(WHDH) — The Quincy Police Department cheered on the “Mighty Quinn” as he gets ready to start another round of radiation.

Quinn’s family announced last week that an MRI had revealed a new tumor growing on his brain. The heartbreaking discovery comes just one year after tests showed no evidence of new disease.

His family said that Wednesday is Quinn’s fifth birthday and he will have to spend it at Massachusetts General Hospital.

The community has rallied around the little boy throughout his courageous battle with cancer.

He shot hoops with the Harlem Globetrotters and dropped the puck at a Bruins game.

When he was undergoing chemotherapy treatments and unable to leave his home, professional athletes and celebrities like the Dropkick Murphys came to him at the window of his Weymouth home.
