What makes breast cancer...

[Gracie Dean]

In 1969, the Chicago Bears were in the midst of a 1-13 season, which was the worst record in the history of the Bears.[3] Piccolo had finally earned a place in the starting lineup as an undersized fullback. During the ninth game in Atlanta on November 16, he voluntarily removed himself from the game, something he had never done, which raised great concern among his teammates and coaches. He had extreme difficulty breathing on the field, so when the team returned to Chicago he was promptly sent for a medical examination, and was diagnosed with embryonal cell carcinoma.[4]

Soon after, Piccolo had surgery at Sloan-Kettering in New York City to remove the tumor. He had another surgery in April 1970 to remove his left lung and pectoral muscle. After being bothered by chest pain, Piccolo was re-admitted to the hospital in early June, and doctors determined the cancer had spread to other organs, most notably his liver. Brian Piccolo died on June 16, 1970, at the age of 26.
