Biopsy and have just received another appointment

I had a mammogram and biopsy 2 weeks ago. The Dr said it was very probably a fibroadenoma, I'd get my biopsy results via my GP and I wouldn't need to be seen again until I'm 50 for regular screening. I've just seen on the NHS app that I've been booked a  appointment back in the Breast Clinic for February. Seems a bit strange. I will call tomorrow but just wondering if this is normal procedure.
