Can mold grow in your lungs?

Mold can grow in the lungs in rare cases, particularly in people with weakened immune systems, chronic lung disease, or preexisting respiratory conditions. When mold spores are inhaled, they can settle in the airways and cause infections such as aspergillosis, which occurs when the Aspergillus fungus grows inside lung tissue. Symptoms may include coughing, chest pain, shortness of breath, and fever. In severe cases, mold growth in the lungs can lead to inflammation, scarring, or long-term breathing problems. Prompt medical evaluation and antifungal treatment are required to control the infection and prevent further respiratory complications.
