Estrogen Receptors In Breast Cancer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Tamoxifen is given to breast cancer patients to suppress estrogen or both estrogen & progesterone?
Estrogen: Tamoxifen is given to individuals with specific breast cancers that are driven to grow by the presence of estrogen receptors. Tamoxifen interferes with the activity of estrogen in the breast, preventing cancer growth. The role of Progesterone receptors is unclear, though Progesterone receptors in breast cancer are generally associated with estrogen receptors, making tamoxifen an effective therapy. ...Read moreSee 2 more doctor answers
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

Also depends on your preference and overall health condition. Different test like oncotype dx, mammaprint can give you more info-re- recurrence risk of cancer and will be helpful in choosing the right therapy for you.D/w your md. ...Read moreSee 2 more doctor answers
Hormone replacement therapy. Estrogen alone increases risk of uterine cancer. Adding progesterone increases risk of breast cancer, but reduces risk of uterine cancer. What's the right balance?
Individual: Yes, estrogen alone does increase the risk of uterine cancer over time. And yes the whi showed that the combination of a certain synthetic estrogen and a certain synthetic progestin increased the risk of breast cancer. But most specialists do not use those older types of synthetic hormones and with newer medications the risks are lower and different. So a balance can be achieved. ...Read more
Does nolvadex (tamoxifen) increase testosterone and increase the rate of division in cancer cells?
Yes and no: Nolvadex, aka tamoxifen is a very weak estrogen. In men it will make the brain think you have too little estrogen so the brain asks the testicles to make more testosterone that can be converted into estrogen later. In men and women, tamoxifen will block estrogen which can help treat breast cancer. ...Read more
YES for ER positive: Oopherectomy has been proven to reduce recurrence in estrogen-receptor positive pre-menopausal women. Prior to tamoxifen, it was a commonly used treatment for metastatic disease and is now known to reduce recurrence in high-risk premenopausal hormone-receptor positive breast cancer, even without the use of other endocrine therapies. ...Read moreSee 3 more doctor answers
Sort Of: We define cancers by their organ of origin. Therefore, by strict definition, bone cancer originates from bone cells; Anastrozole won't help these rare cancers. More commonly, cancers can spread to bones--we call this bone metastasis. Breast cancer can spread to bones; anastrazole can prevent the spread of certain breast cancers. Hope this helps. ...Read more
Estrogen/Uterine CA: Absolutely not. "high" estrogen levels are only one factor in the risk profile for uterine cancer, which also includes obesity, family history, and oral contraceptive history. Even if you possess one or more risk factors, that does not mean that a tumor is certain. Close monitoring and counselling by your gyn is the best course of action. ...Read more
Is arimidex (anastrozole) when given as prevention of recurrence of breast cancer only used with estrogen receptive cancer?
Yes*: Arimidex (anastrozole) belongs to a category of drugs called aromatase inhibitors. These are effective chemotherapeutic agents for people with either estrogen-sensitive or *progesterone-sensitive breast cancers. This is only effective after menopause; premenopausal women may use tamoxifen for a similar response rate. ...Read moreSee 1 more doctor answer
Would metastatic cervical cancer in the breast appear the same as breast cancer on mammogram and ultrasound?
Possibly on imaging: Cervical cancer (the tissue at the end of the vaginal canal) rarely metastasizes to the breast. Rather breast cancer may metastasize to many areas of body, such as bone, lung, brain, lymph nodes. That being said, any abnormal growth in the breast, though mostly breast tissue, could look similarly by mammogram or ultrasound. The bottom line is if there is an abnormality, must be biopsied. ...Read moreSee 2 more doctor answers
An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one ...Read more
Most breast cancers are carcinomas. This is a type of breast cancer. These cancers start in the cells that line organs and tissues. In fact, breast cancers are often a type of carcinoma called adenocarcinoma, which starts in cells that make glands (glandular tissue). Breast adenocarcinomas start in the ducts (the milk ducts) or ...Read more
