Answer:
30 years
Explanation:
Before the 1980s, about half of the people with CF did not live into their 20s. However, over the past few decades, life expectancy for people with this condition has improved dramatically.
Year of birth Median predicted survival age
1993–1997 31
2003–2007 37
2013–2017 44
Better treatment methods developed over the past 20 years have increased the average lifespan of CF patients to nearly 30 years.
Between the 1970s and 1990s, life expectancy gradually increased to age 31, thanks to still more treatments, including lung transplants and DNase.
As a result of improved and better treatment, the life span of people with cystic fibrosis have increased during the 31-period by approximately 30 years.
Cystic fibrosis (CF) is a disorder that is hereditary. It is characterized by severe lungs, digestive system damage as well as damage to other organs of the human body.
People who had cystic fibrosis before 1980 had their life expectancy pegged around their 20s.
However, in recent years, better treatment have been developed which has increased the life span of people with cystic fibrosis by approximately 30 years.
