Why does alcohol increase the risk of breast cancer?

Professor Rafał Stec confirms that alcohol and nicotine increase the risk of various cancers, including head and neck cancers. Alcohol contributes to at least seven types of cancer, including breast cancer, with only 15% of respondents aware of this link. Studies show that alcohol consumption is linked to cancers of the mouth, throat, and liver. Abstaining from alcohol can improve treatment outcomes for breast cancer patients. Research indicates that even moderate drinking raises cancer risks, with the IARC classifying alcohol as a major carcinogen. The European Code Against Cancer recommends avoiding alcohol altogether. Recent studies suggest that the cancer risk from drinking is comparable to smoking a small number of cigarettes weekly.
