[Everything doTERRA] Xeloda (chemo pill) & EOs

I'm cutting & pasting again so I don't know if this will go through but my daughter-in-law's mother is still battling breast cancer & just recently been given Xeloda (my daughter-in-law thinks that's the name of it).  Pat (or others), when you talk about using the EOs aggressively in between treatments, what would you suggest w/this chemo pill?  She was stage 4 last January, went through aggressive chemo up until June, then had a PETSCAN July 1 that showed no hot spots but Nov 1 another scan showed the cancer was back.  She's had some pretty rough side affects w/this pill (she takes the chemo pill for 3 weeks then has 1 week off, I think)--lots of nausea, hand & mouth disease, etc.  I haven't known a ton of what I'm talking about w/doTERRA & cancer but have forwarded several posts from here to her & her daughters.  I have talked to her & her daughter about frank, cancer protocol & LLV.  She started rubbing frank on her feet in October.  I'd talked to her again the 1st of Nov about also taking a frank capsule a couple of times/day but I don't think she's started that.  Her thinking was to take the 1st round of pills for 3 weeks (which she has just completed), see how the results come back from being on the chemo pill for the 3 weeks, then maybe think about starting LLV & more frank.  She meets w/Huntsman Cancer Institute tomorrow & her daughter is going to take in the supplement box & the product info sheets.    Obviously I wanted her to start on all of this in January but . . . maybe soon.  Any of you, pls tell me what you think + is LLV or frank wasted if she's using those things WHILE she's taking the chemo pill?  I hope to sit down w/all of them tomorrow when they get back from the dr.  THANK YOU VERY MUCH for any testimonials/suggestions.
