Cryoablation Therapy Freezes Breast Cancer Tumors. I don't know if this link came over but if the little video on my friends facebook page ported over, the video says that they inject liquid nitrogen into the tumor , killing the tumor. Then the body's immune system detects the dead necrotic tissue and simply eliminates it from the body? Crypablation , ??? Hmm, sounds plausible . What say you guys and gals of DVland?
