What is Lung Cancer?
Dr. Jain: A person is diagnosed with lung cancer when abnormal cells grow inside the lung(s). These cells attack the healthy tissue and form tumors. Lung cancer is defined in two categories, small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC). Small cell is more likely to spread and grow quicker compared to non-small cell. However, small cell is less common and is mostly seen in heavy smokers.
What are the Causes of Lung Cancer?
Dr. Jain: Most people who are diagnosed with lung cancer have a history of smoking. There are several factors besides smoking that can cause people to develop lung cancer. Those who are exposed to second hand smoke, asbestos, radon, or radiation are at a higher risk of being diagnosed with lung cancer.
What are the Symptoms of Lung Cancer?
Dr. Jain: Several symptoms can indicate lung cancer, but unfortunately, these symptoms rarely develop in the early stages. There are very few nerve endings in the lungs, allowing a tumor to grow without causing pain or discomfort. This is why lung cancer is often discovered at such a late stage. Symptoms of lung cancer may include:
- Persistent Cough
- Coughing up blood
- Shortness of breath or wheezing
- Chest pain
- Frequent lung infections such as bronchitis or pneumonia
Some symptoms of lung cancer are not related to the lungs or breathing because the cancer has spread to other parts of the body. These symptoms may include:
- Weight loss
- Loss of appetite
- Bone pain or fractures
- Blood clots
How Can I Prevent Lung Cancer?
Dr. Jain: In some instances, you can’t prevent lung cancer, but you can certainly decrease your risk. One of the best things you can do to lower your risk and for your overall health is to quit if you smoke and if you have never smoked, don’t start. Also discuss the dangers of smoking with your children. Other ways to lower your risk are:
- Test your home for radon
- Limit contact with secondhand smoke
- Know your family history
- Protect yourself from toxic chemicals at work
- Eat a healthy diet of fruits and vegetables
