Patients with thyroid cancer can occasionally eat barbecue, but should limit their intake of such foods. This is because thyroid cancer is a common malignant tumor in the head and neck area, and its exact cause is still unclear. The mechanism of its development is also not clearly understood. However, the high incidence of thyroid cancer is related to certain factors such as radiation, viral infections, or genetic factors, and both iodine deficiency and excess can lead to a high incidence of thyroid cancer. Barbecued foods are not beneficial for the recovery from thyroid cancer, therefore it is clinically advised to reduce intake. However, eating it occasionally does not have a significant impact on the overall health of patients, so it can be consumed in moderation. Additionally, for patients with thyroid cancer, the diet should mainly be easy to digest, non-irritating, and should enhance bodily immune strength.
