The resident female population of Greater Bombay consists of women professing different religious faiths, between which the frequency of breast cancer varies to a great extent. During the 9-year period 1964 to 1972 inclusive, a total of 2130 women with breast cancer were seen, with break-down by religion as follows: Hindus (1259), Muslims (306), Christians (264), Parsi (Zoroastrians) (226), Jains (25), Buddhists (26) and others (24). The average annual age-adjusted (world population) incidence rates, however, were found to be 48.5 and 18.2 per 100,000 in the Parsis and non-Parsis respectively, with an average of 19.9 per 100,000 for the total population. For reasons not yet clear, in every age group the incidence rate in Parsis was 2 to 3 times higher than in the non-Parsis. Time-trend analyses of our data do not reveal any statistically significant increase or decrease in the incidence of breast cancer in any particular age group. Data from death certificates for the same 9-year period show that the age-adjusted mortality rate (world population) is 9.2 per 100,000/year.
大孟买地区的女性常住人口包括信奉不同宗教的女性，其中乳腺癌的发病率差异很大。在1964年至1972年这9年期间（含1964年和1972年），共诊治了2130例乳腺癌女性患者，按宗教分类如下：印度教徒（1259例）、穆斯林（306例）、基督教徒（264例）、帕西人（琐罗亚斯德教徒）（226例）、耆那教徒（25例）、佛教徒（26例）及其他（24例）。然而，年龄调整后的（世界人口）平均年发病率在帕西人中和非帕西人中分别为每10万人48.5例和18.2例，总人口的平均年发病率为每10万人19.9例。由于尚不清楚的原因，在每个年龄组中，帕西人的发病率比非帕西人高2至3倍。对我们的数据进行的时间趋势分析未显示任何特定年龄组的乳腺癌发病率有统计学上的显著上升或下降。同一9年期间死亡证明的数据显示，年龄调整后的死亡率（世界人口）为每年每10万人9.2例。
