Core biopsy results

Hello all

I had a ct scan on my lungs which showed a lump in my breast.  Ive had a mammogram, ultrasound  and core biopsy. Was told i have a fibroadenoma and extra cysts and not to worry.

3 weeks later i now have a 2nd appointment and have been told this could last 3 hours etc but nothing about why.

I am guessing it could be anything from the biopsy went wrong , to cysts need draining,  to cancer.

Has anyone got some words of advice or wisdom re what to expdct and questions i must ensure i ask? Thanks
