The possible role of female sex hormones in milk from pregnant cows in
the development of breast, ovarian and corpus uteri cancers.

The continued increase in incidence of some hormone-related cancers
worldwide is of great concern. Although estrogen-like substances in
the environment were blamed for this increase, the possible role of
endogenous estrogens from food has not been widely discussed. We are
particularly concerned about cows' milk, which contains a considerable
quantity of estrogens. When we name cows' milk as one of the important
routes of human exposure to estrogens, the general response of Western
people is that "man has been drinking cows' milk for around 2000 years
without apparent harm." However, the milk that we are now consuming is
quite different from that consumed 100 years ago. Unlike their
pasture-fed counterparts of 100 years ago, modern dairy cows are
usually pregnant and continue to lactate during the latter half of
pregnancy, when the concentration of estrogens in blood, and hence in
milk, increases. The correlation of incidence and mortality rates with
environmental variables in worldwide countries provides useful clues
to the etiology of cancer. In this study, we correlated incidence
rates for breast, ovarian, and corpus uteri cancers (1993-97 from
Cancer Incidence in Five Continents) with food intake (1961-97 from
FAOSTAT) in 40 countries. Meat was most closely correlated with the
breast cancer incidence (r=0.827), followed by milk (0.817) and cheese
(0.751). Stepwise multiple-regression analysis (SMRA) identified meat
as the factor contributing most greatly to the incidence of breast
cancer ([R]=0.862). Milk was most closely correlated with the
incidence of ovarian cancer (r=0.779), followed by animal fats (0.717)
and cheese (0.697). SMRA revealed that milk plus cheese make the
greatest contribution to the incidence of ovarian cancer ([R]=0.767).
Milk was most closely correlated with corpus uteri cancer (r=0.814),
followed by cheese (0.787). SMRA revealed that milk plus cheese make
the most significant contribution to the incidence of corpus uteri
cancer ([R]=0.861). In conclusion, increased consumption of
animal-derived food may have adverse effects on the development of
hormone-dependent cancers. Among dietary risk factors, we are most
concerned with milk and dairy products, because the milk we drink
today is produced from pregnant cows, in which estrogen and
progesterone levels are markedly elevated.
