The study, published Wednesday in the International Journal of Cancer, followed 46,709 women, all part of the Sister Study, a National Institute of Environmental Health cohort of women whose sisters had been diagnosed with breast cancer. It found that, overall, women who said they used permanent hair dye in the year before enrolling in the study were 9% more likely to develop breast cancer when compared with women who did not. The risk was substantially higher among black women.

Definitively identifying causes of breast cancer might be limited by current science, said Dr. Otis Brawley, professor at the Johns Hopkins University Bloomberg School of Public Health and former chief medical officer of the American Cancer Society. Thousands of cancer diagnoses tied to a poor diet, study finds"Maybe these products cause cancer, maybe they don't," said Brawley, who was not involved with the study.

This is startling😖

'The study, published Wednesday in the International Journal of Cancer, followed 46,709 women, all part of the Sister Study, a National Institute of Environmental Health cohort of women WHOSE SISTERS HAD BEEN DIAGNOSED WITH BREAST CANCER.' That's a big part of this study, .

I figured that one out on my own. That there had to be a connection between hair dye and straightener and the people those that use them to breast and other cancers. That is why we have seen such a rise in it in this past years. Anything man made causes cancer.

This study is not new, hence why many black women stopped using hair relaxers. Or straighteners as you call it.

Is This?

What about the beautician who applys this stuff everyday.

Is that racist?lol woke fools

Natural and Organic is best. Long live Natural Afro Hair.

It’s only in women with sisters with breast cancer. And the absolute risk is TINY. What a misleading tweet. Smh.

Grey's a color and sexy

Well I’m fucked .

Women’s health. If it were vaping, where the effects were almost exclusively male, we’d never see hair color or bleach on the shelves again.

If you're going to slather your body in a chemical shitstorm expect some fallout later on down the line.

This is a racist research.

Yeah? Deo? Closer to breast.

RACE DOESNT MATTER! STOP BEING RACIST!

Well no shit.... c'mon

I do not believe this. At a certain time in life nearly all women will color their hair. I do not personally know anyone over 35 who has NOT colored their hair. So to say that is a causation is like saying using deodorant causes it....

Only in the state of California it is a risk for cancer.

Oh no no hiding the gray

Dying is permanent. It even says so on the bottle.
