No need to apologise - we have all been there with the waiting at some point or another and it’s awful. After my biopsy had confirmed that I had cancer I had a procedure under local anaesthetic to remove it . I wasn’t in pain but it obviously wasn’t going well , it took twice as long as it was supposed to and they took four times as much tissue as planned and at the end the Radiologist admitted that they thought they hadn’t got it. Then it was a long wait for a check mammogram due to having to wait for a haematoma to absorb then another wait to be told that they hadn’t got it - which I already knew . I was fairly ok up to the last two weeks which felt like torture. So I sympathise very much with how how you are feeling now and I hope that you are not too sore. It doesn’t sound as though you have been referred to the BCN service though at least you seem to have made a sympathetic contact . I suspect the reasons for wanting a biopsy before an MRI are logistical as well as clinical but I don’t want to give you inaccurate information - if you contact the Breast Care Nurses on the helpline and talk it through with them ( 0808 800 6000 9am to 4pm Monday to Friday and 9am to 1pm Saturday) they might be able to explain and give you a bit more support .
Sorry that you are in this situation and sending love . Xx
