There are many causes of multiple nodules in the lungs, and the treatment is different for different diseases, so you should choose the appropriate treatment for each disease. Clinically, multiple nodules in the lungs are commonly seen in lung infections, tuberculosis, and metastases in the lungs. If it is a lung infection, the nodules can usually disappear as long as anti-infection treatment is given; if it is tuberculosis, active anti-tuberculosis treatment can be given; if it is multiple metastases in the lung, it belongs to the advanced stage of cancer and active treatment measures should be taken, such as chemotherapy, radiotherapy, targeted therapy and Chinese medicine treatment to control the disease. It is difficult to achieve a cure, but can only try to relieve the patient’s symptoms, relieve pain and prolong life. Therefore, once multiple nodules are found in the lungs, it is important to pay attention to them and to improve the relevant tests to clarify the nature of the nodules and take targeted treatment. Multiple nodules in the lungs, if small, are usually benign. If you have a history of tumor and have multiple nodules in both lungs, you should pay attention to the possibility that the tumor has metastasized to the lungs.
