Husband is a Hodgkin survivor - now has tonsil mass

Hello All...
I have been all over this internet, every day for 5 months now. My husband had Hodgkin's Lymphoma 10 years ago - found in Stage 3B. Tumors in his right lymphnodes and in his chest. He had a year of chemo/rad. 6 years ago he came home from travel with a lump on his neck. He was seen by his PCP who then referred him to the Oncologist and he was in surgery the next day. They said if we'd waited a week or so, he could have been full-blown again. A few years later, he develops a cyst behind his ear and we take him to the Oncologist (no insurance-paid cash), and he made an appointment to have it removed. Surprisingly, it disappeared. So here we are with yet another growth. This time it's on his tonsil. He told me about it on Mother's Day of this year. However, he tells me that he's had it for around 6 months. Yes, I know... why did he wait so long? Anyhow, I get him an appointment but they say his PCP is too booked to see him so they send him the nurse practitioner. I called and made sure they knew the seriousness of this matter with my husband's past. She looks at the mass and says, "oh yes, that needs to come out". But, gives him anti-biotics. She refers him to the ENT and he says the same thing. So he decides to do the surgery but says he needs to do a sleep study to obtain a breathing machine needed for after the surgery. My husband does that, and a breathing machine is approved by our insurance in August. After a few inquiry calls.... it never shows.

So here it is now 4 months after his initial ENT visit and he's barely having surgery in days. Almost a year with this growth cannot be good. I'm so scared. We are in our mid-thirties with 3 kids and not knowing is killing me. I don't know why I seem to be the only one worried. I've become expert on the possibilities of the actual diagnosis but am trying to keep some glimmer of hope alive. Anyone else gone through something like this..... Hodgkins, tonsil mass?? I can take it! Thanks for reading.
