Thyroid follicular carcinoma, like papillary carcinoma, should have no feeling or symptoms in the early stage, and most of these patients are found because of census or physical examination. Most of these patients are found during screening or physical examination. Patients generally do not have any discomfort, that is, all of them are symptomatic, and some of them may have psychological symptoms. Or when accompanying other people, when they feel uncomfortable and come for checkup, it is often because this patient has other problems, such as pharyngitis or lymphadenitis, and only when they come for checkup they find out the follicular carcinoma of thyroid, but this symptom has nothing to do with the symptom of follicular carcinoma of thyroid itself. So early follicular carcinoma should not feel or have any symptoms.
