Association between alcohol consumption and breast cancer incidence and prognosis: A systematic review and meta-analysis

Key Points

• Alcohol consumption is linked to a higher risk of breast cancer, especially in a dose-dependent manner.
• Among over 2.5 million women studied, the risk of breast cancer rose with increased alcohol intake.
• This systematic review and meta-analysis examined data from various studies to establish the association.
• Results indicate that while alcohol increases incidence, it does not appear to negatively affect prognosis in breast cancer patients.
