Metastatic Carcinoma in Lung Tissue at 40x Magnification

Oftentimes patients with metastases in the lungs have not developed any symptoms of the disease at the time they are diagnosed. Instead, the thorough medical exams and advanced imaging techniques used to diagnose and stage the primary cancer frequently lead to the discovery of pulmonary metastases. In instances of slow growing primary tumors, however, metastases may be noticed before the initial disease. When symptoms of lung cancer metastasis do occur, they are similar to the signs of primary lung cancer and may include a chronic cough, chest pain, and shortness of breath.
