If the nodule is less than 10 mm in diameter, it can be temporarily observed without special treatment, and the CT will be repeated after 3 months. if the patient has a history of smoking, it is recommended to quit smoking as soon as possible, as smoking will stimulate the airway and increase the secretion in the airways, which will increase the probability of malignant lesions in the lung nodules. If there is no significant change in the nodules after CT review, you can take oral Chinese medicine tonics to regulate them, and generally give symptomatic treatment with drugs that clear heat and detoxify, reduce swelling and disperse nodules. If the nodules grow significantly, further examination of chest intensive CT, chest MRI, lung tumor markers, fiberoptic bronchoscopy, etc. is recommended. For patients clearly diagnosed with lung cancer, surgery is recommended as the main treatment for non-small cell carcinoma, supplemented by radiotherapy; for small cell carcinoma, radiotherapy is the main treatment, supplemented by surgery. It can be combined with the use of traditional Chinese medicine tonics, which can help to remove the evil and strengthen the capital, reduce the side effects of radiotherapy and chemotherapy, and improve the quality of life.
