[/INST] Hello, It looks from your details that your relative had some vascular surgery with a bypass procedure. As she had previous uterus surgery for a malignancy then a continuous fever may be either due to:- Infection or- Spread of malignancy (Secondaries) I shall advise not to wait for this. You should consult to your doctor for complete evaluation. At present, she may have an antipyretic like paracetamol for relief. Hope I have answered your question. Let me know if I can assist you further.  </s>
