Lung cancer is a deadly disease that affects millions of people all over the world every year. Typically, this disease is associated with smokers or people who have a history of smoking in their family.

However, recent studies show that even non-smokers are at higher risk of developing lung cancer than previously believed. In fact, non-smokers are 2.5 times more likely to develop lung cancer than those who do not smoke at all. This is a concerning fact that everyone should be aware of.

What Is Lung Cancer?

Lung cancer is a disease that occurs when abnormal cells grow out of control in the lungs. These cells can form tumors that can spread to other parts of the body, making treatment more difficult.

There are two main types of lung cancer: non-small cell and small cell. Non-small cell is the most common form of lung cancer, accounting for about 85% of all cases. Small cell lung cancer is less common but more aggressive.

Why Are Non-Smokers At Higher Risk?

There are several factors that can put non-smokers at higher risk for lung cancer:.

Exposure to radon: Radon is a radioactive gas that is found in soil and rocks. When it seeps into buildings, it can accumulate and cause lung cancer.
Air pollution: Exposure to pollutants in the air can cause lung cancer, even if the person has never smoked.
Second-hand smoke: Breathing in second-hand smoke can be just as dangerous as smoking, putting non-smokers at risk for many health problems including lung cancer.
Genetic factors: Some people may be more genetically susceptible to lung cancer than others, even if they have never smoked or been exposed to other risk factors.

Symptoms of Lung Cancer

Some symptoms of lung cancer include:.

A persistent cough that gets worse over time
Chest pain that does not go away
Coughing up blood
Shortness of breath
Wheezing
Fatigue
Unexplained weight loss
Loss of appetite

Diagnosis and Treatment

If you are experiencing any of these symptoms, see a doctor right away. The doctor will perform tests to determine if you have lung cancer. These tests may include:.

X-rays or CT scans to look for abnormalities in the lungs
A biopsy to remove a small sample of lung tissue for testing
Blood tests to check for cancer markers

If you are diagnosed with lung cancer, your treatment will depend on the type and stage of your cancer. The most common treatments include:.

Surgery to remove the cancerous tissue
Radiation therapy to kill cancer cells
Chemotherapy to destroy cancer cells

Prevention

While there is no guaranteed way to prevent lung cancer, there are some steps you can take to reduce your risk:.

Avoid smoking or exposure to second-hand smoke
Test your home for radon and take steps to reduce the amount of radon present
Avoid exposure to air pollution whenever possible
Eat a healthy diet that is rich in fruits and vegetables
Exercise regularly
Get regular check-ups with your doctor

Conclusion

Even if you have never smoked, you are still at risk for lung cancer. By knowing the risk factors and the symptoms of this deadly disease, you can take steps to reduce your risk and get prompt treatment if you do develop lung cancer.
