Complicated: Her-2 is an oncogene usually (not always) associated with er- tumors. We know that it is in general associated with a worse prognosis, but women with her 2+ tumors may respond dramatically to Herceptin (trastuzumab) - a monoclonal antibody. P53 is a tumor suppressor gene. The relationship between p53 and er is currently under study - it may be that p53 mutations may play a role in tamoxifen responsiveness. ...Read moreSee 1 more doctor answer
Is there a benefit to chemotherapy in hormone receptor positive, node positive postmenopausal breast cancer?
Often: There is increasing data based on the oncotype DX test in women with 1-3 positive notes that shows that some women will not get much benefit from chemo and some will get a great deal. It can be useful in cases where a woman is reluctant to take chemo. This is done on tissue that has been already removed. Most oncologists believe that women who have multiple positive nodes should get chemotherapy. ...Read moreSee 1 more doctor answer
Yes: Tamoxifen is an antiestrogen that blocks the ability of breast cancer cells to use estrogen; therefore, it is only effective in hormone sensitive (estrogen receptor +) breast cancers. When taken for 5 years, tamoxifen has been shown to both stop the growth of cancer cells in breast cancer patients and to prevent the development of breast cancer in women that are at high risk. ...Read moreSee 1 more doctor answer
It depends.: Tamoxifen is used to treat hormone-sensitive breast cancer. This is determined by checking for estrogen receptors (er) and Progesterone receptors (pr) on the cancer. If the cancer is er+ and pr- (or vice-versa), it should respond to tamoxifen. However, if the cancer is er- and pr-, tamoxifen is not effective. ...Read moreSee 2 more doctor answers

And new primaries: Tamoxifen blocks estrogen and Progesterone receptors which when stimulated can cause remnant cancer cells to be stimulated to grow back and also can cause normal cells to be overstimulated to develop into new hormonally sensitive cancer. Statistically it reduces the chance of recurrence by 30% and reduces the chance of a second primary by 50%. ...Read moreSee 4 more doctor answers
Simple question from a breast cancer patien, she have only 20mg nolvadex (tamoxifen) and need 10mg a day can she split the 20mg tablet in half?
No.: Male breast enlargement at age 79 is usually due to weight gain and decreasing testosterone, not excess estrogens. Anti-estrogen drugs are not indicated, but full endocrine work up can eliminate hormonal concerns. Gynecomastia is treated with plastic surgery to excise any glandular component (very fibrotic) and liposuction for fatty components. Large breast may require skin removal and tailoring. ...Read moreSee 1 more doctor answer
