I wish I could answer definitively but Im Canadian - though I do get your love for CA I travel there annually its my vegan Mecca! I have heard people on the board say you can go directly to a cancer hospital but really just find out the number to the head and neck clinic and call. They can answer your question and likely book the appointment. Sometimes we walk around with blinders on. Because we don't really want to know or face something. There are times this is okay for a bit - but mostly and particularly with cancer it can be deadly. If nothing else the stress itself is unhealthy. If you do get a bad answer (a positive for cancer) the reality is you caught it and you can be treated. No one wants to face that, but once you know you can do something about it. But as long as you don't precious time is being wasted. Really, right now your in a state of paralysis, knowing will do one of two things - either let you act on it... Or let you get on with your life. It's terrifying, but you really do need to find out what is going on. Hugs!
