I'm almost 2 years out from chemo and radiation treatment for tonsil cancer. It was first discovered by a swelling on my neck from a brachial cyst. They first removed that from the outside of my neck, then discovered cancer cells in it and removed my tonsil. There are now 2 smallish lumps along my surgery scar on the outside of my neck. I inly noticed them 3 weeks ago. My ENT says they're most likely scar tissue and don't touch them. I've asked for an ultrasound but he says no, just wait a few months to see. Should I wait?
