answer:“The two major risks associated with fluoroscopy are * radiation-induced injuries to the skin and underlying tissues (“burns”), and * the small possibility of developing a radiation-induced cancer some time later in life. When an individual has a medical need, the benefit of fluoroscopy far exceeds the small cancer risk associated with the procedure. Even when fluoroscopy is medically necessary, it should use the lowest possible exposure for the shortest possible time.” FDA Good luck, John. I wish you less back pain.
