Our oncologist states "4-5 weeks".
Background: In March 2016, my wife was diagnosed with stage 4 breast cancer, metastasized to her liver; and told she would be dead by the end of 2016 IF she sought no treatment. Two weeks later she had her next antigen 27.29 and CEA blood tests/ On 5/31/2016 those markers DECREASED by 71% and 90%. she feels and acts asymptomatically. She is on Xeloda and a large amount of cannabis extract (I'm in the medical cannabis business). Xeloda has bad side effects, and cannabis has none. I'm in an analytical 'argument' with her oncologist about whether it's the Xeloda and/or cannabis which has brought my wife such positive results. We would appreciate any feedback about how quickly Xeloda has been proven to start working. Thank you.
