Culture Media â 1 CULTURE MEDIA AND CULTIVATION OF BACTERIA The study of microorganisms requires techniques for isolating cells from natural sources and growing them in the laboratory on synthetic media. Thus, development of synthetic culture media and culture techniques have played important roles in the advancement of this field. Microbiologists
Im looking for advice/reassurance. A recent ct scan shows 4 and 5 mm modules, one in lower lobe of each lung. I have a rescan in 4 months. What are the chances of these being lung cancer or metastases from elsewhere. Im very worried but I guess if its lung cancer it should be caught early.
Answers from Edward C. Rosenow III, M.D. Yes, lung nodules can be cancerous, though most lung nodules are noncancerous (benign). Lung nodules â small masses of tissue in the lung â are quite common. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size.
