Lung Nodules

Lung nodules are abnormal growth formed on the lungs that can be benign or malignant. It is usually shown on the X-rays or CT scans. Benign nodules are noncancerous and do not spread to other parts of the body. Malignant nodules are cancerous and can spread quickly. Noncancerous lung nodules occur due to infection, noninfectious inflammation, and noncancerous tumors. Lung nodules do not cause any symptoms if it is benign. But, it can cause breathlessness, chest pain, back pain, and weight loss when caused due to lung cancer. If it is a noncancerous one, its treatment depends on the cause. Cancerous lung nodules are removed using thoracotomy, chemotherapy, and radiation therapy.
