Brain tumor puncture needle is done in the head

It depends on what kind of puncture it is. If it is to measure intracranial pressure, it is not done on the head, but from the lumbar spine, that is, a lumbar puncture. To do a tumor biopsy, of course, a puncture is performed on the head. Part of the tumor tissue can be taken through the biopsy, and then a pathological test can be performed to determine the final tumor nature.
