Research shows that even moderate alcohol consumption increases the risk of several types of cancer, including cancer of the breast, oral cavity, pharynx, esophagus, liver, larynx, colon, and rectum[2][4][7]. The risk increases with the amount and frequency of drinking, with just one standard dose of alcohol per day significantly increasing the risk, particularly in women, where the risk of breast cancer is increased by approximately 19%[5]. Alcohol is metabolized in the body to acetaldehyde, which damages DNA and promotes the formation of cancer mutations[2][4]. In addition, alcohol increases the levels of hormones such as estrogen, which contributes to the development of breast cancer[4]. The risk varies according to genetic predispositions, lifestyle, obesity and socioeconomic status[1]. Studies also show gender differences, with women generally more vulnerable to the carcinogenic effects of alcohol[3][5]. In Europe, breast cancer accounts for up to 66% of alcohol-related oncological diseases[4]. Researchers emphasize the need for better public awareness and restriction of alcohol consumption as cancer prevention[2][6].
