A 6mm nodule in the lung is generally less malignant. If there are no other clinical symptoms, such as cough, hemoptysis, significant body wasting, fever and other symptoms, CT can be rechecked after 3 months. If there is no significant change, oral Chinese medicine soup treatment can be taken, which requires the combination of four diagnoses: look, smell, ask, and cut, forensic analysis, oral Chinese medicine regulation, and generally give symptomatic treatment with drugs to clear heat and detoxify, reduce swelling and disperse nodules. If the nodule is significantly enlarged, further examination of chest CT, lung tumor markers, bronchofibroscopy, etc. is recommended, and even pathology can be taken and pathological tests done. In case of malignant, it can be regulated by herbal soup, which can reduce the side effects of radiotherapy and improve the quality of life.
