How long until I know?

Hi I’m in South Wales, had a biopsy in November and was told on Friday that the samples must go to a specialist lab and cancer panel in Cardiff to determine what type of lymphoma I have. The original lab could not make a determination. Anyone know how long this takes? The consultant was not prepared to state a timeframe. I’m a 55 year old man retired for 8 months and going out of mind with worry…
