Receptors for the female hormones estrogen and progesterone play a key role in breast cancer. These receptors are the eyes and ears of the cells, receiving and interpreting messages sent by the hormones. Estrogen and progesterone stimulate growth of normal breast cells as well as some breast cancer cells. Previous research has shown a connection between hormone levels and the risk of breast cancer in postmenopausal women.

Blood samples were collected from the participants. Of the women in the study, 322 cases of breast cancer were reported. Researchers looked at the different types of cancer and the hormone levels to determine if there was an association.

Researchers say they observed a direct association between breast cancer risk and the level of both estrogens and androgens and in the patients with estrogen and progesterone positive receptors, there were higher sex hormone levels. Thus researchers conclude that higher levels of sex hormones may be strongly associated with the risk of estrogen and progesterone positive breast tumors.
