Lung cancer, also described as lung carcinoma, is a type of malignant lung tumor caused by unregulated cell growth in lung tissues. This growth has the potential to spread beyond the lung through metastasis into nearby tissue or other parts of the body. The majority of cancers that begin within the lung, known as primary lung cancers or carcinomas.

- asbestos
- beryllium
- cadmium
- Fumes from coal and coke
- silica
- nickel
Find out greater approximately asbestosis and silicosis.
Research also shows that being uncovered to diesel fumes over a few years will increase your threat of growing lung most cancers. One study has proven your threat of growing lung most cancers will increase with the aid of around 33% in case you stay in an area with high stages of nitrogen oxide gases (typically produced by motors and different vehicles).
