He nicknamed it after Frankenstein’s monster. Frank the Tumor gained national attention when David’s mother created “Frank Must Die” bumper stickers, which the family auctioned on eBay to defray medical costs. Chemotherapy and radiation treatments shrank it to the size of a peach pit, and in February 2005 an operation was performed to remove the rest. Biopsies and MRI scans concluded that the boy’s brain is now cancer-free, said Dr. Hrayr Shahinian of the Skull Base Institute in Los Angeles. Frank the Tumor is gone and the 11-year-old Virginia boy who named his dangerous foe after the Frankenstein monster proudly showed off karate kicks Thursday and chattered about school even though he still suffers effects of his therapy. David Dingman-Grover, whose battle with Frank drew national concern, got a clean bill of health from the surgeon who removed the cancerous mass a year ago. “I feel great,” David said. “After it just went away, I was just, like, so proud, and I was happy because a lot of people I knew were really scared for me.” “I don’t think about it at all. I think about mostly, like, just getting on with my life, getting on with the next day,” he said.
