First time at this site. My mom - age 80 - just had biopsy done yesterday. Her doctor said he saw a white patch which he has never seen before. We get feedback in 8-10 days. She had Leukemia in 2002 - did chemo and has been free from that since 2004. She has had UTI on and off for several years - the last one for the past 5 months - many antibiotics and finally so much pain that new doctor scheduled a scope and now the biopsy. Thoughts on the white patches??? Thank you for any input.
