Diagnosis & Treatment of Respiratory Infections In Cancer

Patients undergoing cancer treatment (chemotherapy, immunotherapy, radiation) often have weakened immune systems, making them more vulnerable to respiratory infections like pneumonia, bronchitis, or fungal lung infections. Prompt diagnosis and treatment are critical, as these infections can become serious quickly.

Diagnosis

We use a combination of tools to identify the cause of infection:

  • Detailed medical history & physical exam
  • Blood tests and markers of infection
  • Chest X-ray or CT scan to look for lung involvement
  • Sputum culture, blood culture, or bronchoscopy to identify bacteria, viruses, or fungi
  • PCR tests for specific viruses (e.g., COVID-19, Influenza, CMV)
Management

Management includes targeted antimicrobial therapy, supportive care like oxygen, and temporary adjustment of cancer treatment when necessary.

    Why It’s Critical

    Early intervention helps prevent complications like respiratory failure, treatment delays, or spread of infection. A multidisciplinary approach between oncologists and pulmonologists ensures timely care and better outcomes.
