The death rate from breast cancer among females in England and Wales which had been falling during 1951-59 at ages before 45 increased from 1960 to 1967; and at ages 45-64 there has been a progressive increase ever since 1955. Regional rates at the early ages were considerably higher in Greater London than in the north until 1961, but the difference then gradually disappeared; and at higher ages an excess in the south over that in the north and Wales has persisted at ages 45-64.Whilst the total mortality from breast and uterine cancers combined has shown little regional variation, the proportion of breast cancer in the total has been consistently higher in the south than in the north, and possible implications of this are discussed. Breast cancer rates in the regions are positively associated with the dietary intake per person of butter, cheese, liquid milk and green vegetables but this in itself does not prove a causative connection.
1951年至1959年间，英格兰和威尔士45岁以下女性的乳腺癌死亡率呈下降趋势，但在1960年至1967年有所上升；45岁至64岁年龄段的乳腺癌死亡率自1955年以来一直在逐步上升。直到1961年，大伦敦地区低年龄段的发病率一直远高于北部地区，但这种差异随后逐渐消失；在较高年龄段，45岁至64岁之间，南部地区的发病率一直高于北部和威尔士。虽然乳腺癌和子宫癌的总死亡率在地区上差异不大，但南部地区乳腺癌在总数中的比例一直高于北部地区，本文讨论了这一现象可能产生的影响。各地区的乳腺癌发病率与人均黄油、奶酪、液态奶和绿色蔬菜的摄入量呈正相关，但这本身并不能证明存在因果关系。
