Can early breast development lead to higher risk of breast cancer?

Indirectly. People who go thru puberty at an early age and/or menopause late in life have a slightly higher risk of breast cancer. We believe this is due to prolonged exposure to high estrogen levels.
Probably yes. Breast cancer risk is associated with higher hormone levels, lack of breastfeeding, and no childbearing. Conversely, late age of menarche, pregnancy (especially by age 18), and early menopause reduce the risk of breast cancer, as apparently does breastfeeding. Early breast development would probably mean higher hormones so the risk would be higher. Fibrocystic breast changes also increase risk.

Does early breast development predict if the girl will be buxom?

Not particularly. The timing of first budding, whether on one side or both, does not predict the eventual size/shape or fullness of the breasts. These are determined by a complex interaction of genetic & hormonal factors that come into play later. Read more...

Does taking tamoxifen for breast cancer treatment induce development of cancer of the uterus?

It can. Studies show that women who take tamoxifen have twice the risk of uterine cancer as compared to non treated patients. However, the benefits of tamoxifen for the treatment of breast cancer far outweigh the risks. Aromatase inhibitors are a group of drugs that can be used instead of tamoxifen for post-menopausal breast cancer patients; these drugs do not have this risk. Read more...
Yes. The chance is about 1% and treatment is hysterectomy. With such a low chance then tamoxifen is worth the risk. A gynecologist needs to keep track of the patient and any unusual bleeding evaluated. There are also other hormone alternatives with less risk. Check with your medical oncologist to see which drug is best for a particular patient. Read more...

Will a woman who took the original bc pills have higher risk of breast cancer?

Controversial. Many studies have been published trying to make a connection between bcp use and breast cancer. The two largest studies showed contradictory results, with one noting a slightly increased risk, and the other none. In the former, the risk seemed to go away after 10 years off bcps.

Maybe. The "original" birth control pills, introduced in the 1960's, had a much higher level of hormones compared to modern pills, introduced in the 1980's.The older pills might increase the risk of developing breast cancer, but newer versions have not been shown to significantly increase risk.A decision to take any hormone medication should be made with your physician, taking into account your history.

Had 2 babies in my early 40's. Read that increased risk of breast cancer for 10 years after birth. How much of a risk? Breastfeed both.

Good ; bad news. Waiting until age 40 to interrupt the menstrual cycle with children does increase the risk of breast cancer for women in general.(bad news) the good news is that having a child decreases that risk for you compared to women who have never had children. Nonetheless, check your breasts monthly for "lumps." so that you can be around for high school graduation ceremonies for both of those children. Read more...
