Papillary microcarcinoma of the thyroid refers to papillary carcinoma of the thyroid less than 1 cm in diameter, which is usually more insidious and is mostly found incidentally. Papillary microcarcinoma can metastasize to lymph nodes in the neck, with a probability ranging from 2% to 40%; distant metastases, such as bone and lung metastases, can also occur, but are less common.
Papillary microcarcinoma often requires ultrasound to detect because it has no obvious clinical symptoms, so it is important to have regular ultrasound examinations of the thyroid. The prevention and treatment of tumors lies in early detection, early diagnosis, and early treatment. Only timely detection and treatment in the early stages of tumors can achieve better treatment results.
