Medical alcohol in normal amounts is not carcinogenic, but prolonged overexposure to medical alcohol is carcinogenic.
Medical alcohol is usually a disinfection product, such as for skin disinfection, preoperative disinfection, physical cooling, etc., the concentration is usually 75%, most of which is used for disinfection of the skin, because of less dosage for external use and shorter time of use, and there is a certain amount of evaporation of alcohol, and the amount of alcohol that enters into the human body is very small, so it generally does not harm the human body and is not carcinogenic.
Prolonged or excessive exposure to alcohol, alcohol can enter the cell body through the cell membrane, so that the protein denaturation, resulting in genetic mutation, may cause cancer, but the probability of cancer is low.
Although alcohol has a certain degree of carcinogenicity, but the normal application of medical alcohol, generally not carcinogenic, can be used with confidence.
