4 Mandatory Facts to Know about Lung Cancer

The World Health Organization (WHO) estimates that there are around 1.7 million people in the world who die of lung cancer per year.

This number is more than the death of colon, liver and breast cancers as reported by WHO’s official website, Wednesday (10/10/2018).

Here are four facts that must be known about lung cancer collected from various sources.

1. Cigarettes are the main cause of lung cancer

The pulmonary specialist at RSUP Persahabatan, Jamal Zaini, said around 80 percent of lung cancer patients were smokers. In cigarettes, Jamal said, there is tar which is damaging to the respiratory tract including lung tissue. When the airways are exposed to harmful substances from cigarettes, their long-term effects cause cancer.


“Initially it damaged the epithelial cells, then the function was damaged, then it became cancerous,” Jamal said when talking to reporters at RSUP Persahabatan Jakarta some time ago.

Cigarettes are not the only cause of lung cancer. There are several other factors that can cause lung cancer, such as air pollution, living in a factory and mining environment, age above 40, and family history.

2. Passive smoking, susceptible to lung cancer

The longer passive smokers are exposed to carcinogens (substances that cause cancer) from cigarettes, the greater the risk of developing lung cancer, as said lung specialist Feni Fitriani Taufik.

3. Lung cancer is often found in advanced stages

Symptoms of lung cancer are not typical, namely coughing, shortness of breath and chest pain. So that this disease is often found to be advanced stage 3 and 4.

“Usually come to check up, if there have been complaints or spreads usually come because of that,” said pulmonary specialist at the Friendship Hospital in Jakarta, Elisna Syahruddin told Liputan6.com via telephone some time ago.

4. Early detection of lung cancer by routine check

Considering the symptoms of lung cancer that are not typical, Elisna advised to do a lung examination once a year. In people who have many risk factors it is advisable to control more often than those who do not have many risk factors.

Some risk factors include age above 40, exposure to cigarette smoke, air pollution, living in areas near factories or mining, and family members having a history of cancer.
