But I'm just wondering if anyone else out there (besides me) *has* suddenly developed endometriosis since going on the cup? Not saying that they are definitely linked, but...what I was originally diagnosed with as just an ovarian cyst now appears according to my doctor to be endo (though I still need to go finish testing & probably a lap to make sure it's not ovarian cancer). I started using a cup about 2 years ago, and *never* had any gyno problems until now.
So, yes, it could be a complete coincidence or just something catching up with me as I get older. But it does give me reason to be concerned, especially as I find these articles potentially linking the two which I had never seen before.
(And yes, I know that endo has existed since long before cups came along. So has cancer, for many centuries/millenia, but that doesn't disprove the fact that modern day chemicals/factors can increase incidence of the disease.)
