回复：危难情况，求助指点！急急急！！！

Don't worry too much.
My sister had this one one year ago.
She had surgery. Doctor here had some special procedures to cut off the tissues around the cancer cells left with a big, deep hole (you can find info online). I think doctor in China know this too. I didn't hear any medicine doctor used.
Also she changed her diet, take one kind of herb tea (from a canada nurse's recipe, you can search on line) and detox her body too.
