Ok I know nothing about cancer but I follow this thread to check up on everyone I am praying for. So I have a suggestion on the smells thing. When pregnant the first time i could go almost no where because I was so ill from smells. I got rosemary oil since it was pleasing and did not make me gag and carried it everywhere. I spent a lot of time sniffing that scent. It is strong enough to cut through most other smells. Each pregnancy this has been a severe issue so I at times carried rosemary sprigs with me, fresh lavender, and even some fresh lemon peel. It was also useful to be able to rub some on my hands and meditate for a bit when I would get over anxious.
I also use something called unkers which is essentially for your muscles aches but it can be use for colds and such. Very strong, distinctive herbal smell. I find it super pleasant. When I have to go somewhere like the slaughter house to pick up the beef we just had processed I rub some under my nose. It has kept me from embarassing myself with my weak stomach. I really hope any of this might help you.
