STATE COLLEGE, Pa. (AP) — Former Penn State coach Joe Paterno has a treatable form of lung cancer, according to his son.

Scott Paterno said in a statement provided to The Associated Press by a family representative on Friday that the 84-year-old Joe Paterno is undergoing treatment and that "his doctors are optimistic he will make a full recovery."

"As everyone can appreciate, this is a deeply personal matter for my parents, and we simply ask that his privacy be respected as he proceeds with treatment," Scott Paterno said in a brief statement.

The announcement came less than an hour after Penn State said the NCAA would examine how school officials handled a child sex abuse scandal that shocked the campus and cost Paterno a job he held 46 years.

Scott Paterno said the diagnosis was made during a follow-up visit last weekend for a bronchial illness.
