<s>[INST] Last year I had a cancerous tumour removed from my colon, which thankfully hadnt spread.  However, I had chemo as a precaution.  This year I had operation for a strangulated hernia.  My liver profile blood tests show that it is raised.  What could be the cause for this please? [/INST] HIT hank for asking to ChatDoctorI really appreciate your concern the liver enzymes are very fluctuating one some unknown cause could change value of these enzymes even certain diet also changes the value of these enzymes here you have a history of malignancy, so this could be a cause of change of liver enzymes value, you need to correlate this with the clinical condition, hope this information helps you, take care and have nice day. </s>
