“Sarcoidosis is a rare disease. The Foundation for Sarcoidosis Research estimates that there are fewer than 200,000 cases per year in the United States. African-Americans are three times more likely to be diagnosed with sarcoidosis than Caucasians and tend to have more severe disease. This disease causes clusters of immune cells called granulomas to infiltrate your organs and lymph nodes. Sarcoidosis most commonly affects your lungs, but it can affect any organ in your body.”
