MRI RESULTS OVER PHONE

Hi,

I had a mri on 17th of April which was a follow up due to likely benign tumours found on last mri in December. I chased up my results after three weeks and have being told I am going to have a telephone consultation on the 18th may does it usually take this long for bad news? And would they tell you over the phone? Last time it was just a letter then a follow up phone call two months later to arrange follow up mri?
