Smoking is not recommended for esophageal cancer patients. Cigarettes contain nicotine, tar and other irritating substances, which are not conducive to the recovery of esophageal cancer patients. Smoking is harmful to health, so it is recommended to quit smoking as soon as possible. Cigarettes contain nicotine, tar and other irritating substances, and the tar in inhaled cigarettes may be deposited in the throat and trachea, causing symptoms such as localized cough and irritating pain. Especially for esophageal cancer patients, if they smoke during the period of illness, it will cause irritation to the throat area, which may aggravate the symptoms of dyspnea, cough and difficulty in swallowing during the period of illness, which is not conducive to the recovery of the disease. It is recommended that esophageal cancer patients should take treatment under the guidance of professional oncologists, maintain a light diet during the treatment period, quit smoking and limit sugar, avoid intake of alcohol and other stimulating foods to alleviate the clinical symptoms and promote the recovery of the body.
