Paterno Has Lung Cancer, Son Reveals
Recently fired Penn State football coach Joe Paterno has lung cancer, his son wrote Friday in a statement provided to the Associated Press.
Joe Paterno, 84, is being treated and "his doctors are optimistic he will make a full recovery," his son, Scott, wrote.
"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's statement said.
The diagnosis, according to the statement, was made at a doctor's visit last weekend -- originally a follow-up appointment for a bronchial illness, the AP reported.
Joe Paterno was fired last week amid allegations about former Penn State defensive coordinator Jerry Sandusky, who has been charged with sexually assaulting eight boys during a 15-year period.

Former NFL Players Taking Part in Brain Disease Study
Researchers have started testing retired professional football players in an attempt to learn how to diagnose a degenerative brain disease in former athletes while they are still alive.
Currently, the only way to confirm Chronic Traumatic Encephalopathy (CTE) is by examining brains after death, the Associated Press reported.
The researchers at Boston University's Center for the Study of Traumatic Encephalopathy plan to compare 100 retired NFL players with 50 retired elite athletes from non-contact sports.
Participants undergo two days of examinations that includes brain scans, a spinal tap, neurological and cognitive tests, blood work and a psychiatric interview, the AP reported.
Until CTE can be diagnosed while athletes are still alive, it's impossible to develop treatments or learn how to prevent it, said center co-director Robert Stern.
