Hall of Fame coach Joe Paterno has a treatable form of lung cancer, his son Scott said Friday. 
  
 Scott Paterno said in a statement his dad was undergoing treatment and that "his doctors are optimistic he will make a full recovery." 
  
 Scott Paterno said the illness was diagnosed during a follow-up visit last weekend for a bronchial illness. 
  
 "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.

 Paterno was fired last week by Penn State with the school engulfed in a scandal involving sex abuse charges against former assistant coach Jerry Sandusky. 
  
 Paterno had announced plans to resign at the end of the season, but the board of regents made the decision to remove him and school president Graham Spanier. 
  
 The NCAA informed Penn State in a letter it will conduct an investigation into the school's actions surrounding the scandal. 
  
 Paterno coached the Nittany Lions for 46 season and led the school to national championship in 1982 and 1986. He is the winningest coach in major college history with 409 victories. 
  
 But his legacy as a coach has come under attack with the allegations against Sandusky, who was his assistant from 1969-99. 
  
 Assistant coach Mike McQueary testified before a grand jury that he witnessed Sandusky engaged in a sex act with a young boy in 2002. McQueary said that he told Paterno about the incident the following day. 
  
 Paterno testified before the grand jury that eventually charged Sandusky with 40 crimes. He said he told athletics director Tim Curley about McQueary's story, but never went to police. Curley is charged with perjury and failure to report a crime. 
  
 "This is a tragedy," Paterno said in a statement when he announced plans to resign at the end of the season. "It is one of the great sorrows of my life. With the benefit of hindsight, I wish I had done more."

 The investigation is being performed following the charges of sexual abuse against former assistant football coach Jerry Sandusky. 
  
 "I am writing to notify you that the NCAA will examine Penn State's exercise of institutional control over its intercollegiate athletics programs, as well as the actions, and inactions, of relevant responsible personnel," Emmert said in the letter. 
  
 The letter, addressed to Penn State President Rodney Erickson, said university officials should be ready to answer questions as part of the NCAA investigation. 
  
 The NCAA investigation comes at a time when others are looking for more answers, which Emmert acknowledged. 
  
 "We recognize that there are ongoing federal and state investigations and the NCAA does not intend to interfere with those probes," he said. |||||
