If you’re a person with breasts, you probably know that a nice, supportive bra is kind of a necessary thing in life.
But you may have also heard some rumors that your bra is trying to kill you by upping your risk of breast cancer.
Before we go any further, let's get one thing out of the way: There is no scientific evidence to show that bras increase the risk of breast cancer.
So why is Goop saying your bras are giving you breast cancer?
Most of the claims that your bra is trying to kill you come from a 1995 book, Dressed To Kill: The Link Between Breast Cancer and Bras.
Here's the thing: The study in that book didn't actually factor in known breast cancer risk factors, like family history, weight, etc. It just found a correlation — not a cause-and-effect relationship — albeit a scary one.
There are a few other studies in the Goop article that Sadeghi claims show a link between breast cancer and bras. But those still don't give conclusive evidence that bras are out to get you.
That's a little like saying that ~Netflix and chill~ causes STIs.
So wait, why would your bra be giving you breast cancer anyway? BuzzFeed Life asked Weiss and Gunter to weigh in on each of the theories from Sadeghi's article:
The claim: Your bra "restricts the lymph nodes around the breast and underarm area, preventing toxins from being processed through them and flushed out of the body."
The claim: Bras with metal underwire have the "ability to magnify and sustain electromagnetic frequencies (EMF) and radiation from things like cell phones and Wi-Fi."
Weiss: "It's not like you would have a higher metal content or that you absorb the metal that's in the underwire."
Gunter: "If it's just metal, why aren't we worrying about zippers and penile cancer? Necklaces and thyroid cancer? If metal caused cancer, we wouldn't give hip replacements."
The claim: "Breasts are external organs meant to hang out and somewhat away from the torso, maintaining a naturally lower temperature than the rest of the body. Certain cancers are temperature-sensitive."
Here are the known factors that actually can affect your risk of breast cancer:
• Genetic mutations
• Family history of breast cancer
• Dense breast tissue
• Age at first menstruation and menopause
• Alcohol consumption
• Physical activity
• Birth control use
• Hormone therapy
