About 30,000 Americans, and 70,000 people worldwide, are living with cystic fibrosis, caused by inheriting a flawed CF gene from each parent. The disease causes a sticky mucus to build up in the lungs, clogging them and leading to life-threatening infections.
In fact, as recently as the 1960s, most children with cystic fibrosis did not live past preschool age [source: Cystic Fibrosis Canada ]. Moreover, not so long ago in the 1980s, people with cystic fibrosis had an average life expectancy of 14 years.The life expectancy of people with cystic fibrosis has drastically improved over the last three decades.ome statistics, however, report a much more conservative life expectancy estimate of 35 years [source: Disabled World ]. The future seems even brighter for cystic fibrosis patients. The forecasted life expectancy of babies born today is 40 years old [source: Disabled World ].
