Cystic fibrosis is a genetic disorder that affects the secretory glands of the body, resulting in buildups of mucus in vital organs including the lungs, pancreas, intestines, sinuses, reproductive organs and liver. Over time, cysts will also form in affected organ systems, and the presence of a high volume of mucus in areas where it is not supposed to collect gives rise to a greater risk of opportunistic infections. There are varying degrees of severity; mild cases of cystic fibrosis may not present until adolescence, but severe cases will be present at birth. It is a progressive and degenerative condition, but improving treatment methods have improved the long-term prognosis for patients.
