Lung cancer is said to be the most widespread type of cancer in the world. As per the WHO, lung cancer alone was responsible for 1.7 million deaths in 2015. But did you know lung cancer is not just of one type? Most of the time, the type of treatment is decided based on the lung cancer type one is suffering from. The classification of lung cancer is made on the basis of various factors.

Here are the types of lung cancer you need to be aware of:

1. Non-Small Cell Lung Cancer (NSCLC) – It is one of the most prevalent types of lung cancer. It constitutes almost 80% to 85 % of the cases but spreads slowly to the other parts of the body. It further has the following subtypes based on the location of the origin of the cancer cells-

  • Adenocarcinomas – this type of cancer develops in the lining of the lungs (therefore having a better prognosis rate in comparison to the other types of lung cancer) and is said to occur more commonly among women.
  • Squamous cell carcinomas – this type mostly originates in the central part of the bronchi.

2. Small Cell Lung Cancer (SCLC) ­– Another of the common types of lung cancer, in SCLC the cancer cells are comparatively smaller than the other cancer cells. Though the cells might be small in size, this cancer spreads very quickly, thus making it the most dangerous type of lung cancer. It is very aggressive, has a strong link to smoking, and requires immediate medical attention. Although, only 15%-20% of lung cancer cases are of this variant.

3. Lung Carcinoid Tumors – This type of lung cancer starts in the Neuroendocrine cells – cells responsible for the lungs’ growth and blood and airflow. It is further classified into the following

  • Typical carcinoids – Even non-smokers are at risk of developing this type of lung cancer. It progresses very slowly and is mostly confined within the lungs itself.
  • Atypical carcinoids ­– Between the two subtypes, this one is rarer but spreads more speedily. It is said to be more prominent among smokers.

4. Mesothelioma – this mainly results from too much asbestos exposure. The differentiating aspect of this type of lung cancer is that its origin point is not only within the lungs but also in the lining of the neighboring areas like the heart and the abdomen.
