Staging of Lung Cancer
Lung Cancer is the most common cause of death worldwide accounting for 1.35 million
new cases per year and 1.18 million deaths for both incidence and mortality rate.
Lung Cancer is the uncontrolled growth of damaged lung tissues that is maybe due to metastasis infiltrating the lungs.
Symptoms of this disease may include dyspnea, hemoptysis, chronic coughing, wheezing, chest pain, cachexia or weight loss, dysphonia, clubbing of fingers due to hypoxia, and dysphagia.
There are four stages of lung cancer using the number staging system.
Stage 1 Non-Small Cell Lung Cancer is the type where the cancer growth is localized meaning it does not spread to lymph nodes yet. This stage may not manifest any obvious symptom yet not till an x-ray is done for another reason. Surgery can be treatment for this stage.
Stage 2 Non-Small Cell Lung Cancer is the stage where the tumor growth may have spread to local lymph nodes, but not any further. Persistent cough, of coughing out blood, shortness of breath, back pain, or repeated bronchitis are the common symptoms of this stage of cancer. Surgery can likewise be a treatment of choice for this. Radiation therapy can also be an option.
Stage 3 Non-Small Cell Lung Cancer is the stage considered to be locally advanced that means tumor growth has spread to lymph nodes on the same side of the body. The classical symptoms of stage 3 lung cancer are persistent cough, shortness of breath, and repeated infections such as pneumonia or bronchitis.
Stage 4 Non-Small Cell Lung Cancer is also called metastatic non-small cell lung cancer. This means that the tumor cells has metastasized to another region of the body. Symptoms include dyspnea, hemoptysis, chronic coughing, wheezing, chest pain, cachexia or weight loss, dysphonia, clubbing of fingers due to hypoxia, and dysphagia. Surgery and chemotherapy is the common treatment for this stage.
