Understanding Lung Cancer Symptoms and Causes

Understanding Lung Cancer Symptoms and Causes | Dr. Ashish Pokharkar


Lung cancer is a formidable health challenge that affects millions of people worldwide. It is a condition characterized by the uncontrolled growth of abnormal cells in the lung tissues. Early detection and understanding of the symptoms and causes of lung cancer are crucial for effective treatment and improved outcomes. In this blog, we’ll delve into the key symptoms and causes of lung cancer, guided by the expertise of Dr. Ashish Pokharkar, a renowned cancer surgeon.

Lung Cancer Symptoms

Recognizing the symptoms of lung cancer is vital as they often appear in the later stages of the disease. Some common symptoms include:

  • Persistent Cough: A chronic cough that doesn’t subside after weeks can be an early indication of lung cancer. This cough may produce blood-tinged or rust-colored mucus.
  • Shortness of Breath: If you find yourself becoming breathless with minimal exertion or even at rest, it could be a sign of lung cancer. This occurs due to the tumor obstructing the air passages or fluid accumulation in the lungs.
  • Chest Pain: A persistent, dull, or sharp pain in the chest, shoulders, or back can be an indication that the tumor has spread to the surrounding tissues or nerves.
  • Unexplained Weight Loss: Sudden and unexplained weight loss can occur due to the body’s increased energy expenditure as it fights the cancerous cells.
  • Hoarseness or Wheezing: Changes in your voice, such as hoarseness, and wheezing might occur if the tumor affects the nerves or airways.
  • Fatigue: Feeling excessively tired, even after adequate rest, can be attributed to the body’s immune response against the cancerous cells.

Lung Cancer Causes

Understanding the causes of lung cancer is essential for adopting preventive measures and making informed lifestyle choices. The primary causes include:

  • Smoking: Cigarette smoking is the leading cause of lung cancer. The harmful chemicals in tobacco smoke can damage the cells lining the lungs and trigger the development of cancerous growths.
  • Secondhand Smoke: Even if you’re not a smoker, exposure to secondhand smoke can increase your risk of developing lung cancer. The toxic compounds present in cigarette smoke affect non-smokers as well.
  • Radon Gas: Radon, a colorless and odorless radioactive gas, is a natural byproduct of uranium decay in soil. Prolonged exposure to high levels of radon can significantly raise the risk of lung cancer.
  • Asbestos Exposure: Occupational exposure to asbestos, commonly found in construction and insulation materials, can lead to the development of lung cancer, particularly if coupled with smoking.
  • Air Pollution: Long-term exposure to polluted air containing carcinogens can increase the risk of lung cancer.
  • Family History: Genetics plays a role in the development of lung cancer. If you have a family history of the disease, your risk might be elevated.


Dr. Ashish Pokharkar’s Insights In the fight against lung cancer, early detection and understanding the underlying causes are of paramount importance. Dr. Ashish Pokharkar, a distinguished cancer surgeon, emphasizes the significance of a comprehensive approach to tackling this disease. He advocates for regular screenings, particularly for individuals with a high risk due to smoking or other factors. Dr.  Ashish Pokharkar also stresses the importance of raising awareness about the harmful effects of tobacco and the need for strict regulations on tobacco products to reduce the incidence of lung cancer.

To conclude, by recognizing the symptoms and understanding the causes of lung cancer, we can take proactive steps to safeguard our health. Regular health check-ups, avoiding tobacco products, minimizing exposure to environmental pollutants, and staying informed about the latest advancements in lung cancer research can collectively contribute to a healthier future. Let’s work together to spread awareness and support ongoing efforts to combat lung cancer under the guidance of experts like Dr. Ashish Pokharkar.
