Need info on clinics

I am new to this site just today. My cousin, with whom I am as close as a sister, went through chemo & radiation last year for adenocarcinoma of the cervix. She thought she had beat it, then was told about 2 months ago that it has returned in her lungs. The CT scan showed 3 spots on one lung & 2 on the other & a lung biopsy confirmed. The doctors have told her that she has about a 20% chance that very agressive and intense chemo could slow the cancer down for a few months, but that is probably the best she can hope for with conventional medicine. She is exploring diet & nutrition therapy, and lives in Henderson, Tennessee. The closest cities to her are Memphis, Nashville, and Jackson, Tennesee. Has anyone had good experiences with alternative medicine clinic using nutrition therapies in these cities?  I don't even know if it's okay to name the clinics. If not, feel free to email me if naming the clinic on a private email is allowed.
