Study: Nuns Have Greater Cancer Risk
Trends in Mortality in Older Women: Findings from the Nun Study
There are hundreds of articles.
1st study Stated: Breast cancer prevalence could not be ascertained by the national databases so no comparisons could be made.
... only age was significantly associated with breast cancer in the nuns.
The 2nd article is too limited and too early to be of any use:
“TAMPA — Roman Catholic nuns in the United States are at greater risk of developing breast cancer than women in the general population, the University of South Florida reported on Friday.
The study was conducted by two researchers from the university`s College of Public Health. Dr. Robert McDermott and Maureen Malloy polled 345 nuns in Wisconsin and the St. Louis area in 1986 and 1987.”
3rd study is more interesting:
Covers the years 1965 to 1989 which is too early to be of much use for comparing with the BCP population.
But it does address:
The Catholic sisters had high rates of mortality from cancers of the breast and reproductive organs, suggesting an effect ofnulliparity manifested in older women.
BCP impacts wouldn’t be anticipated to manifest in the using population until about 1985.
Today Breast Cancer is far more frequent in the 35-55 age group than it ever was, prior to 1975. The BCP came into wide use after 1965.
