差不多每个人都经历过这样的事:朋友或亲人被癌症恶魔夺去了生命。由于早期癌症并没有明显的症状和体征,也缺少早期发现的检测手段,等到出现临床症状时,已是中、晚期。即使医生使出浑身解数,往往也只能延长患者的生命或减少其痛苦,只有少数患者可以治愈。癌症的早发现、早诊断、早治疗作为一个世界难题,一直困扰着人们。 Almost everyone has experienced such things: friends or relatives have been taken away by cancer demon. Because early stage cancer has no obvious symptoms and signs, it also lacks the means for early detection. When clinical symptoms occur, it is already in the middle and late stages. Even if doctors try to solve each problem, they often can only prolong the patient’s life or reduce their pain. Only a few patients can be cured. The early detection, early diagnosis and early treatment of cancer have been a problem for the world and have always plagued people.
