Hi,
I'm also battling liver cancer (reocurrence) (3 nods of sarcoma spread to the liver). My tumour markers are ok. Liver funtion so so, creatinine high. Just recently I said no to a third round of chemo and started my journey into alternatives. ... well, later I'll post my story..
But, coming to the point of the urine, the best bet is to contact Dr. Capistran in Mexico. He will make a vaccine called urine antigene made out of the urine you send him. I fairly inexpensive, and you apply it IV. (is very effective).
I may suggest to start rifing and papimi too.
