When small lung nodules are found during a physical examination, first, the type of small lung nodules should be diagnosed, and second, targeted treatment should be performed to eliminate them. First, an intensive CT examination should be done to avoid small lung nodules caused by tumors. If they are caused by tumors, they need to be treated with surgery as soon as possible, and then further chemotherapy or radiotherapy measures should be chosen according to the pathological results. If the inflammatory nodules are caused by common lung infections, the treatment is relatively simple, often requiring hospitalization for intravenous drip treatment and anti-inflammatory treatment with appropriate and sensitive antibiotics based on sputum culture. Secondly, if tuberculosis nodules are caused by Mycobacterium tuberculosis, the treatment is also more complicated and you should go to a professional tuberculosis hospital for professional anti-TB treatment, and the course of the disease is longer, at least six months to a year, before you can fully recover.
