"Still waiting for biopsy results"

I was told in January that I probably had a malignant spot on my arm and it was removed rapidly, in February. I was then told that I would have the results of the biopsy in 4 weeks. It is now nearly two months since the surgery and I still have not received the results. I rang last week and was told I would get a letter this week. Not having received the letter, I rang again and there was no record of that call! Certainly no letter had been sent because apparently it was never written and the doctor is on holiday. Now I am waiting for a junior doctor to write and send a report. The suspense is agony.
