Lung cancers can arise in any part of the lung, but 90%-95% of cancers of the lung are thought to arise from the epithelial cells, the cells lining the larger and smaller airways (bronchi and bronchioles); for this reason, lung cancers are sometimes called bronchogenic cancers or bronchogenic carcinomas.
Lung cancers generally are classified into two major types:
Non-small cell lung cancer is the most common type of lung cancer, accounting for about 85 to 90 percent of all diagnoses and Small cell lung cancer, also known as oat-cell cancer, accounts for less than 20 percent of lung cancer cases. In most cases, this cancer type is caused by tobacco smoking. It tends to spread quickly to other parts of the body.
Smoking is the leading cause of lung cancer. More than 80 percent of lung cancer deaths can be attributed to smoking. Lung cancer is the most common type of cancer among men and women in India. Our Thoracic Cancer Management Team (CMT) is focused on battling this grave danger; our blueprint to combat lung cancer comprises a 360 degree, multi-disciplinary approach that combines the best of technology, the most skilled personnel and cutting-edge treatment modalities.
Adenocarcinoma- is the most common subtype of lung cancer which usually arises from the peripheries of the lung. In a significant proportion of these patients have driver mutations such as EGFR, ALK, Ros1, RET, MET, Her2 Neu, etc. which can be potentially treated with targeted therapies. Squamous cell carcinoma- Second most common subtype and arises in the central portions of the lung, it is often associated with a history of smoking and is associated with necrotic mediastinal nodes.
Small Cell carcinoma - Is a rapidly growing subtype of cancer arising from the central portions of the lungs and is often associated with advanced disease and high propensity for brain metastases.
Other Uncommon subtypes are as follows:
Lung cancer does not always have symptoms. If symptoms are present, they may include:
