benign?

3 weeks ago I found a small lump high up in my right breast, far up from the nipple. After panicking like crazy reading the referral notes from the nurse at the GP (hard non mobile) even though I can move it side to side.

I opted for a private appointment and ultrasound this week. The Dr said all looked benign and it was a lipoma or cyst At the nhs one stop clinic today,  I was told fibroadenoma in the ultrasound and had a biopsy which shocked me. The consultant didn't seem too concerned and said its due to me being 39 rather than anything suspect they've seen. Does this sound right for a fibroadenoma?
