Molly,
Just my opinion, but you hopefully you can get your sister to a different doctor. Of all my docs the radiation oncologist was my favorite, but he also never did anything on a follow-up but look down my throat and ask me how I was. And say yep, he burned that tonsil up.
I don't know that he's supposed to do any different. My ENT and Rad guy were on alternate months for follow-up. I wasn't comforatble with someone just looking down my throat (thanksto this board) and switched to an ENT Oncologist, who immediately sent me for blood tests and ct scans. No one ever did an after rad & surgery ct scan. So no baseline,until he sent me.
I'm not sure how long he would have waited for another series of scans. I didn't get to find out, because while all these docs were making really good money off a 10 minute appointment to LOOK down my throat, I was growing tumors on my liver.
No one ever did an abdomen or pelvis scan on me to see if my SCC had spread. Angry, yes I get angry, if it hadn't been for Brian and this board, I might not have gone to the doctor when I did. And I have Stage 4/metstastc liver cancer.
Julie has the right things happening and hopefully with my new team of oncologists I'll be in good hands in the future. (by the way, none of my cancers have shown in the blood-not even the liver cancer)
Take care,
Dinah
