近年来肺癌的发病和死亡率均明显上升,已被称为多发常见肿瘤之一。据第十二届国际癌症大会报告肺癌发病与死亡率在两性均急剧上升;英国、加拿大、美国、西德、奥地利、比利时、丹麦、荷兰和法国肺癌死亡率占男性恶性肿瘤首位;女性以美国、英国和荷兰增加为著;日本近10年肺癌死亡也增加5倍之多。肺癌死亡率在我国北京市居首位,上海和武汉居第二位,吉林占第三位。当前防治肺癌的首要问题仍是缺乏有效的早期诊断方法。有人报告肺癌误诊率高达41.7％,误诊期最短30天、最长达28个月之久,这对防治颇为不利。
In recent years, the incidence and mortality of lung cancer have increased significantly and it has been called one of the most common tumors. According to the report of the 12th International Conference on Cancer, the incidence of lung cancer and mortality have risen sharply in both sexes; lung cancer mortality in the United Kingdom, Canada, the United States, West Germany, Austria, Belgium, Denmark, the Netherlands, and France accounted for the first place in male malignancies; women in the United States , Britain and the Netherlands increased; Japan’s lung cancer deaths in recent 10 years also increased by five times. Lung cancer mortality ranks first in Beijing, with Shanghai and Wuhan ranking second, and Jilin third. The current primary problem in the prevention and treatment of lung cancer is still the lack of effective methods for early diagnosis. Some people have reported that the rate of misdiagnosis of lung cancer is as high as 41.7%, and the period of misdiagnosis is as short as 30 days and as long as 28 months, which is quite unfavorable for prevention and treatment.
