What type of Cancer? Yup-sounds the same. I am so happy for you that you are on the last 2!!! What a triumph! Before my dad's break in treatment he was getting that awful mucus crap. What we did was get him a suction device (you know, what they have at the dentist.) That helps big time. I would imagine your mom would benefit too, since it will take a while for things to even out.
Did your mom have any breaks from treatment?
Ditto on the the hanging in there-I can't imagine anything worse than seeing a parent suffer. It just tears my heart apart. Nothing is put before you that you can't handle, I hang on to that.
Hugs to you.
