近年来,世界各国随着工业发展,肺癌的发病率有逐年增加的趋势,成为人类健康和生命的一大威胁。由于早期肺癌缺乏典型症状,虽有咳嗽、胸痛、痰血等,但常不引起患者的注意,X线表现往往不典型,故诊断易被延误。现对近七年来我们收集72例肺癌的X线征象作一分析,以期提高在胸部平片对肺癌的认识,并重点讨论肺癌的平片诊断问题。 In recent years, with the development of industry in all countries of the world, the incidence of lung cancer has increased year by year, becoming a major threat to human health and life. Due to the lack of typical symptoms of early lung cancer, despite cough, chest pain, blood stasis, etc., but often do not cause the patient’s attention, X-ray findings are often not typical, so the diagnosis is easily delayed. Now we analyze the X-ray signs of 72 cases of lung cancer in the past seven years in order to increase the awareness of lung cancer in chest plain films and focus on the diagnosis of plain lung cancer.
