<s>[INST] Hello! I woke up this morning to find a lump on the tip of my neck under my chin (almost like and Adams apple) it seemed tender and a bit painful if touched or messed with. It almost seemed like I slept wrong. To give some info, I do smoke. But Im young 23yrs old and never had any severe illness. I sometimes would get tiny swollen glands on the side of my neck which would go away. So Im a little shocked to have woken up to a decent sized lump. Of course my main worry is cancer or tumor.. But it wouldnt pop up overnight ? So my question is what should I do? [/INST] Hello this is Chat Doctor. Thanks for the opportunity to help you.
