Breast cancer is more likely to occur in women who drink alcohol than in those who avoid alcoholic beverages.

This study examined the correlation between light, moderate, and heavy consumption of alcohol and breast cancer risk by meta-analysis. 38 epidemiological studies were included in this meta-analysis.

Researchers observed that generous intake of alcohol elevated breast cancer development risk. Daily consumption of alcohol was found to increase the risk of developing breast carcinoma by 11% in this study. The findings of this study suggest that light, moderate, and heavy drinking of alcohol may be a major contributing factor to the development of breast cancer in women.
