We may never know whether bras cause cancer or not, but researchers are always trying to convince us that they know the answer one way or another.

And the cycle continues: a study, published this week in the journal Cancer Epidemology, Biomarkers & Prevention, promises bras aren’t serving up support with a side of deadly breast cancer. Cool, right? Only problem is that it’s in direct opposition to a study that came out about six months ago that claimed bras are in fact responsible for cancer cases.

What in the hell are we supposed to believe?

That research found that wearing a bra for 12 hours a day left women more likely to develop breast cancer than a woman who rarely or never wears one. The scientists behind it theorized that wearing a bra could trap lymphatic fluids in your breasts, preventing ‘em from moving around and releasing toxins. (What exactly are toxins, anyway? The study didn’t clarify.)

But the new intel, found by Seattle’s red Hutchinson Cancer Research Center, debunks that hypothesis. After researchers studied 469 post-menopausal women who hadn’t ever been diagnosed with breast cancer, comparing their habits to those of 1,000 women fighting breast cancer, they found no correlation between bra-wearing and breast cancer.

And remember: correlation isn’t even causation, so these researchers basically came to the conclusion that there is no freakin’ way bras could be giving you breast cancer.

One problem common to all these studies, regardless of outcome, is that it’s incredibly hard to find a control group — women who have never worn a bra are few and far between, and though ladies who don’t regularly get underwired are easier to find, they’re still not all that common.

Whatever the truth, one thing is totally clear: we’re spending a whoooole lotta time flip-flopping back and forth on this topic. And though prevention is invaluable, I’ll venture a guess that this time could also be spent on raising awareness and researching treatment options.
