How will things progress with cancer? Main facts: cancer increase until 1964. Reversal of sexual proportion (now greater mortality of men). Cancer of different organs changing their relative frequency. In 80% cancer acquired. Enviromental carcinogenes. Percental increase of cancer without carcinogenes by decreasing causes of death (infectious diseases). Future problem: Experimental cancer prevention (tests upon germinal cells for mutagenicity). Since 1964 the level of cancer mortality has remained constant. Decrease is in sight: an anti-cancer future has begun.
癌症的情况将如何发展？主要事实：癌症发病率在1964年之前持续上升。性别比例发生逆转（现在男性死亡率更高）。不同器官的癌症其相对发病率在变化。80%的癌症是后天形成的。环境致癌物。由于死亡原因（传染病）减少，无致癌物情况下癌症的百分比增加。未来问题：实验性癌症预防（对生殖细胞进行致突变性测试）。自1964年以来，癌症死亡率一直保持稳定。下降在望：抗癌的未来已经开始。
