SUBJECT: ClinicalTrials.gov - Question - general information
MESSAGE: A friend had chemo for breast cancer.  She has developed a foam in her mouth that appears to come from her gums.  She has been to every doctor, but no one can diagnose.  She has tried everything recommended and nothing seems to work.  She has gone into a deep depresstion because of this constant foam.  Would there be any studies available?  Could someone give an idea of what could be causing this problem in her mouth?  Is there any interest of looking into her case?  Thank you.
