CHESTER, N.J. (CBSNewYork) — A local teenager is in the fight of his life against cancer but thanks to a robot, he’s keeping up in school. As CBS2’s Cindy Hsu reported, V-Go the robot has been helping 14-year-old Sabastian Quinn go to school from home as he undergoes treatment for cancer. He was diagnosed just six months ago. “It was during football season and I noticed a big lump on my leg and I thought it was a bruise or something swollen,” Quinn said.
