What is lung cancer?

Lung cancer starts in the cells of your lungs. When normal cells in the lungs grow and divide uncontrollably, they form a mass or tumour that can invade surrounding tissues while spreading to other parts of your body. According to the cancer doctors in Kolkata, the most common types are non-small cell lung cancer and small cell lung cancer.

Some people with early-stage lung cancer may have no symptoms at all, while others may show symptoms that are similar to those of other respiratory illnesses. The most common symptoms of lung cancer include:

1. Persistent cough 2. Chest pain 3. Shortness of breath 4 . Wheezing 5. Hoarseness 6. Fatigue 7. Unexplained weight loss 8. Loss of appetite 9. Coughing up blood or rust-coloured sputum 10. Recurrent infections, such as bronchitis or pneumonia.

Here are some common causes of lung cancer listed by the best oncologist in Kolkata.

1. Smoking : The most common cause of lung cancer is smoking. Cigarette smoke contains harmful chemicals that might damage the cells in the lungs and lead to cancer. Also, breathing in other people’s smoke can also increase the risk of lung cancer. 2. Exposure to radon : Radon is a naturally-occurring gas that can seep into buildings and homes. Long-term exposure to high radon levels can enhance your risk of lung cancer. 3. Exposure to asbestos : Breathing in asbestos fibres can cause lung cancer and other respiratory diseases. 4. Exposure to carcinogens: Exposure to carcinogenic substances, such as arsenic, chromium, nickel, and diesel exhaust, can also increase the risk of lung cancer. 5. Genetic factors : Some people may have an inherited genetic predisposition to lung cancer, although this is relatively rare.

Chemotherapy : It uses drugs to kill cancer cells throughout the body. In this treatment, chemo might be used alone or in combination with other treatments. 3. Targeted therapy : Targeted therapy uses drugs that specifically target the genetic mutations or proteins that are driving the growth of cancer cells. 4. Immunotherapy : Immunotherapy uses drugs that help the immune system recognize and attack cancer cells. 5. Surgery : Surgery may be an option for early-stage lung cancer, where the tumour can be removed from the lung.
