Thyroid malignant grade 4 is not cancer

Thyroid nodules grade 4

include 4A, 4B and 4C. If it is 4A nodule, it indicates that there is a tendency of mild malignant lesions, but it generally does not become cancer when daily attention is paid. The malignant possibility of 4B is relatively increased, but some nodules will not become malignant at the time of control. If it is thyroid nodule grade 4C, it indicates that the possibility of malignancy is further increased. If the nodule is large and poorly differentiated, it is generally cancer. Patients can follow the doctor's advice for fine needle aspiration cytology, which is helpful to further evaluate the benign and malignant thyroid nodules.
