Most often what you feel is right turns out to be the best decision. I straight out wanted the left mastectomy and my surgeon sort of raised his eyebrows and asked me to think about it for a week. After a week my answer was still the same. As it turned out I was right and as discoveries were found of a fatty lump on the other side of the breast and positive cancerous sentinel node, I would have had to probably have the mastectomy anyway.
I only have a small breast left and I have found if I wear a shirt with front pockets, it sits out in such a way I don't need any bra padding. In fact I never wear a bra at all any more. People mustn't notice either as many times with other doctors and optometrists sitting face to face I have had to tell them I am missing one boob.
