It is reported that since 1990s, many studies have claimed that drinking too much milk may induce male breast cancer, ovarian cancer and prostate cancer.

Excessive drinking may induce cancer.

A study published in the New England Journal of Medicine from June 5, 2004 to 10 pointed out that milk may be an important inducing factor for female breast cancer.

Researchers from Denmark surveyed 1 17000 women and found that the growth rate of adolescent girls aged 8- 14 has a great influence on the incidence of breast cancer in their adulthood. The incidence of breast cancer in adolescent girls who are tall and thin is significantly higher than that in girls who are short and fat.

The research shows that the incidence of breast cancer in girls who reach the peak at 13 ~ 14 years old is lower than that in girls who reach the peak at10 ~1year old 16%.

Researchers believe that drinking a lot of milk will increase the level of insulin-like growth factor -I (IGF-I) in human body, and IGF-I is closely related to taller body. Many studies have shown that almost every cancer is related to IGF-I, which is a key factor to promote the growth and reproduction of cancer cells.
