What stage does a 2 cm lung cancer belong to

It is impossible to determine exactly what stage a 2 cm lung cancer tumor belongs to, mainly because the staging of lung cancer, in addition to the size of the tumor, also requires consideration of lymph node metastasis and distant metastasis.

Lung cancer mainly refers to malignant tumors originating from the bronchial mucosa or glands, and can be staged using the TNM system. T is mainly used to describe the size of the tumor, with results ranging from T0 to T4. T0 means no lesions were found, T3 represents a cancer diameter between 5 cm and 7 cm, and N describes whether the cancer cells have spread to the lymph nodes. N1 means that the cancer cells have spread to the lymph nodes connecting the lungs to the airways, and N2 indicates that they have spread to the mediastinum and lymph nodes near the trachea. M represents whether the cancer cells have spread and where they have spread. M0 means that the cancer cells have not spread, and M1 means that they have spread to other areas.

The stage of lung cancer of 2 cm cannot be determined based on the size of the lesion alone. You need to seek medical attention promptly and have the doctor determine the stage through imaging examinations. Treatment will be provided based on the stage to prevent the disease from becoming serious.
