Lung cancer is one of the most deadly and fatal diseases of modern age that is growing rapidly in every parts of the world. Though advanced medical science is vigorously trying to find remedies to this disease, it is yet to get a concrete solution that can help patients recover from lung cancer completely. However, doctors have categorized lung cancer staging as four types in accordance to their treatment process, starting from diagnosis to clinical processing.

The disease of lung cancer most commonly starts from a small portion and gets spread at various parts of the body, thus affecting the functioning of the organs which ultimately leads to death if not treated at initial stage. Some of the common forms of diagnosis that are used to detect lung cancer staging are bronchoscopy, chest x-ray, CT Scan, MRI, PET scan, sputum cytology, needle biopsy, thoracentesis and many more.

Below given are the four lung cancer staging that you should be informed about to stay alert and aware:

• Stage 1: This is accepted as the first or initial stage of lung cancer where the cancer is localized in a small part of the body. This is the best stage to start treatment as the disease is yet to grow and spread to other parts, thus allowing doctors with the scope of detection and operation in accordance to need. In this lung cancer staging, the tumor remains small which is not more than 5 centimeter in size.
• Stage 2: In this stage, the tumor of lung cancer starts growing towards the chest, lungs lining and even nearly lymph nodes that gradually increase the danger of the disease.
• Stage 3: This is the third stage of lung cancer which is considered as one of the most critical lung cancer staging. In this stage, the tumor grows very large and spreads over large area, thus affecting other organs.
• Stage 4: This is the last stage of lung cancer in which the tumor gets spread beyond treatment, thus affecting almost distant parts of the body.

It’s observed that doctors get a better chance of treatment if the patient is diagnosed at the initial stages such as stage 1 or stage 2. However, once a patient moves towards the higher lung cancer stages, it becomes difficult as the tumor affects different parts of the body at rapid speed. Some of the popular treatment processes of lung cancer include surgical removal, chemotherapy, radiation therapy etc.
