Dense breasts, hormone levels are 2 separate, independent risk factors for breast cancer

08-20-2007 · EurekAlert!

The density of a woman's breast tissue and her level of sex hormones are two strong and independent risk factors for breast cancer, according to a team of researchers from Harvard and Georgetown universities. The finding dispels the common belief that the risk associated with dense breasts merely reflects the same risk associated with high levels of circulating sex hormones, they say.

    07-12-2007 · EurekAlert!
    Estrogen, which binds estrogen receptor alpha (ER-alpha), is a risk factor for breast cancer development. However, one-third of new breast cancers lack detectable ER-alpha. These ER-alpha-negative cancers are more aggressive and have a worse prognosis than do ER-alpha-positive breast cancers, and have been thought to be estrogen independent. In a new JCI study, University of Miami researchers shed further light on the mechanisms regulating ER-alpha expression levels during breast cancer.

    According to the results of a study published in Gastroenterology, patients with high levels of insulin and glucose are at increased risk of developing recurrent colorectal adenomas, or tumors, with elevated glucose providing the strongest risk factor for recurrence of these lesions.

  3. Reducing cardiovascular disease risk factors when discontinuing hormone replacement therapy
    05-15-2007 · EurekAlert!
    Hormone replacement therapy (HRT) can reduce many cardiovascular disease (CVD) risks, but many women have stopped using HRT due to reports that HRT may increase the risk of breast cancer and heart disease. In a study published in the June issue of the American Journal of Preventive Medicine, researchers from the University of Pittsburgh Graduate School of Public Health examined whether the increased CVD risk from stopping HRT could be minimized by lifestyle change intervention.

  4. Discovery suggests location of genes for breast density, a strong risk factor for breast cancer
    08-31-2007 · EurekAlert!
    Studying the DNA of 889 people, gene hunters at the Mayo Clinic and H. Lee Moffitt Cancer Centers have identified a region on chromosome 5p that is significantly associated with dense breast tissue, a known risk factor for breast cancer. The findings are published in the September 1 issue of Cancer Research, a publication of the American Association for Cancer Research.

  5. Tumors stopped from spreading to new sites
    04-05-2007 · EurekAlert!
    For several types of cancer, persistently high levels of the soluble factor TGF-beta in the blood after surgery, chemotherapy, or radiation therapy correlate with increased risk of early metastasis and a poor prognosis. Using a mouse model of breast cancer, researchers from Vanderbilt University have now generated evidence to suggest that treatment with TGF-beta inhibitors might help such patients.

    05-27-2007 · EurekAlert!
    The most powerful genetic analysis of the DNA codes of over 40,000 women has uncovered five common genetic variants that increase an individual's risk for breast cancer.The five genetic variants occur more frequently among women with breast cancer than do BRCA and the other previously identified breast cancer susceptibility genes.

  7. Study links breast cancer risk to epigenetic changes related to race, smoking and birth size
    04-15-2007 · EurekAlert!
    Women can encounter environmental factors that increase their risk of breast cancer at various periods of their physical development, beginning before birth and extending until menopause. These non-inherited, or epigenetic, changes in DNA can correlate with risk factors for breast cancer, according to research being presented at the 2007 Annual Meeting of the American Association for Cancer Research.

  8. Younger African-American women at significantly higher risk for breast cancer
    11-07-2006 · EurekAlert!
    Despite recent overall declines in invasive breast cancer in the United States, African-American women, particularly younger ones, have not seen a significant decline in their rates. These findings, which are being presented at the American Pubic Health Association (AHPA) Annual Meeting in Boston, November 4-8, suggest the need for research to understand why these differences persist and to determine whether avoidable or preventable factors account for these patterns.
