Testosterone and Breast Cancer and Breast Cancer Increase

Copyright 2005, James Michael Howard, Fayetteville, Arkansas, U.S.A.

I suggest the pattern of cancer incidence reported by Hall, et al.,
(Urbanization and Breast Cancer Incidence in North Carolina, 1995-1999; Ann
Epidemiol. 2005 May 25), that breast cancer may be higher in urban counties and
that "These results suggest that there are urban effects that influence the
incidence of lung cancer that are not explained entirely by smoking behaviour."
(Soc Sci Med. 2005 Jun;60(12):2833-43. Epub 2005 Jan 21) may be explained by
testosterone levels. It is my hypothesis (1994) that high testosterone is
involved in initiation of female breast cancer, as well as other cancers, male
and female, (Annals of Internal Medicine 2005; 142: 471-2). A report comparing
rural areas and a large city found that testosterone is higher in the large city
(Folia Histochem Cytobiol. 2001;39 Suppl 2:38-9).

I suggest the pattern of cancer incidence reported in the article may be due to
the effects of higher levels of testosterone in urban populations. Also, it is
my hypothesis that the "secular trend," the increase in size and earlier puberty
in children is caused by an increase in the percentage of individuals of higher
testosterone within populations with time. Therefore, as this percentage
increases with time, cancer also increases.
