Is lung tumor larger than 3cm stage 1?

Lung cancer

can be classified as benign or malignant. For benign lung tumors, there is no staging, so no matter how large or small they are, they do not belong to stage I. For malignant lung tumors, such as lung cancer, staging is mainly based on TNM staging system. Although tumor size is also one of the factors affecting staging, it is also necessary to make comprehensive judgment in combination with lymph node metastasis and distant metastasis to determine staging. For example, if the tumor is 3 cm 3 cm, it is accompanied by ipsilateral bronchial or hilar lymph node metastasis, usually belonging to stage II; if the tumor has distant metastasis, no matter how big the primary lesion is, it usually belongs to stage IV.
