For patients with thyroid cancer, it is possible to eat mastic. However, you should pay attention to the appropriate amount to avoid stomach discomfort, which may affect your diet. For post-operative thyroid cancer patients, you can eat iodine-rich foods such as seaweed and nori in moderation. Especially for patients who need iodine 131 treatment, they should avoid iodine-rich foods during the 2 weeks of treatment and therapy, especially they should be given iodine-free diet. For patients after thyroid cancer surgery, they should eat more high protein, high vitamin and high calorie foods to promote wound recovery and organism healing. In daily life, you can eat more kiwi to help dissipate the nodules; more asparagus, which has an anti-cancer effect; more mushrooms and fungus to strengthen your immunity and resistance; and more soybeans, yams and other foods that strengthen the spleen and promote water retention.
