The life expectancy of cystic fibrosis patients has been increasing over the past 40 years. In the 1980s life expectancy of people with cystic fibrosis was 14 years. 10 years back, the life expectancy of a person with cystic fibrosis was around 18 years. Today it is 35 years. The median life expectancy of a newborn with cystic fibrosis has increased from 4 years to 32 years. It has been estimated that there has been more than 10 year increase in the average life expectancy of affected people in North America. Over 90% of the affected infants now survive beyond one year.
Kathrine Shores was apparently one individual who lived to 79. http://home.donaldshores.com:22/Newspape... There are rumours of an 84 year old CF patient that is seen at a CF Clinic in New Mexico http://www3.nbnet.nb.ca/normap/remarkabl... The oldest person with CF was 76 years of age. I was on a website that said the oldest person to have cystic fibrosis was a man who was 88. Just type in your question on google and it will take you to the website. There is probably a Cystic fibrosis association in your area - Look it up in the phone book or ask at a local clinic.
