10-year-old boy from Grass Lake smashes his 3-D printed tumor

Ten-year-old Casey Doyle from Grass Lake has been on a four-month mission to “beat Boris,” his nickname for the life-threatening tumor in his throat.

Recently, he did — almost literally.

The fifth-grader took a wooden mallet to a 3-D printed model of Boris, the nearly golf-ball-sized tumor doctors found in January when Casey was diagnosed with synovial cell sarcoma. Donning a Batman shirt in his room at University of Michigan’s C.S. Mott Children’s Hospital, he pounded the exact replica of the villain until it burst into pieces and oozed goo.

A couple of weeks later, Casey was able to bid Boris another goodbye, this time sharing the experience with a crowd of cheering classmates at George Long Elementary who have been supporting their friend with “beat Boris” bracelets.
