thanks for asking I had a PET scan and I have lung cancer. the cancer is stage 1 and is approx. the size of my fingernail. there will be only 5 treatments with a new radiation that kills very few good cells. hoping 4 the best.A PET SCAN IS THE ONLY WAY TO CHECK FOR CANCER AND SEE IT LIGHT UP BECOUSE OF THE ATOMIC SUGAR. WONDERFULL INVENTION. GET ONE TODAY NOT TOMARROW.
