Diaphragm Tumor

At the Center for Thoracic Oncology at Boston Medical Center, we treat a broad range of conditions, including tumors in the diaphragm. We combine medical excellence, technologically advanced facilities and equipment, and a patient-centered approach to provide fast, accurate diagnoses and effective treatments.

What is a Diaphragm Tumor?

The diaphragm is a dome-shaped muscle located between your abdomen and your chest cavity (thorax). It is the muscle that allows air to flow in and out of your lungs by decreasing pressure in the lungs and helping the rib cage expand when you inhale. Tumors can develop in the diaphragm, which can be malignant (cancerous) or benign (non-cancerous). These tumors may originate in the diaphragm or spread from elsewhere.

What are the Symptoms of a Diaphragm Tumor?

Symptoms vary based on the type of disorder, but may include:

• Discomfort or difficulty with breathing
• Pain in the chest, shoulder, or abdominal area
• Hypoxemia, or a deficiency of oxygen in the blood
• Decreased breath sounds
• Paralysis, in rare cases
