29 year old female. 100 lbs, have lost 10 lbs. since October. Had a US in Oct. that picked up an echogenic focus, "most likely representing a cavernous hemangioma 3.4 cm". (Dec) Follow up CT with in contrast states "probable focal fatty infiltration" 4 cm. I also have high bilirubin. All other liver function tests are normal. I am concerned, but doctors do not seem to be. Apart from this I have been very ill since the end of September with digestive problems, weight loss, headaches, etc. Should I be worried about cancer?
