Hi Sherri,
I am sorry to hear of this terrible news for you and your husband. I want to share that I had a similar experience 2 years ago. I was told I had cancer, they removed the lower lobe of my left lung and then discovered it was a blasto. I was lucky to be completely cured with Itraconozole. since that I have been pitching my story to law firms to attempt to sue for the unnecessary lung removal. A lung biopsy would have revealed it. Or a PET scan. Or sputam test, but none of these were done and I was told it was imperative to have the surgery asap. Now I have nerve damage from the surgery itself, which has caused a whole new set of problems.
Know that it is possible for your husband to be cured, with the right meds. It seems that his case is somewhat worse than mine, so I imagine he is on amphotericin instead if itraconozole. If he can tolerate the meds, I believe he will come out all right.
Can his employer let him go just because he was sick? Is there any chance of fighting that?
also, I went through all of the worry about whether or not I could have caught this from a moldy basement, etc. My research, and the doctor's answers, have been "no". This fungus resides insoil, in decaying vegetation. He didn't get it from a moldy environment. Any you can't catch it from him, either.
I wish you well.
