What is a needle biopsy needle

With the continuous improvement of examination techniques, the accuracy rate of tumor diagnosis has gradually increased, but there are still a large part of tumors do not have typical imaging characteristics, so it is difficult to diagnose. Correct diagnosis requires the combination of clinical, imaging and pathological diagnosis, among which pathological diagnosis plays a crucial role in the overall treatment choice.

"For tumors, pathological diagnosis is the universally accepted diagnostic standard, and there is no diagnostic method that can be more accurate than pathological biopsy," Yang said. "Needle biopsy is a type of pathological diagnosis, and its purpose is to confirm the diagnosis. Because needle biopsy takes pathological tissue directly from the patient, if you can intuitively find the tumor cells, you can confirm the tumor disease."
