[|Human|] good day doc. My sister has bone cancer on her pelvis and on one of her left rib. She was discharged from the hospital two days ago with pain management medications prescribed by her physician. She had slightly low hemoglobin and WBC in her CBC while she was confined in the hospital. Now she has manifested fever which rapidly rises to 40.5 Celsius and rapidly drops back to normal after 30 minutes after giving her paracetamol. What could be the possible cause in this sudden rise and fall of her temperature? She had two episodes already. Could this be related to her cancer advancing or due to an infection? Thank you.
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your sisters situation and problem. Cancer patients are at great risk of infection because of poor immunity. So causes of on-off fever in cancer patient are1. Infection2. Release of chemical substance (cytokines and progeny) from the tumor. If Infection has been ruled out then tumor itself can cause fever by releasing cytokines and progeny from tumor mass. So give her paracetamol whenever she is having fever. No need to worry as this is normal in cancer, but better to rule out infection first.
