My wife, 61, is suffering from ovarian cancer since 2009. After chemotherapy and surgery in 2009 ovaries with surrounding organs removed after which she was fine till 2012 when CA marker again started rising. After chemotherapy in 2012 she was again fine till 2014 when recurrence noted through CA level rising. Again chemotherapy in 2014 and CA level came down after three cycles. But 6 cycles could not completed due to sensitivity . After that we are following naturopathy with Budwig diet. Although she is fine clinicallynow with full energy, her CA marked has increased upto 300. She is diabetic but controlled after taking one tab of Glyciphage 500. Pl tell me what is relation between sugar level in the blood and CA level in the blood. Should we go for chemo again or continue naturopathy with Budwig diet?
