I am incredibly worried since blood tests that were taken following a kidney infection revealed abnormal liver function. I was subsequently referred to hospital for an ultrasound which showed a small solitary, well-defined mass in my liver and I now have to for a CT scan. I am terrified that this is cancer. My hospital report says ESR 38, CRP 118. It does not mention that the mass looks cancerous but says that it is does not appear to be typical of a haemangioma, cyst or abscess. The pancreas, gall bladder, bile duct, kidneys, spleen and aorta appear normal. The GP says that she just does not know what it is.
