Cysts on the lungs in the elderly are usually not important. A cyst on the lung, also called a pulmonary cyst, is a benign lesion, and this benign lesion does not have a great impact on the human body, especially if the cyst is relatively small, and does not produce corresponding clinical symptoms, neither causing coughing, coughing, nor fever symptoms. If there is a combination of infection, fever, cough and sputum can appear before treatment is needed, for example, amoxicillin, cefuroxime, cefaclor and other drugs can be used for anti-infection treatment. In the vast majority of cases, a complete cure can be achieved, which means that the infection can be effectively controlled and does not produce sequelae. Therefore, the presence of cysts on the lungs of the elderly is not very relevant in most cases.
