You might have heard on social media that wired bras and sleeping in bras can cause breast cancer. Negative ideas are more compelling to the human mind. Let’s think twice and look at the evidence.
The source of this idea came from the book, Dressed to Kill, and internet rumors. The authors of the book believed the confining nature of bras constrained lymphatic circulation and would result in fluid build up in breast tissue. Many medical organizations like the National Institutes of Health (NIH) and the American Cancer Society noted there is no evidence that wearing bras increases the risk of breast cancer.
One study countered the book and Internet claims by inspecting over 1,500 postmenopausal women first diagnosed with invasive breast cancer. These women were asked a series of structured questions to find lifetime patterns of bra wearing before their breast cancer diagnosis. The researchers found no connection of invasive ductal carcinoma (IDC) or invasive lobular carcinoma (ILC) breast cancer with bra wearing such as bra cup size, recency, average number of hours in a day worn, underwire bras, and age at which bras were worn regularly.
Worrying is no fun. The next time you are taking a nap with your bra on, don’t stress about the risk of breast cancer!

Great to know, another curiousity is if can not wearing bras contribute to accelerate breast sagging, depending on the size and the relative progressive wear and tear of its sustaining ligaments caused both by prolonged unrestrained movement and the gravity pull which my act more on unsupported breasts? There have been a study which affirms it’s debunked and it’s a myth but apparently it’s limited in sample and age bracked, and only included young women up to the age of 35.
It’s an remarkable paragraph for all the online visitors;
they will take advantage from it I am sure.
