Hi Michelle,
Time for a little math class - just the thing to liven up a pity party.
According to your signature line, your original tumor was 2.5 cm x 2.1 cm x 2.4cm. The remainder is 9mm x 5mm x 3mm. First lets convert the remaining one to cms: 0.9 cm x 0.5 cm x 0.3 cm.
Although we all often talk about the length of a tumor, it is really the volume that matters. Your original tumor was 2.5 x 2.1 x 2.4 = 12.6 cc. Your remaining tumor is 0.9 x 0.5 x 0.3 = 0.135 cc. What that means is that you have 0.135 left, out of the original volume of 12.6. That is is to say, about 1% of the original volume (1.07% to be picky).
See, don't you feel better already? It actually is just a small percent of the original size. It would take only 1% of the radiation dose that the original would have needed. Lie on the table, get a little zap, no problem. And the facial nerve is pretty resistant to radiation.
Okay, it wasn't great news, the little thing could have had the courtesy to gracefully exit stage left, and it didn't. But it may not even grow, as surgery often disrupts the blood supply enough to prevent that. Even if it does grow, it is a small bit that can be taken care of if necessary.
I am sorry to hear it, but I hope you get back to focusing on that slow but steady recovery of facial function, and getting a TransEar, and all that stuff. Don't let this little bump get you down. Best wishes as always,
Steve
