I just wanted to tell you a story about my partner. He is female-bodied, and suddenly had one side of his chest swell up and become very very painful. An ultrasound just showed an "abnormality". They couldn't tell us anything more than that until they had done a biopsy. Well, he went in for the biopsy and when he came out of surgery we were told that the abnormality was actually just an infection in a gland, that on an ultrasound came out to look like a 5x5 inch lump! They drained it and he was fine. Recovery took a while, but the relief that something that scary wasn't as bad as it seemed was huge! So, I know this is a hard place to be in, but sometimes it's easier not to expect the worst. I will cross my fingers for you.
