    Default Breast-Feeding May Protect At-Risk Women From Breast Cancer

    This is really significant research around family history of breast cancer and reducing the risk by breastfeeding.

    Very interesting article, thanks for posting. I've heard of other studies in the past that have tried to link the two together. I'm curious as to the science behind WHY they think that it reduces the risk, especially being someone that has been affected by breast cancer of 3 close relatives. Always the skeptical scientist, I also agree with this:

    Julia Smith, MD, the director of the Lynne Cohen High Risk Women's Clinic at New York University, says the study is “very interesting,” but not the final word on breast-feeding and breast cancer. “I think it's extremely hard to tease out this particular single variable, in that there are still confounding factors that weren't able to be isolated,” says Dr. Smith. “We can't be sure it's really the breast-feeding in that quantity that reduces the risk.
    There are so many other variables when they do these types of studies and it's almost impossible to isolate them. I always take more notice of experiments at the cellular level,where they can control the variables and focus on the cause.

    ETA: I'm NOT trying to downplay that this could be extremely positive news, just playing the devil's advocate!

    There have been many studies of this sort and they all show the same thing. Breastfeeding protects women against breast cancer:

    Breastfeeding and Reduced Risk of Breast Cancer in an Icelandic Cohort Study -- Tryggvadóttir et al. 154 (1): 37 -- American Journal of Epidemiology

    Review: breastfeeding is associated with reduced risk of breast cancer -- Bordeleau 8 (2): 63 -- Evidence-Based Medicine (this one isnt available in full unless you are a doctor, but findings were reported in this CNN article: CNN.com - Study: Breast-feeding lowers cancer risk - July 18, 2002 )

    Furberg H, Newman B, Moorman P, et al. Lactation and breast cancer risk. International Journal of Epidemiology. 1999; 28: 396-402.


    NEJM -- Lactation and a Reduced Risk of Premenopausal Breast Cancer

    Most impressive of all, a HUGE collection of resources compiled on the subject by La Leche League:

    LLLI | Selected Bibliography: Breastfeeding and Breast Cancer

    I am not sure why the original article posted implied this is new information, or questionable in any way. Breastfeeding has been shown again and again to be a protective of breast cancer.

    I have seen the previous studies; I was under the impression (mistakenly) that this was new research that backed up previous findings.

    Yeah, I've heard that for a while. I assumed new reseach backing up previous findings also.

    Sorry to hijack, DoulaMom. Since I have two primary relatives who had had breast cancer, (mother and sister)this is a subject near and dear to my heart. I really detest the way most medical folks that I come across, including ones who work in breast cancer screening, really downplay the protective ability of breastfeeding (especially long term breastfeeding) as though the research is absent or inconclusive. Which it is most emphatically not.

    A couple of reasons it is different then previous research is that it more clearly demonstrates the reduced risk for women who have a family history (not so much for the general population) and more importantly for this reason....


    Some research has suggested that breast-feeding protects against cancer, but those are typically studies in which breast cancer patients and healthy women are asked to recall their behavior years or even decades in the past, Dr. Stuebe notes. These types of studies can be flawed due to “recall bias”—meaning that they rely on people's sometimes faulty memory, she explains.
    In the current study, Dr. Stuebe and her team avoided recall bias by following 60,075 women in the Nurses' Health Study II over the course of nine years. In 1997, the women filled out a questionnaire about whether they had breast-fed each of their first four children, for how long, and whether they had used any lactation-suppressing medications. The researchers then followed them until 2005, during which time 608 were diagnosed with breast cancer.

    Oh and Hecate - no problem on the hijack. It is all on topic and I am not tied to my threads sticking to topic regardless.

    She means experiments in which cells or cell lines derived from patients with breast cancer, and similar cells and cell lines from normal controls, are treated with different compounds and the effect on cell growth or cell signaling are examined.
