Trigger Warning: mention of abuse

Hi, I'm 22 and female. I had a GP appointment 2 months ago because I noticed one breast was suddenly bigger than the other. The GP found a lump and told me it's likely to be a fibroadenoma as it moves easily under the skin which is reassuring. She also said she wouldn't expect me to have cancer at my age but said not to think that just because I'm young, I can't have it and I should always get breast changes checked. I think that was really good advice.

It's grown more so I contacted my GP practice this morning. They booked me an appointment for this afternoon but unfortunately, I couldn't make it. The next appointment that's available is in 2 weeks so I've booked that.

I don't know if I should mention this but when I was 13-15, breast flattening with heat happened. Could this mean I'm at more risk of having problems? I'm worried I won't feel comfortable mentioning this to that GP and there's another GP at that practice who speaks more gently so I'd rather talk to her.
