At present, nearly 70% of lung cancer patients in China are advanced at the time of initial diagnosis, and the 5-year survival rate of advanced patients is less than 5%.
"Most of the early symptoms of lung cancer are not obvious, and most of the patients are in the middle or late stages when they go to see a doctor because of discomfort."
Li junling, chief physician of the cancer hospital of the Chinese academy of medical sciences, said that the incidence of lung cancer is related to age, and the older you are, the greater the probability of the disease.
"Smoking is internationally recognized as one of the most important causes of lung cancer.
But people who don't smoke can still get lung cancer."
Lung cancer is a disease caused by a combination of factors, said li.
Secondly, air pollution, kitchen fume and automobile exhaust are also important factors that cause lung cancer.
In addition, estrogen, overwork, and a family history of lung cancer are all factors.
"Clinically, the trend of younger lung cancer patients has increased."
Li junling, chief physician at the cancer hospital of the Chinese academy of medical sciences, told reporters that lung cancer used to be considered a common disease among the elderly, especially those over 60, but now more and more young people, including some young women, are being diagnosed with lung cancer.
