Blood seen during ENT scope

Had appointment with the ENT doctor who scoped me and saw an inflamed area that had a spot of blood on it.  This was the same area as the tumor.  He asked me if I had been spitting up blood and I said I had not seen any blood.  I asked if it was just a spot that had not healed yet (only 11 weeks out of treatment) and he said he did not know.  He said he would do a biopsy as his next move.  I feel that this is going to be a problem and may be more cancer.  If the biopsy shows that I need surgery he said I could have it done locally with Dr. Saal or at Ochsner in New Orleans.

I see the Oncologist tomorrow and we will discuss the date for the PET scan.  Hoping to have it done the week of the 20th of this month which would be 3 months out from treatment.

This is not what I thought I would hear.  My throat has improved a great deal in the last few weeks.  Why is there blood in my throat?
