A 0.9cm solid nodule on the lung requires CT, PET-CT or puncture biopsy to clarify the type of pathology and determine the benign or malignant nodule.
Solid lung nodules can be classified as benign or malignant nodules. Benign nodules mainly include benign granulomas, scarring and intrapulmonary lymph nodes, while malignant nodules may be malignant tumors, metastases, and so on.
If there is a single 0.9 cm solid lung nodule confirmed by imaging, CT, PET-CT or puncture biopsy is needed within 3 months to clarify the pathologic type of the nodule and provide targeted treatment. However, in the case of multiple >0.8 cm solid lung nodules, repeat CT is recommended at 3-6 months and again at 18-24 months.
For the appearance of solid lung nodules, it is recommended to seek medical treatment as soon as possible to clarify the diagnosis and standardize the diagnosis and treatment.
