An Update
Well... we just got back from getting some test results. It is not the best news in the world... but it could have been a lot worse. At the beginning of the cancer return scare they saw 4 spots in my mother's chest that looked suspicious. Now I am glad to say they ruled 3 of the 4 spots are actually radiation scarring... but the one other is growing so is an active spot. At this point they are going with the idea that the cancer is back... but they can not confirm this until she has the biopsy. Which at this point they are still deciding the best method... whether they want to do the biopsy by going down her throat... or if they want to do it with a needle.
This one active spot is slowly progressing... so they feel like it isn't something they need to rush into... though they do want to get it done. At this point they are thinking if it is indeed cancerous they can get rid of it with a weaker form of chemo then she had to have the first time because it is progressing so slowly.
Right now they seem more concerned with finding out why she keeps becoming anemic. That seems to be a more pressing concern at the moment. They did say she is iron deficient... so that is part of it at least. We will know more in a couple days when we go back to the chemo doctor to check her levels.
