I've recently found a large, sore, lump on my jaw. It appeared just after having a tooth infection so I assumed it was related. Maybe a cyst or something. It had been a few weeks and wasn't getting smaller so I went to the doctors. He said it didn't feel like a cyst because it was very solid and didn't move. It felt more like a large growth from my jaw.
He then started asking about family history and cancer (there isn't any in my family). He ordered a FBC blood test and a glycated haemoglobin blood test. He said this would show any red flags and if it came back normal he would feel assured it wasn't anything serious.
My question is, I wasn't aware FBC showed much in terms of cancer detection (assuming this is what he thinks the 'red flags' might be) and why would he also order glycated haemoglobin which (I thought) checked for diabetes?
I'm a little confused
Any help would be greatly appreciated
