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.
A: Lung nodules are spots on the chest that are 3 cm or less. If the diameter is more than 3 cm it is characterized as lung mass. For a nodule to be detected by an x-ray it has to be at least 1 cm in size.A CT scan is more detailed as compared to an x-ray and it can show give much more information about a nodule.: Yes, the size of lung nodules is a major determining factor whether the lung nodules, showing up as small, circular shadows on an X-Ray, represent a cancerous growth. If these shapes are less than 25 mm or 1 inch across, then they are no major cause for concern.
