Wearing a bra does not increase the risk of breast cancer, according to new research contrary to previous theory that claims an association between breast cancer and bra wearing patterns
Also a 2005 book entitled 'Dressed To Kill: The Link Between Breast Cancer And Bras' struck fear into the hearts of bra wearers and lingerie manufacturers.
It supported the idea bras cause poisons to accumulate in breast tissue.
That prompted a team from the University of Washington to study 1,513 women in the area, aged between 55 to 74.
No evidence of a link between breast cancer risk and bra size, type, or frequency of wearing, was found, researchers said.
Doctoral student Lu Chen, who led the research, said: 'There have been some concerns one of the reasons why breast cancer may be more common in developed countries compared with developing countries is differences in bra wearing patterns.
'Given how common bra wearing is, we thought this was an important question to address.
'Our study found no evidence wearing a bra increases a woman’s risk for breast cancer.
'The risk was similar no matter how many hours per day women wore a bra, whether they wore a bra with an underwire, or at what age they first began wearing a bra.'
#The research was published in the journal of Cancer, Epidemiology, Biomarkers and Prevention.
