What is cystic fibrosis exactly?

What is cystic fibrosis exactly?

Inherited disease: Cystic fibrosis (CF) is an inherited disease that affects the cells lining the lungs, sinuses, intestines, spleen and liver.

Medications can help; in late-stage disease, lung transplantation may be life-saving. ...Read more
