Long-term tamoxifen use increases risk of an aggressive, hard to treat type of second breast cancer
While long-term tamoxifen use among breast cancer survivors decreases their risk of developing the most common, less aggressive type of second breast cancer, such use is associated with a more than four-fold increased risk of a more aggressive, difficult-to-treat type of cancer in the breast opposite, or contralateral, to the initial tumor. view more (2009-08-26)
New Cause of Tamoxifen Resistance in Breast Cancer Cells Discovered at Lombardi
When a woman receives a breast cancer diagnosis her entire life may change in the blink of an eye. But the nature of that change is governed by the smallest alterations that take place within the proteins of the tumor cells, determining what treatments she can pursue with a hope of cure and those to which her cancer is resistant. view more (2007-08-13)
Targeting helpers of heat shock proteins could help treat cancer, cardiovascular disease
Dissecting how heat shock protein 90 gets steroid receptors into shape to use hormones like estrogen and testosterone could lead to targeted therapies for hormone-driven cancers, such as breast and prostate, that need them as well, Medical College of Georgia researchers say. view more (2009-06-23)
Molecular imaging holds promise for early intervention in common uterine cancer
A promising new molecular imaging technique may provide physicians and patients with a noninvasive way to learn more information about a type of cancer of the uterus lining called "endometrial carcinoma"-one of the most common malignant female tumors. view more (2009-10-01)
Researchers may have found why women have an edge on salt-sensitive hypertension
Researchers may have found why women have an edge in keeping a healthier balance between the amount of salt they eat and excrete - at least before reaching menopause. view more (2009-01-29)
Study finds hereditary link to premenstrual depression
A specific genetic variation may be tied to an increased risk for severe premenstrual depression, scientists at the University of North Carolina at Chapel Hill and the National Institute of Mental Health have found. view more (2007-07-18)
Preventium is 'where the prevention of breast and prostate cancer begins'
Dr. Ercole Cavalieri and Dr. Eleanor Rogen of the University of Nebraska Medical Center, Eppley Institute for Research in Cancer, located in Omaha, Nebraska, have identified the triggering mechanism by which breast and prostate cancer cells begin. view more (2009-03-17)
Buyer beware: Estrogen supplements not as effective as claimed

First significant genetic finding in severe PMS, or PMDD
The first significant genetic finding in premenstrual dysphoric disorder (PMDD) has now been reported. PMDD is a very severe form of the more commonly known premenstrual syndrome, or PMS. view more (2007-10-03)
Researchers identify cancer preventive properties in common vitamin supplement
Early laboratory research has shown that resveratrol, a common dietary supplement, suppresses the abnormal cell formation that leads to most types of breast cancer, suggesting a potential role for the agent in breast cancer prevention. view more (2008-07-07)
Blood cholesterol levels predict risk of heart disease due to hormone therapy
A new analysis of a subgroup of participants in the Women's Health Initiative (WHI) hormone therapy clinical trials suggests that healthy, postmenopausal women whose blood cholesterol levels are normal or lower are not at increased, short-term risk for heart attack when taking hormone therapy. view more (2008-05-27)
Studies Examine Menopausal Hormone Therapy and Risk of Breast Cancer Recurrence
The doses of estrogen and progestogen used in menopausal hormone therapy may be related to the risk of breast cancer recurrence, according to a new study in the April 6 issue of the Journal of the National Cancer Institute. In 1997, two randomized trials, the Hormonal Replacement Therapy-Is It Safe? (HABITS) trial and the Stockholm trial, began... view more... (2005-04-06)
A diagnosis of triple-negative breast cancer doesn't always mean cancer spread
Triple-negative breast cancers are a heterogeneous group and may not always be associated with lymph node spread, a new study shows. view more (2008-04-14)
Sun-damaged skin does not improve with estrogen treatments
Treating the skin with estrogen can stimulate collagen production-which improves the appearance of the skin-in areas not typically exposed to the sun, according to new research from the University of Michigan Health System. view more (2008-09-16)
Dartmouth researchers show effects of low dose arsenic on development
A team of Dartmouth Medical School (DMS) researchers has determined that low doses of arsenic disrupt the activity of a hormone critical in development. view more (2007-11-15)
Extracts of catfish caught in polluted waters cause breast cancer cells to multiply
Exposing estrogen-sensitive breast cancer cells to extracts of channel catfish caught in areas with heavy sewer and industrial waste causes the cells to multiply. view more (2007-11-07)
Stoned sea-squirts
The psychoactive ingredient of the drug cannabis exerts its effects on the human brain by activating proteins known as cannabinoid receptors. Dr. Maurice Elphick of Queen Mary, University of London has uncovered the first evidence that cannabinoid receptors may not be unique to humans and other vertebrates. The genome of the sea- squirt was... view more... (2004-03-31)
Growth hormone is made in the brain, report scientists
Scientists have found that growth hormone, a substance that is used for body growth, is produced in the brain, according to an article published in this week's Proceedings of the National Academy of Sciences. view more (2006-03-28)
How DDT metabolite disrupts breast cancer cells
Research has shown that the main metabolite of the insecticide DDT could be associated with aggressive breast cancer tumours, but there has been no explanation for this observation to date. Now a report published in the open access journal Breast Cancer Research shows how DDT could act to disrupt hormone-sensitive breast cancer cells. view more (2008-02-14)
Is that song sexy or just so-so?
Why is your mate's rendition of Marvin Gaye's "Let's Get it On" cute and sexy sometimes and so annoying at other times? A songbird study conducted by Emory University sheds new light on this question, showing that a change in hormone levels may alter the way we perceive social cues by altering a system of brain nuclei, common to all... view more...
