Got a call to go in for biopsy results - bad news?

Hi 

I had a breast lump that they did a biopsy on and been in the dreaded 2 week wait . 
they rang me earlier saying results are back and booked me an appointment for Wednesday to discuss . 
I’m now feeling that this means it’s bad news if there calling me in for an appointment to discuss this soon ?

I was wondering if they always call people back in for good and bad news or if they say over the phone if they are all good.
