As Quinn Waters, also known as "The Mighty Quinn," prepares to celebrate his fifth birthday on Feb. 10, he is also preparing for another battle against cancer.
The Quincy Fire Department and Brewster Ambulance Service cheered on the son of Officer Tara Waters as they wished him a happy birthday, the Quincy Police Department tweeted.
Quinn was diagnosed with a medulloblastoma, a tumor on the brain stem, in 2019 according to a Facebook page in his name.
Quinn's treatment left him with a weakened immune system which forced him into an approximately 100 day isolation period in 2019.
Quinn will now be undergoing chemotherapy and radiation, according to the tweet.
His family is advocating for blood and platelet donations on his Facebook page following his diagnosis.
