Lung cancer is a common kind of cancer as well as a deadly killer. Many studies point out that smoking is the main culprit leading to cancer, but there are other factors that cannot be ignored! Plus, if lung cancer is detected at its early stage, the chances of recovery can be much higher. So, make sure to get regular health check-ups for prompt treatment before cancer reaches its intermediate or late stage.

Quit smoking

Smoking is one of the main causes of lung cancer. Tar in cigarettes can damage the cells in the lungs and trachea, causing the cilia in the lungs to lose their ability to clear out dirt and mucus, hence a higher risk of lung cancer. If you’re a smoker, quit smoking as soon as possible.

Avoid inhaling second-hand smoke

Non-smokers should stay away from second-hand smoke as far as possible as people inhaling second-hand smoke are twice more likely to get lung cancer than those who don’t. If you have family members or colleagues smoking next to you, walk away from them or tell them to smoke in outdoor areas.

Stay away from air-polluted places

According to the World Health Organization, air pollution is another major cause of lung cancer after smoking. The airborne particulate matter can trigger inflammation in the lungs, hence a greater risk of lung cancer. You should avoid staying in air-polluted places for a long time, such as highly polluted cities and industrial areas.

Avoid contacting harmful substances

Exposure to harmful substances like asbestos, carbon monoxide, silicon, zinc and radioactive materials can also increase the risk of lung cancer. When these substances are disturbed by chemical reactions, they will release tiny fibres into the air which can be absorbed by humans, leading to a greater chance of lung cancer. If you are exposed to these substances in your working environment, wear protective gear as much as possible.

Eat more fruits and vegetables

Fruits and vegetables are rich in vitamins and antioxidants that can help prevent lung cancer. You are advised to eat five servings of fruits and vegetables every day such as green and orange vegetables to protect your health.

Green vegetables: For example, spinach, loofah and Chinese kale are rich in vitamins C and K and folic acid that help keep your lungs healthy.

Orange vegetables: For example, carrots, pumpkin and bell pepper contain rich antioxidants like β-carotene that help reduce the risk of lung cancer.

Receive regular examinations

Lung cancer can sneak up on you with unobvious or confusing symptoms similar to that of respiratory diseases at the early stage. The most effective way to prevent and detect lung cancer is by receiving regular health check-ups at least once a year. You should follow your doctor's instructions to undergo lung X-rays, CT scans, or other tests to fully understand the health of your lungs and detect and treat any underlying issues as soon as possible.
