Clinically, a burr with flat and smooth edges is benign, and a burr is a medical term that is usually found on chest radiographs or CT examinations as a mass with varying degrees of spine-like prominence. Most of the burrs found during the examination are benign, so there is no need to worry about regular follow-up. If the burrs at the edge of the mass are not only short but also very dense, the patient needs to be on high alert, and most of them are malignant masses. However, the burr in CT is not the only criterion, and further examination needs to be improved early and pathological examination is feasible. If the diagnosis is confirmed as malignant mass, surgery should be performed under the guidance of the doctor according to the actual physical condition of the patient, i.e. the size and stage of the tumor, and the timely treatment timing has a very important role in the patient’s prognosis. At the same time, it is necessary to pay attention to the maintenance in life, maintain regular life and rest, go out more often to exercise and improve body resistance, while the diet should be light, nutritious and high protein.
