A nodule is a small mass of tissue which forms in or on the body, usually in response to injuries. Nodules are typically hard and they can be easily felt. For the most part, the masses are benign, requiring no medical action, but sometimes they can interfere with the function of the body, or they may be malignant.
A tumor or nodule is a mass of cells that grows on the lungs. It can be benign (noncancerous) or malignant (cancerous). By detecting malignant tumors in an early stage with CT lung screening, the cancer cells can be treated at a time when the cancer still has promising survival rates and is localized to the lungs.
