[|Human|] Hi, I ve had about 3 lumps behind my left ear - ranging in size from about 1mmX1mm to about 1cmX2cm - and my doctor keeps brushing them off. I have had them probably at least a 2 years now (yes, I told him this) but he insists it s, just the shape of my head . With my random bouts of dizziness and the fact they weren t there before, I doubt this. Please help! I m only 17 but I m very worried that it could be kidney cancer as I have a lump in my kidney as well (I know this because I had an ultrasound ), the hospital said they didn t know why I had blood in my urine, and I know lymph node cancer can stem from kidney cancer!!! :S
[|AI|]  Hello There. Welcome to Chat Doctor forum. It looks like you have a lymph node enlargement behind your ears... You need to get a detailed investigation including the removal of the nodes and pathophysiological examination of those nodes. This will help you to detect whether it is related any cancer or infection or its just physiological enlargement of the nodes. So consult a doctor and discuss with him about your case. Hope this helps. Take care.
