I completely understand your fear, I had an ultrasound becausei found a lump but the ultrasound showed 2 actual lumps attached to each other in the shape of an 8, one was 25mm and one was 19mm. They took a biopsy and I was supposed to go back yesterday for the results. On friday I had a call to say I need a further biopsy which I'm having tomorrow. They wouldn't tell me over the phone what the original biopsies showed, and I have no idea what it means to need further biopsies. The waiting is the worst part and the not knowing. I've has to distract myself by decorating the bathroom or I'd go mad thinking about it. I was abit like you, didnt take anything in and had so many questions that I forgot to ask. 

I hope your results come back quickly and everything is ok for you xx

Thank you , fingers crossed for you also , did they give you a score after scans? 

They may need another sample because original was not an good enough sample , I was warned that sometimes can happen 

No they never mentioned anything about a score, I asked them why I had to have another biopsy and what the results of the 1st biopsy were but she said shes not allowed to discuss it over the phone and that my consultant would explain all tomorrow, I'm trying to stay positive but it's hard. Just want tomorrow out the way so I can hopefully relax.
