Dentist sez he can put the permanent cap on during radiation period if Dad feels well enough, or they can wait until he's done. He sees the RO for the final run through on Tuesday, so we can ask him about his thoughts on it then. He was fitted for the flouride trays Monday and should get them today. His RO said by week three things likely would get rough. It's the same RO who did rad on a non-Hodgkin's tumor on the head in 2001 and another on the back in 2003. Dad just finished chemo (w/Retuxan)in January for non-H tumor in stomach. He was supposed to get his next Retuxan-only treatment in June, but oncologist sez it can wait till he'd done w/ rad for oral. Wondering if all this prior treatment for non-H will make it more likely he'll have problems with rad for the oral cancer. Seems like the hits just keep on coming.
