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.
That's because benign lung nodules grow slowly, if at all. On the other hand, cancerous nodules, on average, double in size every four months. Your doctor may continue to a check your lung nodule each year for up to five years to ensure that it is benign. Hamartomas are the most common type of benign lung tumor and the third most common cause of solitary pulmonary nodules. 2  These firm marble-like tumors are made up of tissue from the lung's lining as well as tissue such as fat and cartilage.
