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.
Lung nodules are quite common, and are found on 1 in 500 chest x-rays, and 1 in 100 CT scans of the chest. Approximately 150,000 lung nodules are detected in people in the United States each year. Roughly half of smokers over the age of 50 will have nodules on a CT scan of their chest. lung nodule is defined as a âspotâ on the lung that is 3 cm (about 1Â½ inches) in diameter or less. If an abnormality is seen on an x-ray of the lungs that is larger than 3 cm, it is considered a âlung massâ instead of a nodule.
