Multiple nodules in both lungs up to 7mm with unclear boundary may be benign nodules, such as inflammatory nodules, tuberculosis, etc., but malignant nodules such as lung cancer cannot be excluded.
1. Inflammatory nodules: mostly due to patients infected with bacteria and other pathogens, inflammatory reaction occurs in the lungs, gradually mechanized to form a mass of inflammatory pseudotumor, in the lung imaging examination found in the lungs of multiple nodules up to 7mm unclear border, the lesion is generally no obvious changes in the long term.
2. Tuberculosis: it is mostly related to the lowering of patients’ resistance and tuberculosis infection, which can lead to the emergence of multiple small nodules in both lungs with unclear boundary, often accompanied by coughing, coughing sputum, low-grade fever, night sweating, emaciation and other symptoms.
3. Lung cancer: Early stage of the tumor can also appear multiple nodules in both lungs, with unclear boundary and light density; as the tumor grows, the edge of the nodules will be lobed, and there will be pleural involvement, and the patient may have cough, hemoptysis, chest pain and other uncomfortable symptoms; in addition, patients with metastatic lung cancer will also have multiple nodules in lungs, with unclear boundary.
If patients have multiple nodules in both lungs with maximum 7mm and unclear boundary, it is recommended to consult doctor in time and carry out standardized treatment under doctor’s guidance.
