Managing Infections During Lymphoma Treatment

Infections are a significant concern during lymphoma treatment because many therapies (chemotherapy, targeted drugs, and immunotherapies) can weaken your immune system. Here's what you need to know:

Why Infections Are a Risk

During lymphoma treatment, your white blood cell count often drops—a condition called neutropenia. White blood cells are your body's infection fighters, so when their numbers are low, you're more vulnerable to bacterial, viral, and fungal infections. According to NCCN Guidelines for Lymphoma, understanding this risk is an essential part of your supportive care plan.

Key Steps to Take

1. Know Your Risk Level

Ask your oncology team:

  • "What is my current white blood cell count?"
  • "Am I at high risk for infections based on my treatment plan?"
  • "What symptoms should I watch for?"

Your risk varies depending on your lymphoma type, treatment stage, and overall health.

2. Watch for Warning Signs

Contact your care team immediately if you develop:

  • Fever (temperature of 100.4°F/38°C or higher)
  • Chills or sweating
  • Sore throat or mouth sores
  • Cough or difficulty breathing
  • Burning during urination
  • Unusual redness, warmth, or drainage from cuts or wounds
  • Severe fatigue or dizziness

Don't wait to see if symptoms improve on their own. Infections can progress quickly during treatment.

3. Practice Prevention

  • Wash hands frequently with soap and water, especially before eating and after using the bathroom
  • Avoid crowds and people who are sick
  • Stay up-to-date on vaccinations (ask your team which vaccines are safe during treatment)
  • Avoid raw or undercooked foods, unpasteurized dairy, and unwashed produce
  • Keep your environment clean, especially bathrooms and kitchen areas
  • Avoid contact with people recently vaccinated with live vaccines (like flu nasal spray)
  • Practice good oral hygiene with a soft toothbrush

4. Communicate with Your Care Team

  • Report any signs of infection immediately
  • Tell your doctor about any sick contacts
  • Discuss preventive medications (like antibiotics or antifungals) if recommended
  • Ask about G-CSF (growth factors) that may help boost white blood cell production

5. Understand Your Treatment Plan

According to NCCN Guidelines for Lymphoma, supportive care—which includes infection prevention and management—is a critical part of your overall treatment strategy. Your team may:

  • Monitor your blood counts regularly
  • Prescribe preventive antibiotics or antifungals
  • Adjust your treatment schedule if counts are dangerously low
  • Recommend hospitalization if you develop a serious infection

Questions to Ask Your Oncology Team

  1. "What is my specific infection risk based on my lymphoma type and treatment?"
  2. "What symptoms require immediate medical attention?"
  3. "Should I take any preventive medications?"
  4. "How often will my blood counts be checked?"
  5. "What should I do if I develop a fever at night or on a weekend?"
  6. "Are there foods I should avoid during treatment?"
  7. "Can I receive vaccines during my treatment?"
