"Lung cancer buff," the late Shin Sung-he quit smoking 35 years ago

The late Shin Seongil kept his body steady for his health and kept his alcohol and cigarettes away. "I really hate people who smoke," he answered in a question about his health secrets in 2013. His wife, Amanran, was a smoker and expressed his concerns. "I've always thought about health," said his wife, actor Ahn An-ran. "I started a day earlier than anyone and I lived very hard."

The deceased died of "lung cancer". He received chemotherapy treatment at a medical facility after receiving the third term of lung cancer last June. At the time, Amanran said, "I can not believe that my husband who does not smoke is lung cancer," he said. "I would like to be able to get back to health as soon as bad cancer has been defeated."

The deceased did stop smoking in 1982. I have been smoking for 35 years. He is increasingly aware of lung cancer since the announcement of his death.

The precise cause of lung cancer in the deceased is unknown, but there is an badysis that genetic factors have acted more than environmental factors. The father of the deceased died of tuberculosis. "I had to quit smoking in 1982, but I had to be careful because of paternal genes," said the deceased on one of the broadcasts, stating, "One day, my cough got worse, .

Smoking is the leading cause of lung cancer. In studies conducted at home and abroad, about 85% of lung cancers are thought to be caused by smoking. Smoking increases the risk of lung cancer by 13 times. Long-term exposure to second-hand smoke increased the risk of lung cancer 1.5-fold. One study found that men who smoked twice as much cigarettes every day for 20 years were 60 to 70 times more likely to die of lung cancer.

Patients with lung cancer do not show any symptoms at first, but after some degree of cancer, cough worsens and sputum mingles with blood (phlegm), dyspnea, chest pain and hoarseness. Headaches, nausea and vomiting are also common symptoms of patients with lung cancer.

Lung cancer is considered a cancer with a low survival rate. According to the results of the "Third Assessment of Lung Cancer" published by the National Health Insurance Review and Assessment Service last April, 43.7% of lung cancer cases were discovered during the fourth period, when the cancer was transferred to other organs. Small cell lung cancer, which accounts for 17.2% of all lung cancers, accounted for 70.3% of cases in which the tumor was metastasized to the opposite lung or to other organs.

Lung cancer is diagnosed by X-ray of the chest. In addition, computerized tomography (CT) using contrast media can provide more accurate results. Patients with lung cancer receive chemotherapy if they are in good physical condition. However, the one-year survival rate is 30-35%. If the condition of the disease is so severe that it is difficult to receive chemotherapy, the average survival time is 4 to 6 months and the 1 year survival rate of 5 to 10%.

Lung cancer has a low survival rate, but treatment results improve thanks to immunotherapy. Anti-cancer immune medications are activated by immune cells that are suppressed by cancer cells and cancer cells are attacked. Two US and Japanese scientists who laid the groundwork for the development of immunocompromised anti-cancer drugs in October were awarded the Nobel Prize in Physiology.
