I read about your story on cnn.com. Kimberly Fowler, like you, was diagnosed with brain cancer over 25 years ago, and found her own miraculous cure, outside of medical predictions, which had her terminal within a year. She has a wonderful story, which might be able to guide you in your decision. After a successful legal career, she founded YAS Fitness Centers. She is the creator of Yoga for Athletes & author of The No OM Zone, and can be reached at 1101 Abbot Kinney Blvd, Venice, California 90291 USA. She has received widespread media coverage on TV, in print and online from CNN Health, ABC’s Good Morning America and FOX Business to The New York Times, Glamour, Shape, Yoga Journal, Prevention Magazine and many more.

She would be someone to talk to about your condition.
