My FBC is normal. I then had a liver biopsy for which the result came back as undifferentiated cells and and therefore, undifferentiated tumour. I asked what type is the tumour and was just told, undifferentiated. I have since been told that the hospital does not have a firm diagnosis and also they are only surmising that the liver lesion is a metastases from whatever is in my lung. Has anyone else had any experience of an undifferentiated tumour and do you know if this is a definate malignancy ?.Many thanks, Sue . I  Britmissy Wed, 02 May 2007 00:00:00 GMT
