- Lung Cancer Stage 0:
- The tumor is still in situ, and not yet become cancerous tumor.
- Lung Cancer Stage 1A:
- Tumor size is small, only 3 cm or less, it doesn't show any metastasis.
- Lung Cancer Stage 1B:
- The tumor is bigger (more than 3 cm), but it still not metastasis, yet.
- Lung Cancer Stage 2A:
- Tumor size is less than 3 cm, it is metastasis in ipsilateral peribronchial and/or ipsilateral hilar lymph nodes and intrapulmonary nodes, including involvement by direct extension.
- Tumor size is less than 3 cm, it is metastasis in ipsilateral peribronchial and/or ipsilateral hilar lymph nodes and intrapulmonary nodes, including involvement by direct extension.
- Lung Cancer Stage 2B:
- The tumor is bigger (more than 3 cm) and metastasis in ipsilateral peribronchial and/or ipsilateral hilar lymph nodes and intrapulmonary nodes, including involvement by direct extension.
or - Tumour of any size that directly invades any of the following: chest wall (including superior sulcus tumours), diaphragm, mediastinal pleura, parietal pericardium;or tumour in the main bronchus less than 2 cm distal to the carina but without involvement of the carina; or associated atelectasis or obstructive pneumonitis of the entire lung.
- Lung Cancer Stage 3A:
- The tumor size is 3 cm or more and metastasis in ipsilateral mediastinal and/or subcarinal lymph nodes.
or - Tumour of any size that directly invades any of the following: chest wall (including superior sulcus tumours), diaphragm, mediastinal pleura, parietal pericardium;or tumour in the main bronchus less than 2 cm distal to the carina but without involvement of the carina; or associated atelectasis or obstructive pneumonitis of the entire lung. It metastasis in ipsilateral peribronchial and/or ipsilateral hilar lymph nodes and intrapulmonary nodes, including involvement by direct extension or metastasis in ipsilateral mediastinal and/or subcarinal lymph nodes.
- Lung Cancer Stage 3B:
- Doesn't matter the size of the tumor, and it metastasis in contralateral mediastinal, contralateral hilar, ipsilateral or contralateral scalene, or supraclavicular lymph nodes.
or - Tumour of any size that invades any of the following: mediastinum, heart, great vessels, trachea, oesophagus, vertebral body, carina; separate tumour nodules in the same lobe; tumour with malignant pleural effusion. And it in any type of metastasis.
- Lung Cancer Stage 4:
- The tumor is already metastasis to other organ, and at any size.
