随着工业发展、环境污染、吸烟人群增加,肺癌的发病率及死亡率都已位居所有恶性肿瘤的首位,成为严重危害人类健康的杀手。早发现、早治疗是提高肺癌患者生存率的关键。常规肺癌检测方法不能用于大范围高危人群筛查,需要一种无创、快捷的肺癌诊断方法。 With the industrial development, environmental pollution, smoking population increase, the incidence of lung cancer and mortality rates have become the first place of all malignant tumors, a serious threat to human health killer. Early detection and early treatment is the key to improve the survival rate of patients with lung cancer. Conventional lung cancer detection methods can not be used for screening a wide range of high-risk populations, requiring a noninvasive and rapid diagnostic method for lung cancer.
