My mother has got a renal mass in her right kidney approx 7cm and what we understood by her reports was that she has tiny multiple cysts in her lower pole, the doctor has told us that it is not malignant and non enhancing, but we have just done a ct scan and blood tests not even any biopsy so how can he be so sure it is not malignant, she seldom gets a lower back painin her right side, we are taking her to another consulting doctor for a second opinion, as to no what should be done, she is also type 2 diabetic
