Lung cancer is one of the deadliest types of cancer, and it has always been thought to be caused by smoking. But recent studies have shown that about 10-15% of lung cancer patients have never smoked or been exposed to secondhand smoke.

Here are some other risk factors you need to be aware of:.

Air Pollution

Exposure to air pollution, such as smog, can increase your risk of getting lung cancer. Pollutants like radon, asbestos, and diesel exhaust can have a harmful effect on your lungs.

Family History

Genetics can play a significant role in your risk of developing lung cancer. If you have a first-degree relative such as a parent, sibling, or child who has been diagnosed with lung cancer, your chances of developing it increase by 25%.

Radiation Therapy

If you have undergone radiation therapy for cancer, especially in the chest area, you are at a higher risk of getting lung cancer. The risk increases, even more, when radiation therapy is combined with smoking.

Exposure to Chemicals

People who work in certain industries, such as mining, paint manufacturing, or chemical manufacturing, are at a higher risk of developing lung cancer due to exposure to certain chemicals.

The chemicals that put you at risk include arsenic, chromium, and nickel.

Lung Diseases

If you have been diagnosed with a lung disease, you have a higher risk of developing lung cancer. Chronic obstructive pulmonary disease (COPD) and tuberculosis are linked to an increased risk of getting lung cancer.

Diet and Exercise

Your lifestyle choices can also increase your risk of developing lung cancer. If you have a poor diet and do not exercise, your immune system may be weaker, making it harder for your body to fight off cancerous cells.

Hormonal Factors

Women who have been through menopause are at a higher risk of developing lung cancer than women who have not gone through it yet.

Additionally, some studies have shown that women who use hormone replacement therapy are at a higher risk of getting lung cancer.

Age

The older you get, the higher your risk of getting lung cancer. Most cases of lung cancer are diagnosed in people over 65 years old.

Immune System

People who have a weakened immune system, such as those with HIV or who have had an organ transplant, are at a higher risk of getting lung cancer.

Conclusion

While smoking remains the leading cause of lung cancer, non-smokers are still at risk for this deadly disease. By knowing the risk factors, you can take precautions to minimize your chances of getting lung cancer.

Maintaining a healthy diet and lifestyle, getting regular checkups, and avoiding exposure to harmful chemicals and air pollution can help reduce your risk of developing lung cancer.
