Remember that Seyfried mentioned that dissolving of tumors in his study depended on our blood glucose and ketone levels being kept above and below certain measures.
And don't neglect to consider your lymphatic systems circulation active or sluggish state.
And aaalso if you haven't pursued or discussed this but, body work/ chiro(preferable 'network' aka gentle sustained pressure chiro), you might find some extra help in the analysis of your head and spine alignment, the Boyd/Lemke bowling ball syndrome/adjustment which restarts or boosts the cranial sacral pump(spinal fluid) if stuck, which contributes to problems in body systems processing.
Scar tissue is a tougher matter than regular masses, tho I did post a link(somewhere) on the Dr from Kuwait who uses Dr Tennants protocol of Voltage with before and after X-Rays to successfully remove internal scarring.
Toxins are implicated secondarily in the autolysing process. They might interfere with our systems processing but not in the general principle of a masses being 'disolved'. A cysts not being affected by the state generated by a fast might be on account to it's location being not in contact with enough fluid circulation (blood or lymph) or hmm
The kidney styled lumps you and A mention may be so out of contact because of why they were generated (to isolate) and thus only a problem if interfering as a block or if the mass or the area becomes acidic and the cells start processing using fermentation rather then with oxygen.
