“Sarcoidosis can occur in any organ, but it most commonly affects the lungs, lymph nodes and heart. Signs and symptoms of sarcoidosis vary depending on which organs are affected. Doctors don’t know the exact cause of sarcoidosis.  While anyone can develop sarcoidosis, factors that may increase your risk include: age, sex, race and family history. Sometimes sarcoidosis causes long-term problems.  Complications depend on the organ effected.”
