Bras May Increase Risk of Breast Cancer

Biomed Middle EastWhile it may seem a bit far-fetched to speak of ladies’ undergarments being out to kill us, it makes perfect sense that brassieres could at the very least increase our risk of breast cancer. A few days ago, I ran across an interesting article on this very subject whilst updating myself on world news.

Most of the women with whom I work wear bras that are WAY too tight.  This constricts lymphatic flow, making it extremely difficult for the body to cleanse the area of toxins (including carcinogenic chemicals).  These toxins build up and form lumps, cysts – even cancerous cells and tumors.  From a lymphologist’s standpoint, anything that binds too tightly (especially in bands – like bra straps, bra bands, underwear elastics, tight belts, etc.) can be a serious obstruction to proper lymphatic flow.

The research cited goes on to say that locally increased temperature may alter hormone production, thereby increasing the risk of breast cancer.  Melatonin production also seems to decrease the more a woman wears a bra.  Melatonin has powerful antioxidant qualities and has been shown to decrease the rate of breast cancer growth.

Please take a few minutes to read the linked article.  More research needs to be done, but the numbers are nothing short of shocking.  Of the 4700+ women involved in the study:

  • Women who wore their bras 24 hours per day had a 3 out of 4 chance of developing breast cancer.
  • Women who wore bras more than 12 hour per day but not to bed had a 1 out of 7 risk.
  • Women who wore their bras less than 12 hours per day had a 1 out of 152 risk.
  • Women who wore bras rarely or never had a 1 out of 168 chance of getting breast cancer – The same as men who don’t wear bras!
  • The overall difference between 24 hour wearing and not at all was a 125-fold difference.
  • 80% of bra-wearers who experienced lumps, cysts and tenderness saw the symptoms vanish within a month of going braless.

Please take this into consideration.  If you are going to wear a bra (and most of us women will, nonetheless), it is important to take some precautions.  A well-fitting healthy bra should be slightly loose. . . .  You should easily be able to slip two fingers under the shoulder straps and under the band at the rib cage.  Also, be sure to massage your breasts after removing your bra.  This will help stimulate the lymphatics to do their job and take care of you!
