Brian, Thanks for the information and the article link. Since my husband's BOT cancer diagnosis in January, I've spent a great deal of time researching H&N cancer, treatments - traditional and complementary. Regarding the COX-2 inhibitor, are you familiar with an herbal product called Zyflamend -often recommended by Dr. Andrew Weil on his website, as a substitute for a prescription COX-2. A few of its key ingredients are turmeric (with turmerones and curcuminoids), ginger, and green tea, among others. I would be concerned about my husband using prescription COX-2 drugs since he has had liver problems in the past (although his liver tests have all been normal for six years now). Also, my husband is just 7 weeks post radiation. He never had to use the peg except to get extra water. He still has it. Would there be any issues with using the peg for green tea consumption? I'm most interested in anything that would prevent recurrence especially since he was just told there is a possibility he may have a tiny one in the exact spot that they did the surgery and then radiated. Tests are in progress. I, also, would love to see more on this topic.
