When Kevin Przybyl of Orlando was born with cystic fibrosis 30 years ago, his doctors predicted he would not live past age 13. Today, he is married, raising a son and running a bass fishing guide business.
 
ABCNews.com features Przybyl in a story today about the growing number of people with CF living into adulthood and beyond, thanks to advancements in treatments and care.

Data gathered by the Cystic Fibrosis Foundation, the story says, shows that a decade ago, only 35 percent of people with CF reached at least age 18. Today, that number has grown to 47 percent.
 
Further, researchers are now developing therapies aimed at correcting the underlying cause of cystic fibrosis.

"If we can get therapies that treat the function and basic defect of the disease, that's a game changer," said Dr. Bruce Marshall, vice president of clinical affairs at the Cystic Fibrosis Foundation. "We'd see people are dying with CF rather than from CF."
