Study Links Drinking More Than Three Alcoholic Beverages Daily to Increased Melanoma Risk
A large American study spanning over 15 years and involving approximately 470,000 participants has found that consuming more than three alcoholic drinks per day is associated with a 17% increased risk of developing melanoma, the deadliest form of skin cancer. The research, published in The Journal of Nutrition, tracked 469,828 individuals who reported their alcohol consumption habits and recorded 5,034 invasive melanoma cases and 3,284 early-stage melanoma cases during the follow-up period.
The study revealed that the risk for invasive melanoma rose by 14%, while early-stage melanoma risk increased by 21% among heavy drinkers compared to non-drinkers. The elevated risk was consistent across all types of alcoholic beverages, including beer, wine, and spirits, with no type deemed safer. However, researchers emphasized that the study is observational and does not prove a direct causal link between alcohol and melanoma.
Moshe Bar-Chaim, CEO of the Israeli Association for the War on Cancer, highlighted that these findings reinforce existing scientific recommendations to avoid alcohol due to its cancer risks, including melanoma. With the summer vacation approaching, the association urged parents to monitor children’s exposure to risk factors such as unprotected sun exposure, alcohol consumption, and smoking. They stressed that sunburns in childhood significantly increase the risk of skin cancer later in life due to cumulative DNA damage.
The association also reminded the public that the most effective protection against melanoma is reducing sun exposure by avoiding peak UV hours, seeking shade, wearing wide-brimmed hats and protective clothing, and regularly applying sunscreen with SPF 30 or higher. They estimate that in 2026, around 2,130 Israelis will be diagnosed with malignant melanoma, with 92% detected early, improving recovery chances. Despite awareness campaigns, about 30% of Israeli youth still frequently sunbathe, often valuing tanned skin for aesthetic reasons, which remains a concern for health professionals.
Summary: A 15-year US study of nearly 470,000 people links drinking more than three alcoholic beverages daily to a 17% higher risk of melanoma. Israeli cancer experts warn parents to limit children’s alcohol use and sun exposure ahead of summer, emphasizing prevention measures against skin cancer.
