Overview

Shortness of breath (dyspnea) is the most common symptom of pleural mesothelioma, affecting approximately 79% of patients at diagnosis. It occurs when tumors or fluid buildup (pleural effusion) compress the lungs, reducing their capacity to expand fully.

Prevalence: 79% of pleural mesothelioma patients

Mesothelioma Types Associated With Shortness of Breath

  • Pleural mesothelioma (most common)
  • Pericardial mesothelioma

What Causes Shortness of Breath in Mesothelioma?

→ Pleural effusion (fluid around lungs)
→ Tumor growth restricting lung expansion
→ Thickening of the pleural lining
→ Reduced lung capacity

When to See a Doctor

Seek medical attention if you have a history of asbestos exposure and experience:

  • Breathlessness during normal activities
  • Waking up short of breath
  • Needing to sit upright to breathe
  • Rapid, shallow breathing

Connection to Asbestos Exposure

Shortness of Breath in the context of mesothelioma is directly linked to prior asbestos exposure. The latency period between asbestos exposure and symptom development averages 20-50 years. If you worked in industries with asbestos exposure (such as construction, shipbuilding, automotive repair, or military service) and experience shortness of breath, inform your doctor about your exposure history.

Early detection of mesothelioma significantly improves treatment options and outcomes. Patients diagnosed at earlier stages have access to surgical options and multimodal treatments that can extend survival.

Concerned About Your Symptoms?

If you have a history of asbestos exposure and are experiencing shortness of breath or other symptoms, early evaluation is important.
