We are all different but my own experience was having a negative mammogram. I was told over and over what the treatment would be i. e. Biopsy, surgery, radiation therapy. Of course I was in shock, so the repetition was helpful. I was given leaflets with more info, and a recommended forum for other support. The information scared me, as did the kind of conversations on the forum. I made some rules for myself. Only think about my own cancer. Only think about the next thing. Put my faith in the medical profession.
I had some strange experiences e.g. Radiation injection, 3 tattoos, to pinpoint the radiation, my surgery happened I came home on the same day with a handbag constructed out of a J cloth by the nurses to hold the container that the wound drained into. I had a bit of pain on Day 1 and got out of bed on day 2. I had a few tense days while waiting to see if cancer had reached the lymph glands. Good news. I recovered very quickly but was apprehensive about radiation therapy. 15 days of it. It was explained to me thoroughly and didn't take long. I experienced no skin problems and no fatigue.
The only pain I experienced throughout was the tattoo! I actually forget that I have had bc. To quote my sister "anyone would think you had a cold"
Sorry for the lengthy post, but I want women to know that we all fear the worst, but many of us will be lucky. Thank goodness for the mammogram programme.
I wish your daughter well. It must be so difficult for the mother. I was glad that my mother died before my bc.
