Lung Cancer Progression And Staging – Manipal Hospitals



The most common form of lung cancer is non-small cell lung cancer. It is staged according to the size of the tumour and whether it has spread to the lymph nodes or other organs of the body. There are 4 stages of lung cancer. In the occult stage, cancer cells are accumulated in the fluids in the lungs and there is no tumour yet. In stage 0, cancer cells are found in the airway passages. Stage 1A and 1B are invasive cancer as tumour grows in the inner lining of airways and then spread into the bronchus. In stage 2A, it spreads to the lymph nodes on the same side of the chest. Stage 2B has two categories in which the cancer has invaded the diaphragm, chest walls and membranes around the heart and the tumour has grown in the bronchus and lymph nodes. In stage 3A, it spreads to lymph nodes and other structures nearby. In 3B, tumour may be of any size and spread to more lymph nodes on the same side and to nearby structures too. In stage 4, tumour has spread in other parts of the body.

This informative animated video explains in detail about the staging and progression of lung cancer. The staging of lung cancer refers to the extent of the disease. If one has the most common form of lung cancer or non-small cell lung cancer, it will be staged according to the size of the tumour and whether it has spread to lymph nodes or other nodes of the body. In occult or hidden stage, the cancer cells are found in the coughed up mucus or in other fluids, but no tumour can be seen in the lungs. Stage zero is not considered invasive because the cancer cells are found in the innermost lining of the air passages, but have not grown through it. Stage 1A is known as the invasive cancer, because the tumour has grown the inner lining of the airways into the deep lung tissue. Watch the video completely to know more on the staging of lung cancer.
