Actually there have been studies done that do link underwire bras to breast cancer. They DO NOT cause breast cancer but they can be a contributing factor. It is due to the fact that the underwire can often be very tight, thus reducing circulation to the breasts and hampering the drainage of lymphnodes (which carry toxins into the blood and away from the breasts).Therefore, while I would not say not to wear underwires (I do everyday!), it is important to gently massage your breasts underneath and around the sides upon removing your bra, just to aid in getting the circulation flowing properly.
gem> how about making sure your bra fits properly?
It isn't supposed to be tight. It's supposed to be snug, not cutting off circulation.
It takes approximately 20 mmHg of pressure to stop lymph flow. One will notice swelling, etc if that happens. Remember that many of the lymph nodes that circulate your breast are in your armpits and circulate DOWN to your breast, in fact not crossing your braline.
Here's a hint -- if your bra is pinching on the sides of your body and creating lines, try setting it a notch looser. No bra has to be that loose -- and if any bra is that tight, it doesn't matter if it's got an underwire or not -- it'll still cut off lymph flow.
I did a web search on breast cancer and underwire. Everyone has opinions. No one has facts. The prevailing opinion is that the idea of a relationship between underwire bras and cancer is far-fetched at best. As an intrepid investigator, however I did a search of the scientific literature through the National Library of Medicine. No study exists on the bra/cancer link. I did find two studies (retrospective) on breast SIZE and Cancer. The Results?......NO relationship when other factors are controlled for. So bottom line is..no one knows, but anyone who says there definitely is an increased risk is a liar and is itchin' for a fight.
Obviously a well-fitting bra will lessen your chance of reducing the circulation, but many women (especially those that are bigger in the breast and thus more likely to wear an underwire for support) do not have theirs bras fitted correctly...I was simply stating the reasoning behind the idea that underwires could contribute to breast cancer, although obviously these studies have not been proven conclusive.
oh sheesh...everything in this world causes cancer, and oddly enough, evrything prevents it at the same time...scientists are always changing their minds...so just wear whatever bra you feel is most comfortable, and chances are it will be no threat to your health.
