6 weeks ago a large lump appeared spontaneously in my neck, after a week I called my GP who diagnosed either a cyst or swollen gland through a telephone consultation... 3 weeks later it was still there so contacted GP again who seen me, she was unsure of what it was but ruled out what previous GP has said. She put an urgent referral to ENT , had that appointment today and consultant has said it could be Lymphoma or brachial cyst  he inserted a neee into the lump to see if fluid came out which would make him think it was a cyst... no fluid only blood he said he is sending me for a scan and should get an app within 2 week ... any advice welcome
