Bright tumors, dim prospects

... Sept. 13, 2007 -- It doesn't matter how small or large it is, if a cervical tumor glows brightly in a PET scan, it's apt to be more dangerous than dimmer tumors. That's the conclusion of a new study of cervical cancer patients at Washington University School of Medicine in St. Louis. "We've seen that...
