A report on a couple studies — one published in Chinese — suggests a strong link between bra wearing and breast cancer.
Other studies report a link between bra wearing and breast cysts and breast pain. The cancer link has not been medically established, but has not been scientifically disproven either.
The first and largest study that suggested such a link was by Sydney Singer and his wife Soma Grismaijer. They conducted a five-city survey of 4,500 women in the U.S. While that’s a large sample for a study, the work has been criticized as not meeting high medical research standards. The couple’s alarming findings are summarized on the website 007b.com as follows:
• 3 out of 4 women who wore their bras 24 hours per day developed breast cancer.
• 1 out of 7 women who wore bras more than 12 hour per day but not to bed developed breast cancer.
• 1 out of 152 women who wore their bras less than 12 hours per day got breast cancer.
• 1 out of 168 women who wore bras rarely or never acquired breast cancer.
That tallies to a 125-fold increase in the incidence of breast cancer among women who wore bras around the clock versus those who rarely or never wore bras.
The American Cancer Society dismisses the study and its conclusions as not being scientifically rigorous and says, “There is no other, credible research to validate this claim in any way.”
However, it appears that is not quite true. (more…)
