Can scattered nodules in both lungs disappear on their own?

In general, scattered nodules in both lungs refer to the presence of multiple separate nodular lesions found in both lungs during chest X-ray or CT examination. Whether these scattered nodules in both lungs can disappear on their own depends on their nature. Benign nodules may resolve spontaneously, whereas malignant nodules will not disappear without treatment. If there is any discomfort, timely medical consultation is recommended. Detailed explanations are as follows:

B benign nodules are usually caused by pulmonary inflammation, old injuries, or other nonmalignant factors. After their formation, these nodules may be gradually absorbed or reduced in size, and even completely resolved, as the inflammation subsides, tissue repairs itself, or immune function improves. Additionally, some benign nodules may be temporary, such as those caused by transient pulmonary inflammation or congestion, which may naturally disappear after the inflammation resolves.

Malignant nodules represent lung cancer or other malignant tumors present in the lung, with growth and spread caused by continuous division and proliferation of cancer cells. These cancer cells have uncontrolled growth potential and can destroy surrounding normal tissues. Therefore, once formed, malignant nodules typically do not resolve spontaneously but tend to continue growing and may metastasize to other areas.

In daily life, maintaining healthy lifestyle habits, such as quitting smoking, limiting alcohol consumption, maintaining a balanced diet, and engaging in moderate physical activity, can help maintain lung health.
