I found quite a large lump under my left armpit the other day. I have also found that one of my nipples keeps randomly inverting and my breasts are extremely tender. 
i had a doctors appointment yesterday and I was hoping that she was going to say it was just a large spot or a cyst but she didn't. 
She told me that she is referring me to a breast clinic but that they might not want to see me due to my age (22 nearly 23) and the fact that nobody on my mothers side has had breast cancer (that I'm aware of) does this seem right? She said if they don't want to see me then she will book me an ultra sound. 
 

I suffer with anxiety anyway but I'm super anxious now I can't help but keep checking whether the lump is still there and what my boobs look like. My fiancé is also really worried about it which I understand but it isn't really helping as it's stressing me out more. 
 

what should I expect to happen? Has anyone around my age been seen by a breast specialist before? I just want to know what's happening so I can try and put my mind at ease but I feel like I'm massively in the dark. Any advice or information welcomed
