usage of flax seed oil and xeloda in breast ca with mets to bone - 1249305

Hi, I am new to the grace website and I just wanted to say that the readings that I have done so far have been quite helpful and encouraging as well. Thank you for your sacrifice of time and energy :). I am a 54 y.o. woman, dxed with Lt breast ca in 2003 had lt lumpectomy,1 lymph node pos; adramycin,cytoxan q3wks x4 and then taxol, followed by 6 wks of radiation.I was cancer free until 1/12 when I was dxed with breast ca again in Lt breast with mets to bone(spine).fx's in spine with txed with 2wks radiation & had 5 cycles of abraxine and exgeva with great response to tx. I was on faslodex for about 21/2 mths and noted regrowth in my breast.(confirmed with pet scan and mri of breast, bone remains stable) I Just started xeloda 1500mg bid 1 wk on 1 wk off. I would like to use flax seed oil from time to time when I feel respiratory congestion coming on. I like to use it first before going to antibiotics(I always let my oncologist know if symptoms persist). In the past I would use it for a week or so and it generally worked to stave off any progression of congestion etc. I was wondering if flax seed oil would interfere with my chemo.
Thanks for any insight that you can give.
