User: With reference to the text given, list some details about lung cancer
Assistant: 1. Lung cancer, sometimes referred to as lung carcinoma, is a cancerous tumour that starts in the lung.
2. Smoking cigarettes or inhaling toxic chemicals can aggravate genetic damage to the DNA of cells in the airways, which is what causes lung cancer.
3. In some cases, damaged airway cells acquire the capacity to proliferate unchecked, leading to the development of a tumour.
4. Lung tumours can spread throughout the lung if left untreated, impairing lung function.
5. Lung tumours eventually spread to other areas of the body and develop metastases, which lead to a variety of diseases.
6. The cells from which lung tumours develop are used to categorise them.
7. Adenocarcinomas, squamous-cell carcinomas, and large-cell carcinomas make up the majority of non-small-cell lung malignancies, which account for the remaining 15% of cases.
