If you are measuring doses from vials, do not reuse needles and syringes. If you are using the cartridges or pens, use a new needle each time. Learn how to discard needles and medical supplies safely. Consult your pharmacist for more information.
1 Pulmonary nodules appear in about one of every 200 chest X-rays and most chest CT scans. 2  At least 60% of pulmonary nodules seen on chest X-rays turn out to be benign, and 99% of those on chest CT are benign. 3  Pulmonary nodules are much more commonly found than are lung cancers or benign lung tumors. A way to tell the difference between a benign and malignant lung nodule is to chart the rate of growth of the nodule. 2  Benign nodules will grow very slowly, if at all, while cancerous nodules on average can double in size every four months or less.
Answer: A solitary spot on a chest X-ray â generally referred to as a lung nodule â sometimes can be an early cancer, so it's important to talk to your doctor to determine the best course of action.Lung nodules are common and typically noncancerous (benign).ests may include the following: 1  CT scan of the chest if the nodule was first seen on a chest X-ray; 2  Positron emission tomography (PET) scan to see how active the nodule cells are â high cellular activity is an indicator of cancer or active inflammation; and/or. 3  Tissue sample (biopsy the nodule).
