[|Human|] I have notice a small nodule or lump at the base of my hairline close to my left ear. It started very small in 2009 and the last month is enlarging and starting to protrude. It feels hard and hurts when I push down hard on it. I find it very anoying and I am worried it could be a lymp node with cancer. I get migraines and my estacine tube drains causing more sinus type migrain headaches. What should I do and what is this?
[|AI|]  Hi. Thanks for your query and an elucidated history. One thing is for sure. No lymph node in this position ever shown to be cancer. So first forget about cancer. It is not due to cancer. Let us see them what it can be. As you say this all started in 2009 - enlarging since last one month; this can be a sebaceous cyst or a lipoma or a lymph node too. You can test this by FNAC = fine needle aspiration cytology. And... It is better to get this removed (excised) for 2 reasons.1> your get rid of the disease and 2> you get the histopathological diagnosis-makes you tension-free that it is not a cancer. Well - another misconception- Eustachian tube blockage will cause problem of the ears only. Sinusitis can be a reason for this and the headache. The best way to get a proper diagnosis is consulted an ENT Surgeon who would do a proper history, clinical examination, investigations as per these findings alone can lead to a proper diagnosis. This is most important to lead to a proper management/ treatment.
