Wait for biopsy resukts

I had a mammogram on November 14 - no symptoms but thought I would help with statistics as I am over 70. Recalled for further mammograms, ultrasound and biopsy on Dec. 6.  Told they only review biopsies on Tuesday’s and given oncologist appointment for Dec. 16.  This was cancelled late this afternoon as they did not have the biopsy results.  I asked if I could reschedule the appointment for Dec. 23 but was told they did not work like that.  I have been so worried and I feel the Breast Clinic was unsympathetic.  The tone was more I should be grateful that I had been spared a useless journey.  Has anyone else had a similar experience and do you think I will now have to wait until January?

Don’t think they will make you wait til Jan Anne but it’s not uncommon for results not to be back in time for scheduled appointments ,very frustrating and anxiety provoking having to wait longer when you are geared up to deal with the good or bad news.Have they not given you another date ?
