Hope all is going well with your sister. If your sister is willing to "do the things" - quit smoking, change her diet, keep an open mind and believe she can heal - I highly recommend Hope 4 Cancer in Tijuana Mexico. They also have a location in Cancun. My mom learned she had metastatic lung cancer (from smoking) and was not willing to do chemo (and we agreed it would have killed her faster), so after a lot of research, we found H4C. We took her there for a 3 weeks "boot camp" of treatments and learned a ton. Mom did the things while she was there and got stronger and her tumor markers reduced. She unfortunately was not willing (or emotionally able..?) to do the work when we got back. I do believe we got more time with her than we would have had otherwise. Wishing you well.
