The Causes of Lung Cancer
Adenocarcinoma of the Lungs

What are the proven causes of lung cancer? Air pollution and exposure to radon gas are only some of the reasons but smoking is the number one factor.

Here's a list of potential reasons in adenocarcinoma of the lungs:

1) Smoking

Smoking is a lifestyle-related factor. According to NCI, smoking those cigarettes causes 87% of cases of tumor in the lungs.

The deadly effects of tobacco are major causes of tumor in the lungs. Tobacco contains over 60 carcinogenic chemicals like tar, benzene, arsenic and lead to name a few.

2) Exposure to second hand smoke

Exposure to effects of second hand smoking increases risk for diseases and cancer in the lungs by 24% among non smokers. The lungs of children and the elderly are the most vulnerable.

If you smoke, consider quitting to help prevent damage to your family's lungs.

3) Asbestos fiber

Asbestos is one of the known highly toxic and cancer causing chemicals. It causes diseases and scarring in your lungs.

Exposure to asbestos fiber increases your risk by 5 times more and if you smoke, your risk is 50 to 90 times higher. Other chemicals include chromium, nickel and arsenic.

4) Radon gas

Radon gas emits ionizing radiation which causes cancer such as adenocarcinoma of the lungs.

5) Aging

One of the causes of lung cancer among the elderly is aging. As you grow old, your cells become weak against abnormalities and mutations. Most diagnoses of adenocarcinoma of the lungs are among individuals 65 years old and above.

6) Heredity

Heredity is surprisingly another causal factor in triggering lung tumors. Having a parent or a sibling who died of the disease increases your risk of developing the tumor regardless of whether you smoke or not.

7) Alcohol

Alcohol is not directly associated with lung cancer but it aggravates and enhances the cancerous effects of tobacco. Read how in Dangers of Alcohol.

8) Air pollution

Polluted air is also believed to be what causes adenocarcinoma of the lungs. Air pollution increases your risk similar to that of a passive smoker.

9) Lung diseases

Example of a disease in the lungs that increases your risk for tumor to 4 to 5 times more than that of a non smoker is Chronic Obstructive Pulmonary Disorder or COPD. It is one of the diseases caused by smoking. COPD is also a side effect of a tumor in your lungs.
