(HealthDay News) -- A treatment that helps prevent one type of breast cancer in women with an evaluated risk of the disease also appears to help doctors make an earlier diagnosis of another form of breast cancer, a new study reports.

Tamoxifen previously had been shown to reduce the risk of estrogen receptor (ER) positive breast cancer in women at high risk of the disease, but not to affect the chance of developing ER-negative disease.

MONDAY, Sept. 8 (HealthDay News) -- Women who take hormones to relieve symptoms of menopause have a higher risk of developing symptoms of gastroesophageal reflux disease (GERD).

Also, women who use selective estrogen receptor modulators (SERMs), used to treat breast cancer and osteoporosis, also have a higher risk of developing reflux, according to a study in the Sept. 8 issue of the Archives of Internal Medicine.

TUESDAY, Sept. 2 (HealthDay News) -- Contrary to previous study results, the cancer prevention drug anastrozole does not appear to cause impairment of cognitive performance, a new study found.

Anastrozole has been shown to be superior to tamoxifen in preventing breast cancer recurrence in postmenopausal women. But some "cross-sectional" studies have suggested that endocrine therapies such as anastrozole are associated with poorer performance on verbal memory and processing tasks.

Acupuncture helped relieve hot flushes in women taking the drug tamoxifen after breast cancer surgery, says a Norwegian study.

Dr. Harness, President American Society of Breast Surgeons explains Taxoifen and the side effects.

Hi Michelle- Over the summer I had a lumpectomy due to estrogen-receptive Breast Cancer and I'm wondering if you might know an excellent doctor who has experience treating women with Tamoxifin substitutes that are natural such as Indole 3 Carbinol? We have been given contradictory advice by nutritionists, chiropractors, physicians and oncologists about how to successfully lower my estrogen. Warmly, Barbara in Thousand Oaks, CA
