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.
Dr. Midthun explains that lung nodules are common and usually noncancerous. They are typically scars that result from a prior infection, such as histoplasmosis or coccidiodomycosis. A CT scan of the chest reveals one or more tiny nodules in many cases. These nodules look white because they are denser than the surrounding lung, which contains air and appears darker.
