Thyroid 4a generally refers to thyroid nodule category 4a, which is a classification under ultrasound. Whether or not ablation treatment can be done depends on the patient’s own condition. If it is a malignant thyroid nodule, certain conditions need to be fulfilled before ablation treatment can be considered, while some benign thyroid nodules can be considered for ablation treatment.
Thyroid nodules are lumps that appear due to localized hyperplasia of thyroid cells caused by various reasons. Clinically, they may appear as a lump in front of the neck, move with swallowing, have a foreign body sensation in the pharynx, and some of them may have a hoarse voice or shortness of breath, etc. For some of the benign thyroid nodules, it is possible to treat them with ablation surgery.
Thyroid nodule 4a belongs to the suspected malignant nodule, it is recommended that thyroid puncture biopsy, if it is clear that the malignant thyroid nodule meets the diameter of less than 1cm, does not invade the peritoneum and there is no lymph node metastasis or distant metastasis, etc. can be considered for ablation surgery treatment. When the diameter of malignant nodules is large, ablation may be incomplete, and surgery is recommended to completely remove the lesions.
Patients diagnosed with thyroid nodule 4a are advised to go to the hospital and ask the doctor to determine whether ablation surgery can be performed.
