Study links breast cancer risk to epigenetic changes related to race, smoking and birth size

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.

2. Study finds no link between working the night shift and an increased risk of cancer
   08-22-2007 · EurekAlert!
   Working the night shift doesn't appear to increase the risk of developing cancer, suggests the findings of a new study of Swedish workers. Recent studies -- and corresponding news headlines -- have found that regularly working the night shift may increase the risk of developing breast, prostate and colon cancers.

3. Fetal cell 'transplant' could be a hidden link between childbirth and reduced risk of breast cancer
   10-02-2007 · EurekAlert!
   Some benefits of motherhood are intangible, but one has been validated through biostatistical research: women who bear children have a reduced risk of developing breast cancer. In Seattle, researchers at the University of Washington and Fred Hutchinson Cancer Research Center believe they have identified a source of this protective effect: fetal cells "transplanted" to the mother before birth.

4. 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.

7. Hip size of mothers linked to breast cancer in daughters
   10-08-2007 · EurekAlert!
   In a study of the maternity records of more than 6,000 women, David J.P. Barker, M.D., Ph.D., and Kent Thornburg, Ph.D., of Oregon Health & Science University discovered a strong correlation between the size and shape of a woman's hips and her daughter's risk of breast cancer. Wide, round hips, the researchers postulated, represent markers of high sex hormone concentrations in the mother, which increase her daughter's vulnerability to breast cancer.

10. Breast cancer and hormone therapy -- A looking-glass mirror?
    07-24-2007 · EurekAlert!
    A new study raises the issue of a direct link between breast cancer incidence and use of postmenopausal hormone therapy (HT). Breast cancer incidence and mammography screening rates during 1980-2006 showed similar but not synchronous periodic fluctuations. The implication that HT use equates to the risk of breast cancer is therefore too simplistic and inappropriate.
