There has been a general increase in the incidence of cancer of most major sites during the period 1960-69; this is true even when allowances are made for shifts in the age composition of the population. Improvements in diagnostic procedures may account for some of these increases but it is doubtful that they are solely responsible for the greater incidence recorded.A few sites stand out as being primarily responsible for the increase in the overall cancer incidence. Lung cancer is increasing in both males and females; the rate of increase, however, is much greater among females. It is generally acknowledged that women began smoking cigarettes at a later point in time and to a lesser extent. The pattern which has emerged indicates that females are experiencing a similar trend in lung cancer incidence to that of males. The increase in the incidence of female breast cancer is also noteworthy, although the forces producing this change can only be speculated upon. The high incidence of prostatic cancer among negroes and the increase in the incidence of prostatic cancer in whites are subjects which deserve further investigation, especially since the Alameda County experience is not duplicated in data from the Connecticut Tumour Registry. One of the most encouraging findings is that the incidence of stomach cancer appears to be declining.
在1960年至1969年期间，大多数主要部位的癌症发病率普遍上升；即使考虑到人口年龄构成的变化，情况依然如此。诊断程序的改进可能是这些增长的部分原因，但怀疑它们是否是记录到的更高发病率的唯一原因。有几个部位被认为是总体癌症发病率上升的主要原因。肺癌在男性和女性中都在增加；然而，女性中的增长率要高得多。人们普遍认为，女性开始吸烟的时间较晚，且吸烟程度较轻。出现的模式表明，女性肺癌发病率正经历与男性类似的趋势。女性乳腺癌发病率的上升也值得注意，尽管导致这种变化的因素只能进行推测。黑人前列腺癌的高发病率以及白人前列腺癌发病率的上升是值得进一步研究的课题，特别是因为阿拉米达县的情况在康涅狄格肿瘤登记处的数据中并未重复出现。最令人鼓舞的发现之一是胃癌发病率似乎在下降。
