What should be done when someone with hairy cell leukemia develops a fever of 101°F after months of no symptoms?

A fever of 101°F in someone with hairy cell leukemia (HCL) should be taken seriously and addressed promptly. Because HCL affects the immune system, the body becomes more vulnerable to infections — including bacterial, fungal, and viral infections.

Here's what to do right away:

- Contact the doctor or care team immediately — even if it's after hours, most oncology teams have an on-call line for situations like this
- Do not wait to see if the fever goes away on its own — in people with HCL, fevers can signal a serious infection that needs quick attention
- Head to the emergency room if the doctor cannot be reached quickly or if other symptoms appear, such as chills, difficulty breathing, or confusion People with HCL have a compromised immune system due to changes in their blood cells. This makes infections more likely and potentially more serious than in someone without leukemia.

A fever is one of the known symptoms of HCL and can also be a sign that something needs medical attention. The care team will likely want to run blood tests to check blood cell levels and look for signs of infection.

Please don't delay — getting medical advice today is the right move. Wishing your brother well. 💙
