Dressed to Kill (book)
Encyclopedia
Dressed to Kill is a book by Sydney Ross Singer and Soma Grismaijer that proposes a link between bra
s and breast cancer
. According to the authors, the restrictive nature of a brassiere inhibits the lymphatic system
. The book's claim that bras cause breast cancer has been dismissed by the medical and scientific communities; the National Cancer Institute
, the American Cancer Society
, and the National Institutes of Health
have all concluded that there is no link between bra use and 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 petrochemical
ly polluted food, air and water course throughout the body, including the breast tissue, and 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 claim that breast cancer is only a problem in cultures where women wear bras; in bra-free cultures, breast cancer is a rare event. In Dressed To Kill, 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 claim to have 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. Although they did not adhere to any scientific protocols for a medical study, the authors hoped that the medical industry would follow-up with further research to either verify or refute their findings. Their study findings were:
The authors published these claims in Dressed to Kill. The book generated controversy which the authors attributed the greed of the fashion and medical industries: "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.
". They are the founders and co-directors of the Institute for the Study of Culturogenic Disease (ISCD), located in Hawaii. Sydney Ross Singer received a bachelor's degree
in biology from the University of Utah
in 1979. He then enrolled in PhD training in biochemistry at Duke University
, and later transferred to the PhD program in anthropology, also at Duke University. Duke University gave him a master's degree
in anthropology
when he left the PhD program there. Singer later attended the University of Texas Medical Branch
at Galveston, where he entered but did not complete the MD/PhD program.

After self-publishing
Dressed to Kill, they 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. This last book also argues that physicians overlook these solutions at least in part because they do not earn any money from a healthy patient.
They founded the Institute for the Study of Culturogenic Disease in 1991. All of their books are self-published through ISCD Press.
They live in Hawaii
, on a 67 acres (271,139.6 m²) rainforest area that they have set up as a sanctuary for the invasive, non-native coqui
tree frog species. Their current focus is on the dangers of sleeping on a horizontal surface.
One specific critique of the their book by Martha Molete of the Cancer Association of South Africa argues that numerous aspects of the book's claims are scientifically unsubstantiated or unproven, citing:
None of the authors' surveys have attempted to account for any of the well-known epidemiological risk factors for breast cancer
, such as number of full-term pregnancies, age at first pregnancy, obesity, Western pattern diet
, or use of medication
s such as hormone replacement therapy
. Per Molete, "the authors' statistical treatment of their obtained data appears to be flawed. They do not include the data or a detailed description of the statistical treatment of the data. The two groups, i.e. those wearing bras and those that did not, were not controlled for many other factors influencing the risk of breast cancer."

Criticisms
Medical and scientific bodies which have examined the book's claims have generally dismissed them on the basis of poor methodology, lack of supporting evidence, and Singer and Grismaijer's failure to consider alternate explanations besides bra use for their findings.One specific critique of the their book by Martha Molete of the Cancer Association of South Africa argues that numerous aspects of the book's claims are scientifically unsubstantiated or unproven, citing:
- Lack of controlled epidemiological data correlating bra-wearing with the risk for breast cancer
- Lack of proof that the pressure exerted by a bra reduces the flow of lymph
- Lack of proof that lymph contains carcinogens
- Lack of proof that there are carcinogens in the human body that can induce breast cancer
- Existence of published data correlating obesity with post-menopausal breast cancer

database revealed no published scientific studies supporting a link between bra wearing and breast cancer risk. Furthermore, no scientific publications were found which were authored by Singer or Grismaijer.
Scientific counterhypothesis
The Molete article also discusses the one scientific study that examined the relationship between breast cancer and bra use. This study, among 3,918 cases and 11,712 controls from 7 centers in the United States, found that premenopausal women who do not wear bras had half the risk of breast cancer compared with bra users (P about 0.09). The authors offer the hypothesis that women who do not wear bras are thinner and likely to have smaller breasts. The same study found that among postmenopausal women only bra users with larger breasts had an increased risk of breast cancer (P about 0.026). The study suggests bra cup size is a proxy for greater weight and obesity which are known risk factors for breast cancer, and that the apparent risk associated with bra use is more likely a reflection of known risk factors for breast cancer, such as obesity.Opposing views
