What are the stages of lung cancer?
Lung cancer can be divided into two major types: Small cell lung cancer and non-small cell lung cancer.
The stages of small cell lung cancer include:
- Limited stage: Just one lung and possibly nearby lymph nodes, not spreading to both lungs yet.
- Extensive stage: the tumor has spread to the fluid around your lungs or other organs like your brain.
The stages of non-small cell lung cancer include:
Occult stage: It is also called hidden cancer. The tumor can’t be seen on imaging scans or a biopsy even though the cancer cells can be picked up in the mucus.
- Stage 0: The tumor is very small, not spreading into deeper lung tissues or outside your lungs.
- Stage I: The cancer can be found in lung tissues, but not in lymph nodes.
- Stage II: The cancer has spread to lymph nodes near lungs.
- Stage III: The cancer has spread further into your lymph nodes and the middle of your chest.
- Stage IV: The cancer has spread widely around your body, like the brain, liver or bones.
