A hamartoma is a benign (non-cancerous) growth made of an abnormal mixture of normal tissues and cells from the area in which it grows. Pulmonary (lung) hamartomas can cause difficulty breathing, coughing up blood, and trigger pneumonia.
Lung metastases are formed by the spread of cancer from other organs to the lung.
A lesion is an abnormality seen on a lung-imaging test. A lung lesion may involve small to large areas of your lung(s), and the severity of the underlying condition may range from relatively minor to life-threatening. These lesions will need further work up to for a diagnosis.
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).
