Lung Nodule

Lung nodules are small masses of tissue in the lung, and they appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. About 40% of these growths are benign, the cancerous lung nodules are often found in older people and smokers.

The common lung nodules are about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. A lung nodule which is 30 millimeters or larger is more likely to be cancerous.

The imaging test can help to check the disease. And if the nodule on earlier images hasn’t changed in size, shape or appearance in two years, it’s probably noncancerous.

A non-cancerous lung nodule can be caused by a variety of conditions, including bacterial infections like tuberculosis and histoplasmosis, inflammatory diseases like rheumatoid arthritis, birth defects, parasitic infections, and tissue abnormalities, like lung cysts and hamartomas. While cancerous lung nodule can be caused by lung cancer, breast cancer, and colon cancer.

A benign lung nodule generally only needs treatment if it causes symptoms severe enough to impact breathing. While a cancerous lung nodule needs surgery to remove the masses of tissue.
