Whether you can have sex after tongue cancer surgery needs to be judged according to your own recovery situation, and you can have sex appropriately if you have recovered well. If the recovery is good and there is no other uncomfortable reaction, one can have normal sex life. If the condition is serious or the patient is still in the recovery period after the surgery, it is not recommended to have sex in order to avoid local pain or other reactions. Tongue cancer patients need to do good oral hygiene after surgery to avoid postoperative infection. Avoid smoking and alcohol, eat light diet, especially not spicy and stimulating food to avoid postoperative complications. Dietary advice is to supplement high-protein food with vegetables and fruits for balanced nutrition. Participate in outdoor exercise to improve your immunity.
