Lung cancer is the growth of abnormal cells or malignant tumors that attack the lungs.

Most lung cancers are caused by exposure to cigarette smoke. However, they can also be people who do not smoke affected by this health problem.

To understand which types of cancer are more common, identify the characteristic causes of lung cancer.

What causes lung cancer?

Lung cancer can occur due to changes or mutations of cells in the lungs. The cause of lung cancer can be influenced by several factors. Here are some of them:


Launch of the American Lung Association, exposure to secondhand smoke is the leading cause of lung cancer. About 90 percent of lung cancer cases are related to smoking.

Cigarette smoke contains various chemicals that can trigger lung cancer not only in active smokers, but also passive smokers.

In fact, people who experience smoking stagnation are still at risk of lung cancer. However, the risk is lower than active smokers.


Karui Media WebMD reports, vaping or electric cigarettes can also cause lung cancer like cigarettes.

Because vaping contains nicotine, flavor chemicals and several other toxic substances that are inhaled in the lungs.

radon gas

Radon gas is a chemical that causes lung cancer that is difficult to see, smell or taste.

This gas is radioactive, odorless and, naturally, can be found in some areas.

This gas can emerge through the ground or small spaces, such as floors or rocks. To detect this gas, it is recommended to carry out regular radon tests at home.


Asbestos is a substance that can cause lung cancer when inhaled.

Asbestos is commonly used as a construction material, which is found in cars and some other products.

When inhaled, asbestos breaks down into tiny fibers that can get stuck, accumulate and damage the lungs.

Air pollution

Air pollution contains acids, chemicals and harmful metals. The particle size of air pollution is smaller than sand.

When they are inhaled, air pollution particles can lodge in the lungs and activate cancer.

Hazardous chemicals

Hazardous chemicals such as uranium, arsenic, cadmium, chromium, nickel, oil products can also trigger lung cancer.

If moving in a place prone to exposure to these chemicals, be sure to wear a mask or other personal protective equipment in accordance with health and safety standards.


Lung cancer can also be caused by gene changes or DNA mutations associated with heredity.

Patients with lung cancer can inherit certain DNA changes in the source of this cancer.

People who have parents or siblings of patients with lung cancer are more at risk of developing this disease.

What does lung cancer feel like?

After knowing the causes of lung cancer, also recognize the symptoms of this dangerous disease.

Launching Mount Sinai, the characteristics of lung cancer that are often felt include:

  • Chest pain

  • Cough never goes away

The later stages of lung cancer are often accompanied by symptoms of bone pain, loss of rum, joint pain, shoulder pain, difficulty swallowing, swollen face and arms and loose body.

Lung cancer can be detected by physical examination, x-rays or computed lung tomography.

If you find the characteristics of lung cancer above, immediately consult a doctor. The sooner the disease is detected, lung cancer is easier to treat.

How to prevent lung cancer?

Some risk factors that can increase a person's chances of developing lung cancer, such as heredity, cannot be controlled.

However, most of the causes of lung cancer come from external factors such as exposure to cigarette smoke, vaping, radon gas, air pollution, to harmful chemicals.

To prevent this disease, you can control some of the risk factors above by quitting smoking, not being in a smoking environment, not using vaping, and minimizing exposure to air pollution as much as possible.
