Breast cancer : how long and how much exposure to the pill or hormone treatment causes it?

Pill OK ERT not sur. Most studies show that birth control pills do not increase the risk of breast cancer. Prolonged usage of post-menopausal ert probably increases risk. For most women short term ( a few years) of ert to help menopausal symptoms is probably safe (unless you are at high risk), but i recommend decreasing dosage after 2-4 years and trying to get off estrogen altogether unless symptoms are intolerable.
Small risks. The birth control pill for a premenopausal woman and hormone therapy for a postmenopausal woman are completely different situations. In the former there is no increased risk of breast cancer. In the latter there is probably a small measurable increased risk after 4 years but it is not clear how that is affected by the types and routes of administration of the estrogen and progesterone.

Are the risks of getting cancer (especially breast cancer) higher, if I am already on hormone treatment (estrogen and progestogen) at age 17?

Family practice . Tell us why you are on hormone replacement therapy. Did they remove both ovaries or are they nonfunctional. Not higher risk for breast cancer. Slightly higher risk for blood clots. Don't smoke and exercise regularly. Read more...
No. Hormone use as birth control is not felt to increase the risk of developing breast cancer. It is the use of hormone replacement after menopause that is the concern. Read more...

Hormone therapy for menopausal symptoms cause breast cancer?

NO BUT INCREASE RISK. Hormone therapy does not cause breast cancer but it does increase your risk of breast cancer. According to the national nurses health study using hormone replacement therapy for 10-15 yrs increases risk about 20%, if used more than 15 yrs it doubles to around 40%. Talk to your doctor to help you decide how to better manage postmenopausal symptoms. Read more...

Does hormone replacement therapy for menopausal symptoms cause breast cancer?

It can. The cause of breast cancer is so complex and poorly understood that it's better to talk about "associations" rather than "causes". Studies have shown that women who have used hormone replacement have a slightly higher incidence of breast cancer as compared to women that have not. In general, if you can avoid it, it's better to, especially if you have other risk factors for breast cancer. Read more...
In short, no. There are three human esrogens: Estradiol (from the ovary), estriol (from the placenta in pregnancy) and estrone (from peripheral fat conversion). Estrone is probably the culprit since women with excess peripheral body fat have increase rates of estrogen related cancers (breast, uterus, ovary, colon). Many oral estrogen hormones on the market are converted to estrone in the liver. Read more...
Increases risk. Hormone replacement therapy (hrt) has been shown to increase one's risk for breast cancer if taken for longer than 5 years. The current recommendation is to take low doses for a limited amount of time and then stop. There are some other non hormonal medications that can be used to help manage menopausal symptoms. Read more...
Depends. Virtually all of the studies showing that hrt increases breast cancer have been done on premarin (conjugated estrogens). Premarin (conjugated estrogens) is converted to estrone in the liver when taken orally. Overweight women convert adrenal hormones into estrone in peripheral body fat & have increased rates of estrogen dependent cancers (breast, colon, uterine). I suspect the culprit is estrone, not estradiol/estriol, the other human estrogens. Read more...

How will I know breast cancer hormone therapy is working?

Depends on situation. If you are receiving hormonal therapy for metastatic breast cancer you will hopefully notice improvement in symptoms from the cancer or by seeing an improvement on another scan. If you are taking hormonal therapy to minimize the chance of recurrence, there is no way to know how well it is working for you as an individual. However, many studies prove that it decreases the chance of recurrence. Read more...

Does postmenopausal hormone therapy lead to breast cancer?

Yes, it can. While not every woman who takes hormone replacement therapy will get breast cancer, there is compelling evidence that it's use substantially increases the risk of breast cancer. A landmark study published last decade sponsored by the national cancer institute found a 25% increase in breast cancer in women who took estrogen and progestin. Read more...
Very low Risk. With due respect. The landmark study, whi, is called into question in so many ways. The nih spent millions to answer very little. As an re, i feel there are many facets to HRT and a careful and comprehensive evaluation of the literature supports a very minimal at best increase in breast cancer and the evidence points to the progestin component only (provera). Consultation warranted. Read more...
Controversial. Hormone therapy can be estrogen only or combination estrogen &progesterone (ep). Almost all studies show an increase in breast ca in women who take ep. There may be more breast ca dx/'d in women who take e, but diagnosed earlier 7 more curable. Some type of Progesterone is indicated in women w/ a uterus to prevent uterine ca. Read more...

Is it true that female hormone therapy can increase the risk of breast cancer?

Yes. Certain hormones, especially longer use of estrogens, can increase a person's risk of breast cancer. Estrogen is listed as a known carcinogen on the fda web site & there is a class action lawsuit ongoing against premarin (conjugated estrogens). See site: http://m.Cancer.Org/cancer/cancercauses/othercarcinogens/generalinformationaboutcarcinogens/known-and-probable-human-carcinogens. Read more...
Very likely. There is considerabel evidence that estrogens(female hormone) plays an important role in genesis of breast cancer. This was best shown in women who took hormone replacement therapy(hrt) after menopause. So such therapy(hrt) is now discouraged whenever possible. Read more...

Does hormone replacement therapy increase your chances for breast cancer expotentionally?

Not exponentially. Data from the whi (women's health initiative) study show that estrogen alone does not significantly increase the risk of breast cancer, especially if started within 5 years of menopause. However, estrogen + Progesterone (needed when women still have a uterus to prevent uterine cancer) increases the risk of breast cancer to about 2x the baseline risk. Progesterone appears to be the "bad guy". Read more...
No. But long-term exposure is probably assocaited with a greater risk of breast cancer. But the actual risk is hard to prove and is certainly not exponential. Still, best not to take ert for more than 5 years unless you are very sympomatic from menopausal symptoms. Read more...
Absolutely Not. The whi as now reviewed was a very poor study overall and likely answers few clinical questions. I agree with the former answer that the progestin component was implicated but would not implicate Progesterone specifically. It was provera, (medroxyprogesterone) a synthetic Progesterone used in the study. The study population does not represent the typical patient we see. You need a consultation with hormone dr.
