While there is some evidence to suggest that certain types of alcohol, such as red wine, may contain compounds that have anti-cancer properties, there is no evidence to suggest that alcohol consumption or application can kill cancer cells.

In fact, excessive alcohol consumption has been linked to an increased risk of several types of cancer, including breast, liver, and esophageal cancer, among others. While the exact mechanisms by which alcohol consumption may increase cancer risk are not fully understood, it is thought that the toxic byproducts of alcohol metabolism may damage DNA and other cellular structures, leading to mutations and other changes that can promote the development of cancer cells.

While there is ongoing research into the potential anti-cancer properties of certain compounds found in alcohol, it is not recommended that individuals consume alcohol as a treatment for cancer or as a means of reducing cancer risk. The best ways to reduce cancer risk include maintaining a healthy diet, engaging in regular physical activity, avoiding tobacco use, and following other healthy lifestyle habits.
