It may have been because I was an older woman, but I didn’t reflect too much on a ‘missing bit’. An arm or a leg would have been hard for all sorts of practical reasons not only body image. I remember being grateful that I was not one of those dealing with a tumour in the brain. I certainly didn’t like losing my breast, I didn’t hate it (I don’t see cancer as a personal attack) but I did accept the medical advice about the best treatment. My partner wasn’t remotely concerned, and slowly, neither was I. Embrace the change, it is what it is and treating your body (whatever shape) with love and respect is important. Best wishes.
