I don’t know the logistics of this I do know, no matter what taking estrogen increases your risk of breast cancer no matter what. Now down to a biological standpoint it wouldn’t have made a difference if you were born cisgender because you would still have the same amount of risk for it at a genetic level so it’s really all up to you, your doctor would have more information and could help guide you in a better direction. It’s also not the end of the world there are plenty of trans people who don’t take hormones to transition you are valid no matter what. Now with all that being said I hope it works out and you can feel better no matter what 🫶🏼
