DENVER (AP) -- With no basketball to coach, George Karl is tending to his other passion in life: fighting cancer, a disease he's beaten twice.
The Denver Nuggets coach lent his voice Tuesday to the American Cancer Society and Quest Diagnostics, which are teaming up on a nationwide cancer prevention study. It aims to follow 300,000 people for 20 to 30 years to see how genetics, lifestyle and the environment affect cancer risk.
Karl is 21 months removed from a brutal battle with neck cancer, which came a few years after he beat prostate cancer. His son, Coby, is a survivor of lymph node cancer.
Karl said he's spending his spare time during the NBA labor impasse speaking at cancer charities and encouraging people to join the fight against the disease.
