Preventing Infections in Cancer Patients
Cancer patients who are treated with chemotherapy are more likely to get infections. One out of every 10 cancer patients who receives chemotherapy gets an infection that requires a hospital visit.
The immune system helps your body protect itself from getting an infection. Cancer and chemotherapy can damage this system by reducing your number of infection-fighting white blood cells. Find out from your doctor when your white blood cell count is likely to be lowest, since this is when you’re most at risk for infection. This usually occurs between 7 and 12 days after you finish each chemotherapy dose, and may last as long as one week.
How to Prevent Infections During Chemotherapy
Watch Out for Fever
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.
Take your temperature any time you feel warm, flushed, chilled, or not well. If your temperature is 100.4°F (38°C) or higher for more than one hour, or 101°F (38.3°C) or higher for any length of time, call your doctor right away.
Wash Your Hands Often
Clean hands help prevent infections. Many diseases are spread by not washing your hands, which is especially dangerous when you’re getting chemotherapy treatment. You and anyone who comes around you, including family members, doctors, and nurses, also should wash their hands often. Don’t be afraid to ask people to wash their hands. Use soap and water to wash your hands. If soap and water aren’t available, use an alcohol-based hand sanitizer.
