Cystic fibrosis is a genetic disease that affects the lungs and digestive system. It is inherited through a recessive gene, so both parents must carry the gene for a child to be affected. Symptoms include thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections. Treatment involves using an inflatable vest to help clear mucus from the lungs.
