Here’s everything you need to know about Lung Cancer

Lung cancer is a deadly disease. It spreads to lymph nodes or other organs in the body. It is said that people who smoke are more at risk of developing this type of cancer as when one smokes, it gradually damages cells in the lung lining. 

Smoking can lead to a change in lung tissue. People who are exposed to secondhand smoke for a prolonged amount of time are also at risk of developing this disease. Lung cancer can also happen to people who have never smoked. Read on to know the diagnosis, types and symptoms of lung cancer.




X-ray is the very first test of lung cancer which is done when doctors suspect something. This is followed by tests like CT, PET and MRI.


To know the stage of cancer, doctors diagnose it medically by finding out how big is the tumour (T), where it is, how near it is to the lymph nodes (N) and how far (M) has cancer spread from its original spot. 




Stage 3 of lung cancer is divided into three groups, namely Stage IIIA, Stage IIIB and Stage IIIC. 


Stage A is when the tumors (or tumor) are present in only the lung. 


Stage B is when the tumours are present in the same lung but have spread to lymph nodes above the collarbone and might have also spread to the other side of the chest, but haven't yet reached other organs. 


Stage C is where the lung cancer has spread to lymph nodes above the collarbone and also to the opposite side of the chest. It could have reached the chest wall, breastbone or other nearby tissues also at this stage.





Some common symptoms of lung cancer may include:


Chest pain.

Unexplained weight loss.

A persistent cough.

Coughing up blood.


Pain in the bones.
