<human>: Hello, I am a stage 1 breast cancer survivor. My oncologist ran blood work and my total bilirubin levels were elevated at 2.0. I understand the normal range is 1.0 I checked old blood work and for like 5 years my levels of bilirubin have been elevated. In 2009, they were 2.0 and 2008, 1.8 and 1.1. What could be the cause of this elevation? What organ should I worry about-- liver? gall bladder? colon? kidney? pancreas? Could it be cancer? I am very worried and don t know how to proceed. Should i consult a gastroenterologist . I am also having a colonoscopy next week? Can they look while i am under anesthesia? What would the procedure be called?
<bot>: Hi, to detect particular pathology both direct and indirect bilirubin to be measured separately. Then obstructive or hepatocellular jaundice can be ruled out. Breast cancer has a chance to spread to liver causing early changes like increase in bilirubin and SGPT. So you should monitor them closely. You may consult a gastroenterologist, but your oncologist can guide you better. Reason of colonoscopy is not clear to me, because you have not mentioned related history. Anyway follow your doctors advise.
