Turns out my mother has cancer again.Edit
I suppose I should offer more info
Turns out her cancer medicine has a side effect of causing more cancer. Go figure. A number of years back she had breast cancer; the doctors started out by saying then that it was just on one side and very minor. Turns out they were wrong, that it was on both sides and in her lymph nodes. The scale they go by is 1-4, 4 being terminal, and with her case she was a 3.5 (because apparently decimals are allowed) But after numerous infections and radiation and chemo, she eventually got over that. She went on a medication to stop it from coming back, although it has a side effect of causing cancer of the uterus, so she's had to go through regular tests for that.
And apparently all of the signs are coming back positive now. So she has to have a hysterectomy done in September, and we won't know until then how bad it is.
Anyway, thank you all for your comments, I hope this update will do in lieu of responding to them all
