Dat Nederland bovenaan staat in de lijst van landen waar borstkanker het meest voorkomt ter wereld heeft volgens deskundigen mede ook te maken met de Nederlandse koemelk en de hormonen die daarin zitten.

Er is zo ontzettend veel te vinden over de relatie van hormonen al of niet in melk bij borstkanker, maar misschien kun je dit artikel -

Of deze conclusie van een van de onderzoekers van de Harvard Nurses' Health Study: Is early sexual maturity a bad thing, health wise? Dr.
Catherine Berkey, of Brigham Women's Hospital, Boston,
Massachusetts, examined data from 65,000 participants
in the Harvard Nurses' Health Study.
Her findings were published in the journal Cancer in
1999. Of the participants, 806 developed breast cancer
before menopause and 1,485 developed breast cancer after
menopause. Dr. Berkey's comment:
"Earlier menarche and taller adult height were predictive
of elevated breast carcinoma risk. Our work provided
evidence that breast [cancer] risk is influenced by
preadulthood factors, and thus prevention efforts that
begin in childhood and adolescence may someday be useful."
Of een Japanse studie die aantoonde dat nadat Japan melk ontdekte (1948) de meisjes steeds vroeger gingen menstrueren. Volgens de onderzoekers had dit te maken met de hormonen in melk: There is one country where milk consumption was
unknown before 1946. In Japan, in every year since 1946,
20,000 persons from 6,100 households have been interviewed
and their diets carefully analyzed along with their weights
and heights and other factors such as cancer rates and age
of puberty (the last measured by the onset of menstruation
in young girls). The results of the study were published
in Preventive Medicine by Kagawa in 1978.
In 1950, the average Japanese girl
had her first menstrual cycle at the age of 15.2 years.
Twenty five years later, after a daily intake of estrogen
and progesterone from milk, the average Japanese girl was
ovulating at the age of 12.2 years, three years younger.
Never before had such a dramatic dietary change been seen
in such a unique population study.
