Thyroid cancer is usually treated mainly by surgery, and after surgery, chemotherapy or radiotherapy can be supplemented to minimize the recurrence rate and improve the survival rate. If patients still need to receive radiotherapy, chemotherapy, or iodine-131 therapy after surgery, they may need to reduce the consumption of iodine-containing foods such as kelp, shrimp, and iodized salt. In addition, during the recovery period just after thyroid surgery, you should pay attention to a light diet and avoid or reduce the consumption of spicy, stimulating, indigestible and cold foods such as onion, ginger, garlic, chili, fried foods and cakes and desserts. Because the patient’s body is weak and exercise is reduced after surgery, such food will produce a greater burden on the gastrointestinal tract, which is not conducive to the recovery of the body. After the recovery period is over, there is no food that needs to be avoided for life, and thyroid disease itself is a consuming disease that consumes a lot of body functions and nutrition. Therefore, it is recommended to eat more nutritious foods such as meat, eggs, milk, vegetables and fruits to replenish energy and promote recovery. There is no contraindication to the choice of specific foods, just pay attention to the variety of diet and scientific and healthy. At the same time, pay attention to actively cooperate with treatment. The earlier the cancer stage is diagnosed, the earlier the cooperation with treatment, the higher the survival rate of patients and the longer the survival time.
