Lung Cancer
What is Lung Cancer
Lung cancer is a type of cancer that begins in the cells of the lungs. It is the leading cause of cancer-related death worldwide, and is the most common cancer among men in India.
Signs and Symptoms of Lung Cancer
The most common symptom of lung cancer is a persistent cough, but other symptoms may include:
- Chest pain
- Coughing up blood
- Shortness of breath
- Wheezing
- Hoarseness
- Weight loss and Fatigue
If you experience any of these symptoms, it’s important to speak with a medical professional as soon as possible.
Cause
The main cause of lung cancer is smoking, but other factors, such as exposure to secondhand smoke, air pollution, and certain occupations, may also increase the risk of developing the disease.
Stages of Lung Cancer
There are four stages of lung cancer:
- Stage I: Cancer is present, but is small and has not spread beyond the lungs
- Stage II: Cancer is larger and may have spread to the lymph nodes
- Stage III: Cancer is larger and has spread to the lymph nodes and surrounding tissues
- Stage IV: Cancer has spread to other parts of the body

Prevention, Screening, and Diagnosis of Lung Cancer
The best way to prevent lung cancer is to avoid smoking and exposure to secondhand smoke. If you are a smoker, quitting is the most effective way to lower your risk of lung cancer.
Screening tests, such as low-dose CT scans, may be recommended for certain individuals at high risk of lung cancer. If lung cancer is suspected, your doctor may order further tests, such as a biopsy, to confirm the diagnosis.
Treatment Options for Lung Cancer
The treatment plan for lung cancer will depend on the stage of the cancer, as well as the patient’s overall health and personal preferences. Treatment options may include:
Surgery: This may include a lobectomy, which removes a portion of the lung, or a pneumonectomy, which removes the entire lung.
Chemotherapy: This treatment uses drugs to kill cancer cells.
Radiation therapy: This treatment uses high-energy beams, such as X-rays, to kill cancer cells.
Immunotherapy: This treatment helps the immune system fight cancer cells.
Targeted therapy: This treatment targets specific proteins or genes that play a role in the growth and spread of cancer cells.
If you have been diagnosed with lung cancer, it’s important to work with your medical team to determine the best treatment plan for you. With the right treatment and support, it is possible to manage lung cancer and improve your quality of life.
