一、实现早期诊断肿瘤的重要性及国内外发展动向癌症仍是当前严重威胁人类健康的疾病之一,我国每年死于癌症的人数约70万,平均不到一分钟就有一人死于癌症。虽然对于中晚期肿瘤病人的治愈率不高,然而对于早期的肿瘤病人的治愈率可高达90％以上。这在国内外的医学文献上均已有报导。因此从当前的防治水平来看,能挽救癌症患者的最有效的方法就是要实现早期发现,早期诊断,早期治疗。 First, the importance of early diagnosis of cancer and the development trend at home and abroad Cancer is still one of the most serious diseases that threaten human health. In China, the number of people who die from cancer is about 700,000 each year. On average, one person died of cancer in less than one minute. Although the cure rate for patients with advanced cancer is not high, however, the cure rate for early cancer patients can be as high as 90% or more. This has been reported in the medical literature at home and abroad. Therefore, from the current level of prevention and treatment, the most effective way to save cancer patients is to achieve early detection, early diagnosis and early treatment.
