How Chemotherapy Affects Your Immune System in Mesothelioma
This is an important question, and understanding how chemotherapy impacts your immune system will help you prepare for treatment and recognize what to expect.
How Chemotherapy Works (and Why It Affects Immunity)
Chemotherapy drugs work by targeting and killing rapidly dividing cells—which includes both cancer cells AND some of your healthy cells. Your immune system cells, particularly white blood cells, divide very quickly to fight infections and protect your body. This means chemotherapy can damage these protective cells as a side effect.
The main immune cells affected are:
- Neutrophils (infection-fighting white blood cells)
- Lymphocytes (cells that coordinate immune responses)
- Platelets (cells that help with blood clotting)
When these cells are reduced, your body becomes more vulnerable to infections—a condition called immunosuppression.
What This Means Practically
During and shortly after chemotherapy cycles, you may experience:
- Increased infection risk - Even minor cuts or common bacteria can become serious infections
- Delayed wound healing - Your body has fewer resources to repair injuries
- Reduced ability to fight off colds, flu, or other illnesses
- Fatigue - Your immune system working hard while also being compromised is exhausting
Timeline of Immune Recovery
Your immune system typically recovers between chemotherapy cycles, which is why treatment is usually given in intervals (for example, one week of treatment followed by 2-3 weeks of recovery). However, repeated cycles can make recovery slower over time.
Questions to Ask Your Mesothelioma Care Team
Since your specific treatment plan depends on your individual case, ask your oncologist:
- Which chemotherapy drugs will I receive, and how do they specifically affect white blood cell counts?
- What are my expected white blood cell counts during treatment, and when should I call if I develop symptoms of infection (fever, chills, unusual fatigue)?
- Will I need growth factor injections (like G-CSF) to help my bone marrow produce more white blood cells faster?
- What precautions should I take at home to reduce infection risk during low-immunity periods?
- Are there any immune-supporting supplements or dietary changes you recommend during treatment?
Important Context
The good news is that your medical team monitors your blood counts regularly during chemotherapy. If your white blood cell counts drop too low, they can adjust your treatment schedule or use supportive medications to help your immune system recover more quickly.
