The Author's Dad was diagnosed with kidney cancer in Jan 2012 at the age of 89. Surgery, chemo and radiation were ruled out because of the age. This book is the story of how an at home test of urine pH and efforts to alkalize the body using calcium and vitamin D3 helped his Dad to remain healthy without any side effects of cancer, 2 1/2 years after the initial diagnosis. Chapter 9 covers many scientific data validating the urine pH test. Appendix B of the book outline the protocol followed for his Dad.
