Managing Infections During Lung Cancer Treatment

Infections are an important concern during lung cancer treatment because many therapies can temporarily weaken your immune system. Here's what you should know:

Why Infections Are a Risk

During lung cancer treatment—whether chemotherapy, radiation, immunotherapy, or combinations—your body's ability to fight off infections can be compromised. Your white blood cells (which normally protect you) may be reduced, making you more vulnerable to bacterial, viral, and fungal infections.

What You Should Do

1. Know the Warning Signs

Watch for symptoms that may indicate an infection:

  • Fever (temperature of 100.4°F or higher)
  • Chills or sweating
  • New or worsening cough
  • Shortness of breath
  • Sore throat or mouth sores
  • Burning during urination
  • Unusual fatigue or weakness
  • Any new or unexplained symptoms

2. Report Symptoms Immediately

According to the NCCN Guidelines for Patients, it's critical to "let your treatment team know about any new or worsening symptoms." Don't wait for your next scheduled appointment—call your doctor right away if you develop signs of infection, especially fever.

3. Practice Prevention

  • Wash your hands frequently and thoroughly
  • Avoid close contact with people who are sick
  • Avoid large crowds during treatment
  • Keep your living space clean
  • Practice good oral hygiene (infections often start in the mouth)
  • Avoid raw or undercooked foods
  • Stay up-to-date on recommended vaccinations (ask your team which are safe during treatment)

4. Discuss Prevention with Your Care Team

Ask your oncology team about:

  • Whether you need preventive antibiotics or antifungal medications
  • Which vaccinations are appropriate for you
  • Specific precautions based on YOUR treatment plan
  • When to seek emergency care versus calling the office

Questions to Ask Your Healthcare Team

  1. What specific infection risks come with my treatment plan?
  2. What symptoms should I report immediately versus waiting for my next appointment?
  3. Do I need any preventive medications during treatment?
  4. Are there vaccinations I should get before, during, or after treatment?
  5. What's the best way to reach you if I develop symptoms after hours or on weekends?

Important Reminder

Your oncology team has protocols specifically designed to manage infection risk during your treatment. They'll monitor your blood counts and adjust your care as needed. The key is staying alert to symptoms and communicating promptly with your healthcare providers.
