Factors Trigger the onset of Lung Cancer


Factors Trigger the onset of Lung Cancer, smoking and exposure to certain chemicals may increase the risk of developing lung cancer. Doctors and health experts believe that smoking is a major cause of lung cancer.

Lung cancer is caused by mutations in your DNA. When cells reproduce, they divide and replicate, forming cells are identical, so that your body is constantly renewing itself. Inhalation of hazardous substances or substances cause cancer (carcinogens) such as cigarette smoke, asbestos, radon, and can damage the cells that line your lungs.

At first your body may be able to repair itself. With repeated exposure to Your cellsbecome increasingly damaged. Over time, the cells start acting normal and grow uncontrollably. This is how cancer can develop.

Some precancerous changes must occur before the cancer becomes a reality. The extra cells buildup causes tumors, either benign or malignant. The tumor is malignantcancer of the lung can be life threatening. They can spread and even returned afterthey have been deleted. According to the Center for disease control and prevention(CDC), almost 90 percent of all lung cancers are caused by smoking.

The following factors trigger the occurrence of lung cancer:

Genetic Factors

Current research shows that if your family members (mother, father, sibling, aunt, uncle, or grandparent) has lung cancer, you might have a slightly higher risk of illness.This is true even if you don't smoke. It is unclear whether genetics cause lung canceror just increase Your vulnerability to the disease.

The age of

According to the American Cancer Society (ACS), lung cancer mostly occurs in olderadults. Two of the three people who are diagnosed with lung cancer is around age 65 or older. The average age at time of diagnosis is about 70 years old. The older you are, the longer you have been exposed to harmful chemicals. This naturally increases the risk for cancer.

Pulmonary Disease In The Past

Lung disease you've suffered in the past, such as tuberculosis, and chronic obstructive pulmonary disease (COPD), chronic bronchitis and emphysema, can cause inflammation and scarring in the lungs. You may be at greater risk of lung cancer if you have a history of chronic disease that affects the lungs.

Radiation Therapy To The Chest

radiation therapy is used to treat another cancer such as lymphoma and breast cancer non-Hodgkin's can increase the risk of lung cancer. This risk is higher if you smoke.


Smoking is the number one trigger factor for the occurrence of lung cancer, in fact it covers almost 90 percent of all cases. Smoking and cigarette smoke contains more than 7000 chemicals (such as oxides of nitrogen and carbon monoxide), many of which are carcinogenic. Inhaling the chemicals in cigarettes immediately triggers changes in lung tissue.

Exposure To Cigarette Smoke

Even if you don't smoke, who are exposed to cigarette smoke in the home, workplace, or in the restaurant and bar can increase the risk of lung cancer. According to the CDC, each year approximately 3000 people in the United States who had never smoked died of lung cancer because cigarette smoke.


A balanced diet gives your body the vitamins and minerals needed to maintain good health. If you don't eat a mixture of diverse healthy food, like fruits and vegetables, you may have an increased risk for lung cancer. This is especially true if you are a smoker.

That's the factor triggering the onset of lung cancer that you can know. Once you know the cause, it's good that you also know the traits of cancer of the Lung in order to make it easier to recognize the disease in this one. Thus, you will also be easier totreat it.
