It has always been my belief that PCa is spread in high gleason tumors as a result of the biopsy. It seems to me that tearing out pieces of tissue with the resulting heavey bleeding could easily spread Pca cells locally. If they are of the hardy variety G8-10. They could easily take hold elsewhere.
I think that that is an erroneous belief. The needle is essentially a hollow tube ------ it goes in and removes a plug from within the gland. Only tissue within the tube is removed and that tissue is one piece attached cell to cell by connective tissue. It's not as though the needle is dropping off bits and pieces as it is withdrawn. Likewise the bleeding. The bleeding occurs from severed minute blood vessels. Think of a clean cut ---- when you have a neat slice there are no bits and pieces dropping off the wound. Despite the claims of some docs who claim this of a biopsy (invariable they have a "less dangerous" test procedure to sell) there has not been one documented case of PCa being spread this way.
