Its tumors continue to develop and their survival is predicted to be less than one month. She has had colostomy and her mobility has been limited to wheelchairs. Dr. Prasanta K Ray, an immunologist and biochemist at the University of Pennsylvania in Philadelphia, and his research team performed surgery on this inoperable cancerous woman, cut the abdomen again, and gave a series of immunoadsorption treatments.
