There is no connection between the development of skin cancer and diet, so there is no dietary contraindication for skin cancer patients. However, most skin cancer patients are elderly people, and such patients may have age-related diseases, such as hypertension, diabetes and hyperlipidemia. It is recommended to follow a regular healthy lifestyle, including less alcohol consumption, light diet, attention to rest, less intake of high-fat, high-protein and high-sugar foods, as well as prevention of various age-related diseases to keep the body in a relatively healthy state, which is conducive to the treatment and prevention of skin cancer.
