最近,国际癌症研究机构和日内瓦世界卫生组织癌症研究单位审查了有关癌症的发病率、死亡率和相对频率的数据。估计出全世界二十四个地区新发病例数。国际癌症统计尚需经过一定时日才能发表,因此,1975年被用作参照年。癌症新发病例的估计数是年590万,可能估计偏低。男性患者中最常见的六种癌症是:肺癌464,000,胃癌422,000,结肠癌和直肠癌251,000,口腔癌和咽癌233,000,前列腺癌198,000,食管癌194,000;女性患者中乳腺癌为541,000名,宫颈癌459,000,胃癌261,000,结肠癌和直肠癌256,000,肺癌127,000,口腔癌和咽癌107,000。上述癌症与肝脏、膀胱、
Recently, the International Agency for Research on Cancer and the Cancer Research Unit of the World Health Organization in Geneva reviewed data on the incidence, mortality and relative frequency of cancer. Estimated number of new cases in 24 regions worldwide. International cancer statistics still need to be published after a certain period of time. Therefore, 1975 was used as a reference year. The estimated number of new cancer cases is 5.9 million years, which may be estimated to be low. The six most common cancers in male patients were 464,000 lung cancers, 422,000 gastric cancers, 251,000 colon and rectal cancers, 233,000 oral and pharyngeal cancers, 198,000 prostate cancers and 194,000 esophageal cancers, 541,000 breast cancers among women, and cervical cancers. 459,000, 261,000 gastric cancer, 256,000 colon cancer and rectal cancer, 127,000 lung cancer, and 107,000 oral and pharyngeal cancers. The above cancer and liver, bladder,
