Suzanne - sorry to hear about your sister. Don't know how open either of you are to complementary therapies but I have a friend with a squamous cell cancer in his mouth that just returned from the Cell Specific Cancer Treatment Clinic. They have recently completed a clinical study and had great success with several different types of cancers most of which were in stage three and four. You can visit their web site at www.csct.com. Should you elect to call them - please feel free to use my name as referring you as I have a good relationship with them. And should you wish to talk about the info - please feel free to contact me directly at bmoser@bww.com
WIll be praying for each of you and God's Discernment as you search for drections!
God Bless ... Bill M. - Greensboro NC
