Passage 1: Terry Fox was born on July 28, 1958, and grew up in Port Coquitlam, British Columbia. Throughout his school years, he was active in sports. He loved basketball, and although he was too short to qualify for the school team in Grade 8, hard work and persistence earned him a place the following year. In Grade 12, he and his best friend received their high school's Athlete of the Year award. Terry wanted to become a Physical Education teacher, and after graduating from high school in 1977, he began studying kinesiology at Simon Fraser University in Burnaby. In December 1976, Terry experienced sharp pain in his right knee. By March of the following year, the pain had become so severe that he went to the hospital, where he was diagnosed with osteosarcoma. This aggressive form of bone cancer is the sixth most common cancer among children; it particularly afflicts teenage boys. Terry's right leg was amputated 15 centimeters above the knee, and he underwent chemotherapy. Doctors gave him a 50 percent chance of survival. After treatment, Terry made rapid progress as a result of his positive thinking and the same determination that had served him in school. Three weeks after the amputation, he was walking with a prosthetic limb and playing golf with his father. His experiences during the 16 months at the British Columbia Cancer Control Agency facility, however, left their mark on Terry. Watching other young cancer patients suffer and die awakened a deep compassion in him, and he made it his personal mission to raise awareness and funds for cancer research.
