Gwen Ifill has died
tangential question, may be there is some doctor here who can explain - i'm not a doctor and just from pure technical/mechanical point of view i don't understand why for example we can't just insert 2 thin, needle thin like,  probes (similar to laparoscopy only much thinner and more flexible), one with video camera and LED and one with IR laser, ultrasound guide it to the tumor and burn the tumor small piece by small piece. Wouldn't it be better than radiation for example?
