52 year old female, peri menopausal started about a year ago, hot flashes. hx bladder ca low grade, develop small tumors and have them removed in Dr office over past 5 years old patient Dr not concerned this is what this type of Bladder tumor does and you just remove them. I recently had a breast reduction under general anesthesia, and after that had 3 sm bladder tumors removed with a biopsy to confirm grade. They are still low grade will cont on same treatment plan. I just had blood work done and my urea nitrogen/creatinine ratio serum was elevated 31.0 urea nitrogen, blood was 24 , this has never been elevated before. wondering if anesthesia and removal of tumors could have elevated this , I am also have more frequency with hot flashes since having breast reduction. Thanks,
