Could Ditching Your Bra Reduce Your Risk of Breast Cancer?

Being the fiery (yet gentle) activist that I am, I’ve wanted to free a lot of things/people. The one thing I never expected I’d be fighting for, is freeing the boobies! Bras, or boob jail (as someone on my Instagram referred to them as) can do a lot more harm than good, I’ve learned recently.

We all know the feeling. You get home from work or a long day and you are just exhausted. You helplessly claw at the back of your shirt trying to unhook the bra that’s been digging into your shoulders all day. The moment the girls escape, a rush of freedom flows through your veins. FINALLY you feel at ease. But why can’t you feel like that all day? I always say that the closer we are to nature, the healthier we will be. What animal or primitive human in nature has worn a constricting boob corset all day? If it feels BETTER when we take off our bra… why don’t we listen to our instincts and get rid of it?

I know this sounds crazy at first because social constructs tell us we need to be “civilized” and lifted all day long. But today I found a reason to ditch my bra. There is evidence of a link between bras and breast cancer.

Sydney Ross Singer and Soma Grismaijer wrote the book above, called Dressed To Kill. They interviewed 4,000+ women in five major U.S. cities over two years. Half of the women had been diagnosed with breast cancer. Their findings were pretty interesting…

  • 75% of women who slept in their bras developed breast cancer
  • 1 in 7 who wore their bras 12+ hours per day developed breast cancer
  • 1 in 168 who did not wear a bra developed breast cancer
  • Within one month of ditching their bras, women with cysts, breast pain, or tenderness found their symptoms disappeared.

Ross Singer talks about her findings from “Dressed To Kill” in an article on


Bras, we discovered, are the leading cause of breast cancer. Like corsets, they constrict and interfere with circulation. Lymph fluid cannot easily drain from a bra-constricted breast. Backed-up fluid results in cysts and pain. This stagnant lymph fluid cannot be adequately flushed away, concentrating waste products and toxins in the slowly toxifying breasts. Ultimately, this can lead to cancer. Essentially, a bra-free woman has about the same incidence of breast cancer as a man. The tighter and longer a bra is worn, the higher the incidence. 24/7 bra wearers have over 100 times the incidence as a bra-free woman. These findings have been recently confirmed by studies in China and Venezuela. A 1991 Harvard study also found a significant bra/cancer link.

Andreas Mortiz, in his book, “Cancer Is Not a Disease – It’s a Survival Mechanism” revealed that Japanese, Fijians, and women from other cultures were found to have a significantly higher likelihood of developing breast cancer when they began wearing bras!

The 1991 Harvard study mentioned in the quote above reads: “Premenopausal women who do not wear bras had half the risk of breast cancer compared with bra users…” (CC Hsieh, D Trichopoulos (1991). Breast size, handedness and breast cancer risk. European Journal of Cancer and Clinical Oncology 27(2):131-135.).

In 2011 a study was published, in Spanish, also confirming that bras are contributing to breast disease and cancer. In the study, it is stated that underwire and push-up bras are the most harmful, but any bra that leaves red marks or indentations may cause disease.

It makes perfect sense. Bras are designed to alter breast shape, so they apply constant, unnatural pressure to the breast tissue which in turn constricts lymph vessels and flow. This is easily seen by the red marks mentioned above.

And guess what – wearing a bra has been shown to make your breasts sag as well! Many women are worried that by losing their bra, they will have no support and their breasts will lose firmness and lift. In fact, if you DON’T wear a bra, you make the muscles in your breasts work, meaning they will stay firmer for longer on their own. NATURE, baby!

What can you do?

I know that it’s not always possible to go bra-free. My best advice is to wear one ONLY if you HAVE to! Never, ever sleep with a bra on and if you do wear one for a business or professional setting, assure that it’s not a push-up, underwire, or tight bra. You can also wear a non-constricting layer under your clothing such as a camisole. Another great option is a very loose and dainty lace or organic cotton bra.

Oh my goodness! As I sit here munching on my daily carrot I come to this fantastic article!! I strongly support FREEING the Nipple!!! So it also means I started supporting freeing the breasts from jail as well. The moment I felt comfortable wearing no bra DAILY was about a couple years ago. I wear sports bras and very loose fitting bralettes if need be but all my friends know they can see my nipples on a daily basis. 😉 NO SHAME!! Love this. Thank you!


Love this! I’ve been bra-less for a while, but I was just wondering if you could recommend any brands or types of bras that would be better, if it was necessary to wear one? (For instance, like you mentioned, in a professional environment, etc…) Thanks!


I do love this idea and agree with it but having 36F boobs swinging about is not always comfy, bras with no underwires dont support and I get a rash from sweating to much, it hurts to excersise without a bra too and running is a no no, aghhhh what to do???


I can’t wrap my head around not wearing anything at all. When I wear a sports bra in public I feel so naked and exposed. Eww. That being said, I am open to the idea of an organic bra without underwires. Is there a brand you can recommend?
