I’m scared

A few months ago, an area that had a large cyst, supposedly simple cyst, has turned into something else. A very noticeable lump, semi hard, a little moveable, and this is just scary. I haven’t had a mammo in a few years bc I had nerve damage to my arm and couldn’t get myself up in there, so I was just doing my breast checks. I have an appt this week which I know is going to be an urgent ultrasound. I keep telling myself it’s probably okay; probably a fibroadenoma and that’s really what I want it to be. I hope (and pray) I can come back here with the good news all is okay.
