Screening for lung cancer is by and large an expensive and time-consuming process which can only be done by larger medical facilities. But Nanjing doctors now look set to change all that, with a new procedure involving just one small vial of blood.
总的来说，肺癌筛查是一个昂贵且耗时的过程，只能由较大的医疗机构来完成。但南京医生现在似乎准备改变这一切，他们推出了一种只需要一小瓶血液的新手术。
Lung cancer kills more people than any other cancer. According to the latest global cancer statistics released by the World Health Organisation in 2020, there were 9.96 million cancer deaths worldwide that year, among which 1.8 million were from lung cancer.
肺癌比任何其他癌症杀死的人都多。根据世界卫生组织发布的2020年最新全球癌症统计数据，当年全球有996万人因癌症死亡，其中180万人死于肺癌。
In fighting that, scientists and clinical experts believe that early detection, diagnosis and treatment of lung cancer are essential to prolong survival of patients, reduce economic burden and improve quality of life.
为此，科学家和临床专家认为，肺癌的早期发现、诊断和治疗对于延长患者生存、减轻经济负担和提高生活质量至关重要。
