Thank you for your additional comment. That helped a lot. I'm not sure if my sister is naive about the cancer or what. I am still trying, very hard, to understand. She says she has a "gut feeling" that it is gone and nothing more needs to be done. She thinks she should feel sick if it is still there. Regardless, her Dr ordered a PET scan next week because she is refusing any other treatment. So, I guess we will go from there.
