Sarcoidosis is a disease characterized by the growth of tiny collections of inflammatory cells (granulomas) in any part of your body — most commonly the lungs and lymph nodes.
“Tumor” simply means an abnormal buildup of tissue that occurs when cells divide too quickly or do not die off as they normally should. A lung tumor is a tumor that occurs in the lung tissue itself or in the airways that lead to the lungs. Lung tumors can be either cancerous (malignant) or benign (non-cancerous).
