How does leukemia affect the respiratory system?

Leukemia can affect the respiratory system primarily through its impact on the immune system and the production of blood cells. The disease can lead to anemia, which reduces oxygen delivery to tissues, causing fatigue and shortness of breath. Additionally, leukemic cells can infiltrate the lungs or cause infections due to a compromised immune response, leading to respiratory complications such as pneumonia. These effects may result in increased respiratory distress and reduced overall lung function.
