HRT-yes: The use of hormone replacement therapy (hrt) for menopause has been shown to increase the risk for breast cancer when used longer than 5 years. Oral contraceptives do not have any relation nor increase in risk of breast cancer.

Yes to a degree: Estrogens are normal to have in the female body. But some women can develop breast cancer particularly due to hormone replacement therapy in older years. Most breast cancers are promoted due to Estrogens especailly taking them as suplemnts for more than 5 years.

5 yrs or less: It has been shown that using hormone replacement therapy (hrt) can increase one's risk of breast cancer when taken for longer than 5 years. Because of this we no longer recommend taking hormones for long periods of time. Work with your gynecologist for options to deal with the symptoms of menopause.

Starve tumor: Many tumors are fed by estrogen - the main female horomone. Anti-estrogen pills block the effects of estrogen (in a variety of different ways) and thereby starve the tumor from a vital growth factor. Even if you are postmenopausal (or even male) your body still produces estrogen in places like the adrenals and subcutaneous fat.
