Trying to take deep breaths all the time does not necessarily mean lung cancer, but also other obstructive lung diseases, such as chronic obstructive pulmonary disease and emphysema are possible. Lung cancer also has this symptom if it is accompanied by dyspnea, breathing with chest tightness and difficulty in breathing. Generally, if such discomfort occurs, further CT examination of the chest is needed, which can clarify whether there is any lung occupancy, and further percutaneous lung aspiration biopsy can confirm whether it is lung cancer. If it is lung cancer, on one hand, symptomatic treatment is needed to see if surgery is possible. For lung cancer that can be treated surgically, surgery is the main treatment, and postoperative treatment is combined with adjuvant radiotherapy and chemotherapy. If there is a mutation in the genetic test, the treatment with targeted drugs may have better effect.
