Vegetables you usually can’t eat after nail cancer surgery include kelp, nori, and vegetables and fruits that can cause allergies. Seaweed foods such as kelp and nori contain high concentration of iodine. As high iodine diet may lead to thyroid cancer, nail cancer patients avoid eating kelp after surgery, or it will easily trigger the rebound of the disease. Some patients are allergic to certain vegetables or fruits, which will lead to allergic reactions and various discomforts in the body. For example, many people are allergic to certain tropical fruits, such as mango, durian, pineapple, etc. Consumption of these fruits may lead to edema in the throat, affecting breathing, and there may be manifestations of pressure on the surgical area of thyroid cancer. Thyroid cancer patients are advised to go to the hospital for regular checkups, and patients should pay attention to a light, low-iodine diet after surgery.
