Will puncture cause cancer cell metastasis?

Dr. Dong said that the needle used for tumor puncture is small, and the damage to normal tissues and tumors is minimal. Fine needle aspiration uses suction material, and the sucked cells are hidden in the needle core due to negative pressure suction, which will not leak and contaminate other layers of tissue, and there is no risk of tumor spread. Fine-needle aspiration of thyroid nodules has been used so far, and there is no report of needle tract implantation of tumors, so there is no need to worry that the puncture will cause tumor spread.
