I have definitely noticed that breast pain that coincides with my period is worse since I have my diagnosis. The pain is also different in the breat that has flareups compared to the one without. I figured it's just another part of this that we have to deal with now.
I read your post and have started paying attention to see if there are flare ups during my period. I don't get my period since I had a procedure a couple of years ago, but I did notice that I was feeling crampy and had some spotting and that I had some pain in my breast, so I think you're right, it does have an impact. I also opted for holistic treatment instead of mtx and I feel positive about it. I hope we can stay in touch to compare how we are feeling.
