Overview

Reduced chest expansion occurs when pleural thickening or effusion prevents the lungs from fully expanding. Patients may notice one side of the chest moves less than the other during breathing.

Prevalence: Common in advanced pleural mesothelioma

Mesothelioma Types Associated With Reduced Chest Expansion

  • Pleural mesothelioma

What Causes Reduced Chest Expansion in Mesothelioma?

→ Pleural thickening
→ Pleural effusion
→ Tumor restricting lung expansion
→ Chest wall involvement

When to See a Doctor

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

  • Noticeable asymmetry in chest movement
  • Unable to take deep breaths
  • Worsening breathing capacity

Connection to Asbestos Exposure

Reduced Chest Expansion 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 reduced chest expansion, 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 reduced chest expansion or other symptoms, early evaluation is important.
