Can lung carcinoma in situ disappear on its own?

In general, lung carcinoma in situ does not disappear on its own. Lung carcinoma in situ is an early stage of lung cancer and will not resolve spontaneously; timely intervention and treatment are required. The specific analysis is as follows:

Lung carcinoma in situ refers to an early form of lung cancer characterized by the proliferation of epithelial cells that already exhibit malignant features morphologically, while the basement membrane remains intact. Typically, lung carcinoma in situ rarely invades surrounding tissues or undergoes early metastasis, and most cases remain stable. Early surgical resection can achieve a cure with a low recurrence rate. However, if left untreated, it will not disappear spontaneously.

Even after successful treatment of lung carcinoma in situ, patients should continue monitoring their health. The presence of carcinoma in situ often indicates impaired immune surveillance against tumors, increasing the risk of developing new tumors in other tissues or organs. Patients should undergo annual physical examinations and eliminate unhealthy habits such as smoking and excessive alcohol consumption. Regarding diet, patients should avoid heavy consumption of meat and fatty foods, and instead consume foods rich in protein, fiber, and vitamins, ensuring a balanced and nutritious diet.

If patients experience any discomfort or symptoms, they should seek medical attention at a hospital promptly to avoid delays in diagnosis and treatment.
