Symptoms of Infection

Watch Out for Fever

Take your temperature any time you feel warm, flushed, chilled, or not well. If you get a fever during your chemotherapy treatment, it’s a medical emergency. Fever may be the only sign that you have an infection, and an infection during chemotherapy can be life-threatening.

Know the Symptoms of Infection

Call your doctor right away if you notice any symptoms of an infection, such as a fever, cough, sore throat, nasal congestion, redness or swelling in any area, diarrhea, or vomiting.
