The World Health Organization predicts that the number of annual cancer deaths will grow by 45 % over the next 20 years, from the current level of roughly 8 million worldwide to 11 million. Even if advances in medical treatment allow most cancers to be cured, such cures are likely to require early detection.
世界衛生組織預估 20 年後，全球癌症死亡人數將呈 45 % 的成長，由目前每年約 800 萬人，大幅增加至 1,100 萬人；即使拜醫療進步之賜，大部分的癌症可被治癒，但前提仍是「早期發現」。
