I am so confused

On Friday, I got a phone call from the hospital saying “your biopsy results are back and I can’t tell you what they are, but you need an urgent appointment with the oncologist Mr X so I will speak to him and phone you on Monday to confirm the appointment”. The way the person on the phone spoke made it very clear that the results were positive for cancer, just without actually saying the words.

I then got a phone call today from the hospital saying that they had spoken to Mr X (the Oncologist) and he said that my biopsy didn’t give a definite diagnosis after all, and that they have made an appointment for me next Tuesday (11th) to discuss things with Mr X. 

I am just so confused! How can the results be inconclusive? Surely they biospy either shows cancerous cells, or doesnt show them? I also have all the symptons and have been told that i am very very likely to have Cancer. SO annoying that i have to wait even longer.

-- also, they are testing for Hodgkins Lymphoma --

do you think it is more a case of 'we dont know if it is Hodgkins or non-Hodgkins' or 'we dont know if it is cancer or not'??

I feel like my emotions are really being messed with.
