Dressed to Kill (book)

Background

Singer and Grismaijer argue that bra-wearing may be a major cause of breast cancer because of the purported effect of the bra on lymphatic circulation. Their interpretation is that constriction from tightly worn bras inhibits the proper functioning of the lymphatic system and leads to a buildup of fluid within the breast tissue. In addition, they state carcinogenic substances that we take into our bodies through petrochemically polluted food, air and water course throughout the body, including the breast tissue, need to be flushed from the tissues by the lymphatic system. Hence, bra-induced constriction of the breast lymphatic vessels, according to the authors, concentrates these toxins within the breast tissue, which may ultimately lead to cancer.

Singer and Grismaijer claim 70% of breast cancer cases are unexplainable by the then-current [as of 1995] known risk factors for breast cancer. In addition, the authors state that breast cancer is only a problem in cultures where women wear bras; in bra-free cultures, breast cancer is a rare event. They argue that women who wear a bra 24 hours a day are 125 times more likely to have breast cancer than women who are bra-free. Their study also claims that bra-free women have about the same incidence of breast cancer as men.

Singer and Grismaijer state that they noticed that the Māori of New Zealand, who are integrated into white culture and therefore wear bras, have the same rate of breast cancer, while the aboriginals of Australia, who are bra-free, have practically no breast cancer. The same was true for “Westernized” Japanese, Fijians and other bra-converted cultures.

Singer and Grismaijer examined the bra wearing attitudes and behaviors of over 4,700 US women in 5 major cities. They claim about half of the women questioned had had breast cancer. Women who had had breast cancer were asked about their bra-wearing habits prior to their diagnosis of cancer. The authors add that they hope that the medical community will follow-up with further research to evaluate their claims scientifically. The authors conclude: "The bra industry is a multi-billion dollar enterprise. And billions of dollars are spent each year researching and treating this disease. Ironically, ending breast cancer can cause financial hardship for many people." To dismiss critics of their work, they claim the mainstream medical organizations all denied the link between smoking and lung cancer for decades after the initial research was published.

After self-publishing Dressed to Kill, Singer and Grismaijer wrote another book about the dangers of wearing bras and several other books, in which they argue that sleeping on a tilted bed can prevent everything from Alzheimer's disease to impotence; that defecating, urinating and sweating more frequently and more copiously can prevent many conditions such as prostate enlargement and the symptoms associated with menopause; and, in The Doctor Is Out! Exposing the High Blood Pressure, Low Thyroid and Diabetes Scams, even that these three lifestyle changes can prevent high blood pressure, low thyroid conditions, and diabetes.

Scientific reception

Medical and scientific bodies have generally not supported the book's claims about bras and breast cancer:

The authors' proposal that bras block the lymphatic system which leads to accumulated toxins and cancer was likewise contradicted by scientific study. The National Institutes of Health examined cancer rates among women who had their underarm lymph nodes removed as part of melanoma treatment: "The surgery, which is known to block lymph drainage from breast tissue, did not detectably increase breast cancer rates, the study found, meaning that it is extremely unlikely that wearing a bra, which affects lymph flow minimally if at all, would do so."
