Worried about abnormal breast biopsy result

I went for a routine breast mammogram and received a letter asking to come back for further tests. At the callback appointment, they found cysts, which they drained, and took a biopsy.

Three weeks later, the biopsy results came back benign, but they wanted me to return for further investigations. I had another biopsy, this time of a larger area.

I’ve just received the results. One biopsy has come back benign, but the other has been reported as abnormal. The nurse explained that this doesn’t necessarily mean anything is wrong, but naturally I’m really worried.

I have severe health anxiety, and not knowing what the abnormal result means is really getting to me. Has anyone experienced something similar, where a biopsy came back abnormal but turned out not to be cancer?

I’d really appreciate hearing about other people’s experiences, especially if you’ve been through the UK breast screening callback process.
