Ive had a bump where my neck meets my shoulder for a few years now and it seems to have grown a little recently and become a little tender.  I tried to make sure it wasnt just a big pimple and squeezed it.  White, bad smelling pus came out.  Could this be a sign of cancer?  Im kind of scared.
Welcome to Chat Doctor .1. No it doesn't look like a cancer, the way you have explained it looks like an infective thing with pus (could be carbuncle/fur uncle/abscess)2.If this case I would first examine and if its infective thing with pus - initially I will give you a course of antibiotics - if not resolved think for surgical removal.3. Before the procedure, I would ask for an ultrasound scan to see the constancy of the lump (solid/cystic/mass) and involvement of the adjacent anatomical structures (vessels/Bones/Muscles)4. Then plan further. So take appointment and get it treated before it gets complicated. Anything to ask ? Do not hesitate. Thank you.
