Taking turkey tail and in urine is whispy white cloud like material what could it be, tumor breaking up?

No: Tumor breaking up this rapidly would give you tumor lysis syndrome and render you very sick. I suspect the cloud is phosphate precipitate. In any case, i'd draw no conclusions. Turkey tail contains interesting chemicals but after several years and despite some too-good-to-be-true claims, nobody's got a thing that's solid. Good luck & stay hopeful and proactive.
