癌症防治重在“三早”

The Significance of Secondary Prevention of Cancer in China

1973～ 1992的 20年间 ,我国癌症死亡率呈明显上升趋势。在肿瘤防治策略中，一级预防的重要性毋庸置疑，但一般需时较长，受益者为年轻群体。而体现"早期发现、早期诊断及早期治疗"的二级预防有可能在较短时期内降低癌症的死亡率，甚或发病率。这将有利于地区社会及经济发展，从而提高社会医疗保障水平。在宫颈、食管、胃、肝及鼻咽等肿瘤的高发现场，可将二级预防作为当前肿瘤控制的重要手段加以推行。

During past twenty years (1973～ 1992), the cancer mortality was increasing significantly in China. For cancer prevention and control nationwide, the primary prevention is important. Pity is that it usually takes longer time to decrease cancer mortality and liable to benefit younger generation. In practice, the secondary prevention, which put emphasis on the massive screening, early detection and early treatment, would decrease the cancer mortality as well as cancer incidences in relatively short time. Therefore, it would contribute much to the local social and economic development and improve the health insurance. In the high risk areas of cancers, such as cervical, esophageal, gastric, liver and nasopharyngeal cancers, the secondary prevention could be carried out as more effective strategy for cancer prevention in China.
