Most solid lung nodules are benign lesions, and data suggest that less than 10% of solid lung nodules are considered to be cancerous. Most solid lung nodules are usually benign and may be associated with inflammatory infections, tuberculosis and other factors. However, current data suggests that less than 10% of solid lung nodules should be considered cancerous, such as lung adenocarcinoma and squamous cell carcinoma. If solid lung nodules are cancerous, patients are also prone to symptoms such as fatigue, weight loss, night sweats, and anemia. If you want to know whether it is cancer or not, you can undergo further tests such as lung biopsy through the chest wall and tumor marker tests. It is recommended that patients with solid lung nodules should go to regular hospitals for consultation, so as to choose appropriate treatment measures after clarifying the benign or malignant nature of the lung nodules, and should also pay attention to regular medical checkups.
