Is it safe to take estrogen after breast cancer?
You can work with your doctor to figure out which method best suits your needs. You may be wondering why this form of estrogen could be considered OK for you, since women with breast cancer are cautioned against using estrogen in the form of hormone replacement therapy (HRT). (Visit Hormone Replacement Therapy for more information.) Vaginal estrogen is a local treatment; some estrogen does get into the bloodstream, but the amount appears to be lower than it is with HRT.

Does estrogen increase risk of breast cancer?
Women have different sources (and different levels) of estrogen before and after menopause. So, it’s important to look at studies of estrogen and breast cancer risk by menopausal status. Studies show higher blood levels of the estrogen called estradiol is linked to an increased risk of breast cancer in postmenopausal women.
Can estrogen positive breast cancer be cured?
ER-positive breast cancer has a high chance of being successfully treated, especially when it's discovered early. A diagnosis at a later stage will have a less positive outlook, but being diagnosed at a later stage is less common. There are still many treatment options for late stage cancer.
What causes estrogen receptor positive breast cancer?
Breast cancer cells taken out during a biopsy or surgery will be tested to see if they have certain proteins that are estrogen or progesterone receptors. When the hormones estrogen and progesterone attach to these receptors, they stimulate the cancer to grow.

The risk for recurrence of ER-positive breast cancers persists for a prolonged period, with approximately 50% of recurrences occurring 5 years after initial diagnosis. Results of several randomized trials suggest that extending adjuvant endocrine treatment beyond 5 years can improve disease-free survival (DFS).
Is estrogen positive breast cancer aggressive?
The estrogen activation of ER in ER-positive breast cancers enhances their aggressiveness, while the activation of exogenously introduced ERs into aggressive ER-negative cells diminishes their aggressiveness.
What is the deadliest form of breast cancer?
Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it's found, and is more likely to come back after treatment than other types of breast cancer.

Rare types of invasive ductal carcinoma It occurs when cancer cells within the milk duct of the breast produce mucous, which also contains breast cancer cells. The cells and mucous combine to form a tumor. Pure mucinous ductal carcinoma tends to grow slowly, and has a better prognosis than some other types of IDCs.
What type breast cancer has the highest recurrence rate?
Research suggests that estrogen receptor-positive breast cancer is more likely to come back more than five years after diagnosis. In this study, the researchers looked at the risk of late breast cancer recurrence, meaning the breast cancer came back 10 or more years after diagnosis.
Does estrogen cause cancer to grow?
Estrogen plays a vital role in sexual development and reproductive health. But estrogen is also a carcinogen, which means it has the potential to cause cancer. In estrogen-dependent cancer, estrogen fuels cancer's growth.
Is HER2-negative a good thing?
In normal cells, HER2 helps control cell growth. Cancer cells that are HER2 negative may grow more slowly and are less likely to recur (come back) or spread to other parts of the body than cancer cells that have a large amount of HER2 on their surface.

What is the role of HER2 in breast cancer?
When the mutation is present, the overproduction of HER2 proteins drives the growth of breast cancer cells.
What is adjuvant therapy for cancer?
Adjuvant therapy is usually recommended for large tumors and those with positive lymph nodes (stage II) as well as for tumors that are growing into surrounding tissue and spreading to lymph nodes (stage III). 6 . Metastatic cancer (stage IV) has specific treatment protocols and does not always involve surgery. 7 .
How long does it take to get rid of a tumor after a mastectomy?
Depending on the cancer stage, tumor size, lymph node involvement, and results of genetic testing, adjuvant chemotherapy may be recommended. Treatment typically begins one month after a lumpectomy or mastectomy and continues for around four to six months. 10
What percentage of breast cancer cases are positive for a mutation?
It's believed that around 20-25% of newly diagnosed cases of breast cancers are positive for a genetic mutation that causes HER2 gene amplification. 3 The mutation causes the gene to produce too many HER2/neu proteins (or just HER2 proteins).
How does estrogen help with breast cancer?
Because estrogen encourages hormone receptor-positive breast cancers to grow, lowering the estrogen level can help slow the cancer’s growth or help prevent it from coming back.
What hormones are used to treat breast cancer?
Hormone Therapy for Breast Cancer. Some types of breast cancer are affected by hormones, like estrogen and progesterone. The breast cancer cells have receptors (proteins) that attach to estrogen and progesterone, which helps them grow. Treatments that stop these hormones from attaching to these receptors are called hormone or endocrine therapy.
How long does hormone therapy last after surgery?
Sometimes it is started before surgery (as neoadjuvant therapy). It is usually taken for at least 5 to 10 years.
Does tamoxifen help with ductal carcinoma?
For women who have been treated with breast-conserving surgery for ductal carcinoma in situ (DCIS) that is hormone receptor-positive, taking tamoxifen for 5 years lowers the chance of the DCIS coming back. It also lowers the chance of getting an invasive breast cancer in both breasts.
Can tamoxifen be used for menopause?

What is the primary source of estrogen in the body?
After menopause, fat is the primary source of estrogen production in the body. This means that weight is a critical factor in determining estrogen levels, for both pre and post-menopausal women. Dietary choices and activities that promote a healthy weight are essential to any estrogen-reducing program.
Does fiber help with estrogen?
These are metabolites of the parent estrogen; too much of the 16 AHE is highly stimulatory. A high fiber diet promotes the binding of estrogens in the colon, thus reducing estrogen exposure. Fiber also promotes healthy bacterial populations and enhances satiety, helping to keep weight in a healthy range.
