Will needle biopsy cause the tumor to spread?

Needle biopsy will not cause the spread of the tumor. Needle biopsy is a minimally invasive operation that will not cause the rupture of the tumor and expose it to irrelevant blood vessels, nor will it increase the pressure inside the tumor to stimulate new tumor cells.

In some patients, new metastases appeared within a short period of time after needle biopsy, which should have been metastasized by tumor cells through the inherent vasculature inside the tumor, not triggered by the needle biopsy operation.

There is also a theory that the needle biopsy may cause tumor metastasis in the needle path of the puncture needle, but it can be avoided as long as the operation is standard. The standard operation requires the puncture needle and the biopsy needle to be separated, and the puncture loop needle punctures the tumor body. Fix, and then isolate the needle track from adjacent normal tissues. Biopsy needle biopsy is performed in a trocar. The tumor tissue is obtained and removed from the trocar. After the biopsy is completed, the trocar can be pulled out to avoid biopsy tissue planting In the needle road.
