If you must pursue the course of alternative "natural" treatments, bear in mind that the cancer itself is "natural".

I suggest that you consider pursuing the conventional treatments at the same time as the natural alternatives as long as they don't interfere with each other (in which case I would personally let the conventional treatments take precedence) -- I know this is the tougher road to take, because the conventional treatments are very uncomfortable, but there it is -- One course has the numbers to back it up and the other goes on almost pure faith -- Ya pays yer money and ya takes yer choice!

Problem is, presuming you survive it all having taken the parallel courses is that you will spend your elder years (would that be your '30s? <g>) wondering which one worked, but some mystery in life is better than no life for sure!
