Thanks everyone for your replies. KIris - Firstly - thank you for sharing your story. I hope that you are now fit and well. Yes I will be having the test done for the BRAC genes, but I think regardless of the outcome, it is something that I still want to do.

Lime - you make a good point about the mamograms, but it the whole going through chemo, and all the other vigors of ongoing tests etc, that I really do not want to do. My mum said that she strongly thought that she wanted a mastectomy when she was a similar age to me when she found a lump. The lump turned out fine, but no one took her seriously back then and she did end up with breast cancer.
My husband thinks that it is something that I should look in to, as he too was there through my mum and Aunt being so sick.
My mum has had a reconstruction, and to be honest, you can't even tell the difference, in fact her boobies look better than they did before!!!

I am at the start of this process, but I will seriously start looking in to it stating with genetic testing.
