How much does tamoxifen lower breast cancer risk?
Results: Tamoxifen reduced the risk of invasive breast cancer by 49% (two-sided P<. 00001), with cumulative incidence through 69 months of follow-up of 43.4 versus 22.0 per 1000 women in the placebo and tamoxifen groups, respectively.
Does tamoxifen cause cancer?
Because tamoxifen acts like estrogen in the uterus, it can increase your risk of cancers of the uterus, including endometrial cancer and uterine sarcoma. It’s also linked to a higher risk of endometrial pre-cancers. The increased risk seems to affect women over 50, but not younger women.
What is the mechanism of action of tamoxifen?
Tamoxifen (TAM) is known to have a dual mechanism of action: (1) to compete with 17β-estradiol (E2) at the receptor site and to block the promotional role of E2 in breast cancer; and (2) to bind DNA after metabolic activation and to initiate carcinogenesis.
How do I deal with breast cancer?
People with breast cancer often get more than one kind of treatment.
- Surgery. An operation where doctors cut out cancer tissue.
- Chemotherapy. Using special medicines to shrink or kill the cancer cells.
- Hormonal therapy.
- Biological therapy.
- Radiation therapy.
Is there an alternative to taking tamoxifen?
The most popular alternative to tamoxifen is an aromatase inhibitor, such as Arimidex (anastrozole) and Aromasin (exemestane). Other SERMs, such as Evista (raloxifene), and estrogen-receptor antagonists, such as Faslodex (fulvestrant), may also be prescribed instead of tamoxifen.
How common is a second primary breast cancer?

Does tamoxifen affect hair growth?
Tamoxifen, one of the common long-term treatments, can cause hair thinning or loss. It usually levels off after the first year, but it is possible that the thinning can last for as long as you are on the medication. As scalp hair starts growing back, lashes or even eyebrows can still be falling out or slower to grow.
What is the NSABP P-1 data on breast cancer chemoprevention?
NSABP P-1 provides the only data on breast cancer chemoprevention among BRCA1 or BRCA2 mutation carriers. A separately published analysis revealed that of the 288 evaluable NSABP P-1 participants who developed breast cancer, 19 (6.6%) had an associated mutation in BRCA1 (n=8) or BRCA2 (n=11).
What is the NSABP B-27 trial design for breast cancer?
Schema of NSABP B-27 trial comparing neoadjuvant AC to neoadjuvant AC followed by neoadjuvant docetaxel and to neoadjuvant AC followed by adjuvant docetaxel in patients with operable breast cancer (Tam: tamoxifen). Patients were randomized to receive one of three regimens:
What can we learn from the NSABP B-06 trial?
The NSABP B-06 trial, along with other trials conducted by the Milan group to evaluate quadrantectomy, 4, 5 was instrumental in the establishment of breast conserving surgery plus radiotherapy as the preferred method of local treatment for patients with operable breast cancer.
What is the HER2 negative breast cancer research trial?
This research trial studies genetic profiles in blood and tumor samples from patients with estrogen receptor positive and HER2 negative breast cancer that has spread to other places in the body who are receiving palbociclib and endocrine therapy.
