Waiting for results

Hello, 

I had breast cancer almost four years ago and it was all going so well.  I'm 47 
In October I went to the gp with heavy periods , I presumed they would say I'm going through the menopause but they didn't. I was referred for an ultrasound where they found a tumour on my ovary. I've had an mri done which confirmed the tumour ( 3cm ) the mri was before Christmas and I'm still waiting for the official results. 
its really starting to stress me out. I phoned the hospital on Tuesday and they said the consultant would phone me back , I'm still waiting. 
Should I phone again?

I had a biopsy last week too. 
I've tried to stay rational and calm but it's driving me to distraction now. I've been ill over Christmas and am just getting over tonsillitis this week. I feel my body is letting me know something is wrong. Just feeling a bit desperate.
