chemotherapy versus endocrine therapy per Clara Bodelon chemo physical declines, fatigue fatigue studies, and improving psychological outcomes post-treatment longitudinal psych study, with mastectomy linked to higher anxiety mastectomy anxiety. Research highlights bioelectric and epigenetic left-right differences by Masuelli et al. (2022, 2023) left-right differences. Contraindications include hormonal contraceptives and testosterone therapy contraindications TRT contraindication.
