Subpleural nodule in the right lung tip may be tuberculosis, pleural tuberculosis; or lung cyst, lung adenocarcinoma and other diseases, which can be treated with general treatment, drug treatment, conservative treatment or surgery, radiotherapy and so on according to the cause. 1. Tuberculosis, pleural tuberculosis: mainly due to the infection of Mycobacterium tuberculosis, after diagnosis, oral anti-tuberculosis drugs should be taken as soon as possible, such as isoniazid and rifampicin, etc., and after eliminating the Mycobacterium tuberculosis, the nodules will naturally shrink and disappear. 2. Lung cyst: it is a kind of cystic lesion in the lungs. Smaller lung cysts usually do not need special treatment, while larger lung cysts have the risk of rupture and bleeding on their own, so resection should be performed as soon as possible. 3. Lung adenocarcinoma: it will form cancerous nodules, and in the early stage, radical surgery will be recommended to remove the tumor, including lobectomy, segmental resection, wedge resection, etc., which should be decided according to the spreading of cancer cells. Ordinary patients are prone to metastatic spread after surgery, and radiotherapy should be carried out as soon as possible after surgery to inhibit the cancer cells, and commonly used chemotherapeutic drugs include capecitabine, pemetrexed, and so on. Regarding the subpleural nodule in the right lung tip, it is recommended to do pathological biopsy for diagnosis and analysis as soon as possible, and if medication is needed, it should be done under the guidance of doctor.
