    It is not just wired bras that have been linked with breast cancer - it is all bras.

    http://www.brafree.org/

    The link shows studies that show the link:

    STUDIES THAT SUPPORT THE BRA/CANCER LINK:

    1. 1991 Harvard study (CC Hsieh, D Trichopoulos (1991). Breast size, handedness and breast cancer risk. European Journal of Cancer and Clinical Oncology 27(2):131-135.). This study found that, "Premenopausal women who do not wear bras had half the risk of breast cancer compared with bra users..."
    2. 1991-93 U.S. Bra and Breast Cancer Study by Singer and Grismaijer, published in Dressed To Kill: The Link Between Breast Cancer and Bras (Avery/Penguin Putnam, 1995; ISCD Press, 2005). Found that bra-free women have about the same incidence of breast cancer as men. 24/7 bra wearing increases incidence over 100 times that of a bra-free woman.
    3. Singer and Grismaijer did a follow-up study in Fiji, published in Get It Off! (ISCD Press, 2000). Found 24 case histories of breast cancer in a culture where half the women are bra-free. The women getting breast cancer were all wearing bras. Given women with the same genetics and diet and living in the same village, the ones getting breast disease were the ones wearing bras for work.
    4. A 2009 Chinese study (Zhang AQ, Xia JH, Wang Q, Li WP, Xu J, Chen ZY, Yang JM (2009). [Risk factors of breast cancer in women in Guangdong and the countermeasures]. In Chinese. Nan Fang Yi Ke Da Xue Xue Bao. 2009 Jul;29(7):1451-3.) found that NOT sleeping in a bra was protective against breast cancer, lowering the risk 60%.
    5. 2011 a study was published, in Spanish, confirming that bras are causing breast disease and cancer. http://www.portalesmedicos.com/publ...ientes-que-acuden-a-la-consulta-de-mastologia - It found that underwired and push-up bras are the most harmful, but any bra that leaves red marks or indentations may cause disease.
    Studies that refute the link - NONE.

    If you want the truth of anything, follow the money. Who gets to gain from cancer? I only wear them when I am going somewhere - not shopping. I am not willing to take any risks with my already fragile health condition.

    I found the abstract of the first study here. It says (my bolding):
    The second and third links don't seem to be scientific studies.

    The fourth citation has an abstract here, which says:
    but sleeping in a bra is likely to be associated with larger breast size.

    The fifth link has Spanish text and a funny English translation, and does say:
    But they concede that it was a "descriptive, non-experimental, transactional (?) study." Admittedly, it would be hard, and probably unethical, to do an experimental study, but a prospective one would be more informative.

    It's a myth.

    It is entriely logical to me that any resriction will slow down lympatic drainage from the breast area. It makes no sense to claim that it doesn't.

    How do bra manufacturers gain from women getting cancer?

    It is illogical to believe something that has been shown to be nonsense.

    It's got nothing to do with the manufactureers. The bad information is coming from the cancer industry. Your links are unimpressive. They say that there has been one study which is a downright lie.

    I found the research linking dog ownership to breast cancer very interesting.

    A study found that reast cancer patients were twice as likely to own a dog, compared to healthy controls. This suggests that there is some factor connected to dogs that promotes breast cancer.

    One such possible factor is the mouse mammary tumor virus (MMTV), a retrovirus which has been shown capable of infecting human cells, and which triggers breast cancer in mice (although the tumors caused by MMTV in mice are benign and do not usually metastasize).

    Dogs may provide a route of transmission for MMTV, passing this virus to humans.

    @brenda -- if you want to post unsubstantiated information on a website for ME -- go right ahead. But when you post obviously biased information with absolutely no basis in reality, the information should be countered with information that is based in reality. How do you know the links I posted are unimpressive since I just posted them and you couldn't possible have read any of them in that amount of time. :eek:

    What cancer industry? It's ridiculous for you to even say that. I don't suppose you can see beyond your own biases because you have consistently posted claims of things causing cancer and when members try to give you information that might counter your beliefs, you don't read the information and keep saying the same things over.

    Weighing the information, it just doesn't make sense that a wire bra could even cut down lymph flow to any significant degree. And if it did, where is the link to cancer anyways.

    When it comes to cancer, there are known risks.

    Following the money.:confused: Are these people making spurious claims in a book not in it for the money? Puleez. Bras are not and never will be a cause of cancer.

    I wonder if there is a similar link with pets in MECFS...

    My mother was never near a dog in her life and she got breast cancer. I'm sure it had more to do with her eastern european genes among other things.

    @Kina , thanks for the research disproving this. What a crock.

    That does not really mean much statistically as a single N = 1 bit of data. Also, note that nobody is suggesting that MMTV might be the only cause of breast cancer.


    In 1971 a beta-retrovirus similar to MMTV was found in the milk from 5% of American women with no familial history of breast cancer, but 60% of American women with familial breast cancer.


    There is also a close relative to MMTV involved, which is human mammary tumor virus (HMTV). Genetically HMTV is very similar to MMTV.

    HMTV is found in 40% of the breast cancers studied in American women, but is not detectable in non-tumor mammary tissue from the same breast that contained the tumor.

    I notice that the author of the One More Time...No, Wearing a Bra Does not .... Adds to his list of things that are debunked, detox. Now I know that if I'd not spent as much time engaged in detox protocols during the past year, there's no way I'd be reading and responding to this thread. And he seems to challenge the idea of toxins in the breast. I saw a doco last year about just how many toxins do accumulate in breast tissue. It's now on a pay-to-view mode, a nursing mum tested her breast milk. Pretty scary!!

    I certainly hope any further studies include bras using whales!

    Are the posts linking dog ownership to breast cancer a joke or serious?

    "They" were also linking breast cancer to aluminum in antiperspirants at one time.

    It's serious, although the 2006 study was small (69 patients in Bavaria). They found that dog, but not cat, ownership was linked to breast cancer. I have not come across any replication studies, though, or anyone examining this further, so I wouldn't worry too much about it.

    There is also some criticism here about the study's methodology:

    The possibility that aluminum from antiperspirants might be a factor in breast cancer is still being investigated, as is the connection between breast cancer and parabens, which is another common ingredient of antiperspirants.

    It's because cat owners are slatterns who don't wear bras or antiperspirant.
