@ghadataher, I can imagine you and your daughter are very worried to have found a lump.
Here's more information from Mayo Clinic:
- Fibroadenoma https://www.mayoclinic.org/diseases-conditions/fibroadenoma/symptoms-causes/syc-20352752

Members like @trixie1313 @danielle0313 @cindylb @jane88c @smaac001 also have experience with fibroadenomas and can share their experiences.

I think you'll find this related discussion helpful:

@ghadataher, this is easy for me to say, but don't allow fear to paralyze you. If your daughter's doctor recommends further investigation and a biopsy, then you'll have more information and know what you are facing. Has a biopsy been scheduled?
