keep in mind that the number of people who get breast cancer during their contraceptive-using years is quite low, so a 25-30% increase may not actually be very many people.

It’s interesting but I’m not sure some of it makes sense. Progesterone-eluting IUDs are supposed to result in much less progesterone systemically than something like Depo-Provera. It seems like every ten years or so there’s a seesaw that changes estrogen/progesterone from miracle drugs to poison and then back again. Sigh. “further research is needed.”

30% increase, which means 8 more people per 100,000 women who take hormonal bc. not 30% of people who take hormonal bc
