My husband has a couple of tumors on his kidneys. I inquired at sensiblehealth.com if Liver Flushing would be helpful. The response I received was if the tumors were beneign it would be okay. If the tumors were malignant, then it would not be helpful, and may irritate the tumors and spread the cancer to other areas of the body. Don't know if this information will help you or not, as you area dealing with cancerous cells rather than tumors, but I thought I would pass it along.
