Some oncologists will consider reducing the dose temporarily if a person is having too many side effects.
Or an oncologist can delay treatment a week or so if a person is having too many side effects.
Most oncologists want people to hang in there and get as much chemo as possible, but if a person is having alot of side effects or getting depressed about all the side effects and is ready to give up they are willing to make adjustments to the treatment ocassionally.
Most oncologists can offer other kinds of help or prescribe things to conteract some of the more unpleasant side effects.
Your mom should be up front and discuss her concerns and problems with her oncologist openly. If she won't or can't do it try to accompany her to some of her appointments and express your concerns to her oncologist.
