Is a small nodule in the lung something to be concerned about?

Pulmonary small nodules refer to lung nodules with a diameter less than 3 centimeters, commonly found on CT scans of the lungs, and are usually benign. However, if a nodule exceeds 3 centimeters in diameter or shows clear signs of growth, close monitoring and further evaluation are required. If the nodule is diagnosed as malignant, prompt treatment is necessary. Even if the nodule is determined to be benign but demonstrates significant growth, it still requires careful follow-up and additional testing to rule out the possibility of malignancy. It is recommended to seek medical attention promptly.
