Hello, I had my 2WW appointment yesterday. I went with a lump in my right breast, but they also found one in my left breast. So I had an ultrasound on both breasts. They then decided they wanted to do a biopsy there and then on the left one. 

They said they look like Fibroadenomas which I did have one removed when I was 21. I’m now 36. But they said they wanted to do a biopsy just to make sure as one looked a little bit different. 

Are they ever wrong about these things? Has anyone been told they think it’s a Fibroadenoma and then the biopsy comes back different? They didn’t do one on the one in my right breast that I originally went with. 

Also it was only yesterday - I’ve taken my dressing off as suggested and the steristrips are still there for a few more days, but now looks like my breast is dented. Will this go back to normal?

Thank you. Feeling a bit anxious still.
