biba70, I think you’ll find the underwired bra breast cancer link was discredited in 2014. A 2018 study trying to dispel myths said:
“Use of deodorant was the most common myth attributed to risk of breast cancer, while under-wired bras and perfumes/colognes were also incorrectly identified as having a causative effect.“
The theory now as I understand it is derived from larger scale studies. Researchers have discovered that it’s not is that underwired bras are responsible for an increase in cancer but that they are more likely to be worn by overweight women who tend to have larger breasts as well.
If you are not obese there is no difference in breast cancer rates between the underwired/no-wiring groups.
If you are obese, there is no difference in breast cancer rates between the underwired/no-wiring groups.
Obesity, on the other hand, is a big factor in breast cancer and risks are increased whatever bra you wear. Have a look on Google Scholar at the research papers.
I do understand that unwired bras are recommended after surgery. My own interest is that I have large breasts and am overweight. I wanted to know about underwired bras myself.
I do hope this is the end of the cancer for your daughter. You must have all been through a very worrying time. ?
