Interesting.

Thank you for this!  My dad has metastatic melanoma in his lung and brain and is taking several immunotherapy drugs.  While the cancer is at bay thanks to these pills, his health is failing in many other ways now. I've finally convinced him to go see a holistic doctor to consider the impact that the drugs are having on his overall system and get some support for his body (aside from drinking Boost and this stuff for dry mouth that's full of parabens...argh!).  This article is a great bit of info that I can share with him.
