What stage of lung cancer is the lung nodule 3cm-4cm?

Lung nodules are lung nodules. Lung nodules that are 3cm-4cm are not sure whether they are benign or malignant and whether they belong to lung cancer, let alone staging.

A pulmonary nodule is a small focal and round lesion in the lung. Imaging generally shows a shadow with increased density, which may be single or multiple, and is generally not accompanied by symptoms such as atelectasis, hilar enlargement, or pleural effusion. A solitary pulmonary nodule generally has no typical symptoms. It is usually a soft tissue shadow with clear boundaries and increased density, generally less than 3 cm in diameter, surrounded by air lung tissue. Nodules with a local lesion diameter greater than 3 cm are called lung masses. The possibility of lung cancer is relatively high, and further pathological examination is required to confirm. It is generally believed that more than 10 pulmonary nodules are diffuse nodules, which may be accompanied by symptoms. They can be caused by metastasis of malignant tumors in the chest or active infection, and the possibility of primary lung cancer is relatively small.

Lung nodules of 3cm-4cm cannot be determined to be benign or malignant. If the boundary is clear and there is no adhesion to the surrounding tissue, the possibility of malignancy is very small. In order to make a clear diagnosis, further examinations such as enhanced CT examination of the lungs or pathological examinations can be performed. Installment payment will only be involved when it is determined to be malignant, and the installment payment should be comprehensively judged based on whether it invades the surrounding tissues and whether there is remote metastasis and other symptoms.
