Studies have also shown that a woman’s risk of breast cancer is related to the estrogen and progesterone made by her ovaries (known as endogenous estrogen and progesterone). Being exposed for a long time and/or to high levels of these hormones has been linked to an increased risk of breast cancer.
How does estrogen cause cancer?
It is seen in women who take estrogen only and still have a uterus. This is due to estrogen’s effect on this lining, which builds up with prolonged estrogen stimulation. When this occurs, endometrial hyperplasia can result. This cancer was also monitored in the Women’s Health Initiative.
Can taking estrogen cause breast cancer?
Estrogen-only HRT increases the risk of breast cancer, but only when used for more than 10 years. Estrogen-only HRT also can increase the risk of ovarian cancer. The higher breast cancer risk from using HRT is the same for so-called “bioidentical” and “natural” hormones as it is for synthetic hormones.
Is estrogen positive breast cancer slow growing?
Estrogen receptor/progesterone receptor (ER/PR) positive breast cancers tend to grow more slowly than ER/PR negative cancers, and are more likely to respond to hormone therapy.
Can low estrogen cause cancer?
This analysis found that women who took estrogen after menopause did have an increased risk of getting ovarian cancer. The risk was highest for women currently taking estrogen, and decreased over time after estrogen was stopped.
Does cancer feed on estrogen?
Not all cancers are fueled by hormones. But a few types can be, such as: Breast cancer. Some types need estrogen and progesterone to grow.
What is the success rate of hormone therapy for breast cancer?

How can I flush excess estrogen?
Exercise regularly. Research suggests that exercise can help to reduce high estrogen levels. Premenopausal women who engage in aerobic exercise for five hours a week or more saw their estrogen levels drop by nearly 19%. Cardio exercise helps the body break estrogen down and flush away any excess.

How does a woman’s weight influence her breast cancer risk?
Being overweight also can increase the risk of the breast cancer coming back (recurrence) in women who have had the disease.
