Alcohol is believed to act as a chemical irritant to sensitive cells and triggers DNA damage. Besides alcohol also acts as a solvent for other carcinogens, such as those found in cigarettes, so the carcinogens that can enter cells more easily.
Alcohol is also thought to affect important hormones, such as estrogen thus increasing the risk of breast cancer.
