Causes of Lung Cancer
Several factors can increase the risk of developing lung cancer:Mayo Clinic+5Mayo Clinic+5Mayo Clinic+5
- Smoking: The leading cause of lung cancer, accounting for approximately 85% of cases. The risk increases with the number of cigarettes smoked and the duration of smoking.
- Secondhand Smoke: Exposure to tobacco smoke from others can also increase lung cancer risk.
- Radon Gas: A naturally occurring radioactive gas that can accumulate in homes and buildings, leading to increased risk.Wikipédia
- Asbestos and Other Carcinogens: Exposure to asbestos fibers and other harmful substances in the workplace can elevate the risk.
- Family History: A family history of lung cancer may increase an individual’s risk, suggesting a genetic predisposition.
Prevention
While not all cases of lung cancer are preventable, certain measures can significantly reduce risk:
- Avoid Smoking: The most effective way to prevent lung cancer is to never start smoking or to quit if you currently smoke.
- Test for Radon: Regularly test your home for radon levels and take necessary actions to reduce exposure.
- Protect Against Carcinogens: Follow safety guidelines to avoid exposure to known carcinogens in the workplace.
- Maintain a Healthy Diet: A diet rich in fruits and vegetables may help reduce the risk of lung cancer.
