    Minimally Invasive Transanal Endoscopic Microsurgery (TEM) Rules Out Cancer

    Earlier today Dr. Hueylan Chern called me to let me know that I don’t have cancer and that the transanal endoscopic microsurgical (TEM) excision procedure was a success. I really don’t know how to say ‘Thank You’ in a way that relays my true emotions. Obviously, I’m ecstatic and my family is also.
