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.
Simply, a benign lung nodule is not cancerous. A benign nodule or mass will not spread to other areas of the body. However, the presence of benign nodulesâespecially if they are largeâcan cause health problems. Even benign lung nodules may have to be surgically treated and removed. The most common types of benign lung nodules include: Granulomas: Inflamed or infected tissue that has congealed into a globular or ball-like shape. Hamartomas: Calcifications and scarring within the lung.
