Great - in that 9 out of 10 are benign should it be a cancerous lump.
Needle biopsy - be cautious - question them. Needle biopsy is a very very cheap way of getting a tissue sample. It often doesn't pick up enough of the right tisse for a meaningful test.
I had 2 done in my very enlarged lymphs - it doesn't show anything I was told. - That is not the same as YOU DON'T HAVE CANCER. What it meant was I was "monitored" for even longer while tumours grew larger in my neck lymphs. The only way is to have the lump (or part of it) surgically removed and have tests on it. Which I EVENTUALLY had. BASTARDS!
Sorry if I appear a bit negative - but the more I read about "needle biopsies" - the more I realise that they are extremely inconsistent.(ie a waste of time - useless)
Try and get a consultant to be really honest about this.
Good luck - chin up - keep positive
