A tumor cannot grow without a blood or nutrient supply. It is believed that a tumor mass cannot exist in a volume greater than the tip of a ballpoint pen without a proper blood or nutrient supply.
An Embolization procedure is the process of inserting a thin tube, the diameter size of a spaghetti noodle, called a catheter, into the artery to discover the blood vessels feeding the tumor. Then a small amount of a chemotherapy or immunotherapy drug is dispensed directly into the blood vessels feeding the tumor. This is followed by placing small blocking particles into those same blood vessels, closing off the blood supply. Finally, platinum coils are inserted to lock the door.
This procedure can be performed multiple times to achieve the desired response within the tumor. The goal is to create a chronic dormant state and to shrink the tumor.
Three to four weeks after Embolization, the second step, Cryoablation occurs.
