What's the Prognosis? Dr. Who?

Filling out the form full of questions about my medical history, including "what is your ultrasound for", I hesitate.    I'm not completely sure what I'm there for.    Even going over the list of upcoming appointments I am a little unsure whether this ties into one of the other appt.'s or what!

Not long and I am just about finished filling out the questions and the Ultrasound Tech calls me in.    When she asks me my doctor's name I give her the name of my family doctor and she says, Oh, it's not Dr. F?  
"Oh, oh yes, from Peterborough.", I reply, "That's him, that's why I'm here!"!   We both laugh.   On the sheet I had written 'chest' where they ask what the ultrasound is for; another spot under observation. I followed "chest" with a question mark because I simply wasn't sure which follow-up this was!  This time last year I had gone under the knife for a benign tumour in my neck; Oct. 1st and this was THAT follow up before my next follow up appointment with the specialist!

Well now I know, July/August  and Oct. to Dec. I have enough Dr. visits to make ME question why I'm Here or there, when at other times I have felt certain the Dr.'s might be questioning my arrival, though they have assured me otherwise!
