Breast lump - not worried. Am I normal?

hi everyone - I found a 2cm lump on my left breast 12 days ago. I am at the breast clinic on Tuesday. After the initial panic that lasted two days,  I've gone the completely opposite way and convinced myself it's a Fibroadenoma. I'm 44. The lump which felt fixed now feels a little mobile and I can grasp two sides of it. It doesn't hurt and it's just near my areola. I still want it removing even if it's a Fibroadenoma but I can't believe it's nothing other than benign. Those I've told however, are having melt downs about it whilst I'm extremely positive it's benign and Tuesday is a formaility for me. So much so, I've ordered everyone to stay away and I'm going alone. I think it's possibly because I know a lot about breasts being a lactation consultant and the statistics are very much on our side. It's helped me massively looking at the statistics and realising it's much more likely to be ok. I'm sad for those where it isn't though. I hope that doesn't make me strange! I'm finding those around me can't cope with my response and seem to want me to be worried and treating me like I'm ill! The only time I struggled was going straight to a lactation consult to help a mum after the GP referred me to the breast clinic. Good luck to all of you who are in this boat over the next few weeks xx (copied from my reply to another post)
