Types of lung cancer:

1. Non-small cell lung cancer (NSCLC)
2. Small cell lung cancer (SCLC)
3. Adenocarcinoma
4. Squamous cell carcinoma
5. Large cell carcinoma
6. Carcinoid tumors
7. Mesothelioma

Non-Small Cell Lung Cancer (NSCLC)

- Adenocarcinoma: Arises from the cells that line the air sacs and produces mucus.
- Squamous cell carcinoma: Arises from the flat cells that line the airways.
- Large cell carcinoma: Arises from large, round, or oval cells.

Small Cell Lung Cancer (SCLC)

- Small cell lung carcinoma: Arises from primitive, rapidly dividing cells called neuroendocrine cells.

Other Types

- Adenosquamous carcinoma: A combination of adenocarcinoma and squamous cell carcinoma.
- Atypical carcinoid tumor: A rare type of lung cancer that grows slowly and has a low risk of spreading.
- Large cell neuroendocrine carcinoma: A rare type of lung cancer that behaves similarly to SCLC.
- Lymphoma: A type of cancer that starts in the lymph nodes or bone marrow and can spread to the lungs.
- Mesothelioma: A type of cancer that starts in the lining of the chest cavity or abdomen.
