Velicer, et al., reported that the "Use of antibiotics is associated with increased risk of incident
and fatal breast cancer."

It is my hypothesis (1994) that low dehydroepiandrosterone (DHEA) may trigger oncogenes and that
high testosterone may reduce DHEA, therefore increasing the probability of cancer. Both of these
have since received support. For example, hormone replacement therapy decreases DHEA and HRT has
been found to increase the incidence of breast cancer. Also, consumption of ethanol by women
increases testosterone; alcohol consumption by women has been connected with increased breast
cancer. ("How 'Hormone Replacement Therapy' (HRT) May Cause Breast Cancer" at
www.anthropogeny.com/research.html .)

It is known that DHEA exerts protective effects against many forms of infections, including
bacteria. I suggest the connection of increased breast cancer in women who have required antibiotics
is low DHEA. That is, low DHEA in these women reduced their immune response which subsequently
required the aid of antibiotics. I suggest the increased incidence of breast cancer in these women
is reduced DHEA, not antibiotics.
