This systematic review of 50 epidemiologic studies examined the association between breast cancer risk and the timing of smoking initiation. Smoking at any age—whether ≤15, 15–20, or ≥20 years—was associated with increased breast cancer risk. Notably, smoking before first childbirth conferred a higher risk than smoking after childbirth. These findings underscore the potential long-term impact of early-life smoking on breast cancer development.
