Before following this treatment plan, I would suggest, as did the others, that you should seek out a second/third opinion at one of your cancer centers. I was recently diagnosed with a rare Stage -One high-risk micropapillary bladder cancer. And thanks to my second opinion at Memorial Sloan Kettering Cancer Center, NYC, I am now being treated by one of their former fellows. After 9 months of treatments and follow-ups, I am lucky to still be cancer-free. I am versed in the expertized of the international community in both cancer treatment and research, it is often much more advanced than that found in the United States. And I would like to add that your sister is much luckier than many Americans in that she does not have to worry about the costs of medical care.
