How Pleural Biopsies Confirm Mesothelioma Diagnosis

Legally Reviewed by Joseph P. Williams on September 17, 2025

When doctors suspect pleural mesothelioma, they need definitive proof before starting treatment, and that proof comes through a pleural biopsy. This critical diagnostic procedure allows medical professionals to examine tissue from the pleura (the lining around your lungs) under a microscope, providing the concrete evidence needed to confirm or rule out this aggressive cancer caused by asbestos exposure.

The Williams Law Firm, P.C. understands the overwhelming nature of mesothelioma diagnosis and the complex medical procedures involved. Our founding partner, Joseph P. Williams, has spent 30 years fighting for mesothelioma patients and their families, and we have never lost a mesothelioma case. We know that understanding your diagnosis is the first step toward both medical treatment and pursuing the compensation you deserve.

What Are the Different Types of Pleural Biopsies?

Several biopsy methods can confirm mesothelioma, each with specific advantages depending on your situation. 

Needle Biopsy

A needle biopsy, also called a pleural tap or thoracentesis, involves inserting a thin needle through your chest wall to extract fluid and small tissue samples from the pleural space. While this minimally invasive approach causes less discomfort, it may not always provide enough tissue for a definitive diagnosis.

Surgical Biopsy

For more comprehensive results, doctors often recommend surgical biopsies. Video-assisted thoracoscopic surgery (VATS) allows surgeons to insert a small camera and instruments through tiny incisions in your chest, providing direct visualization of the pleura while collecting larger tissue samples. 

Open Surgical Biopsy

Open surgical biopsies, though more invasive, offer the most extensive tissue collection when other methods prove insufficient.

The Biopsy Process and What You Can Expect

Before your biopsy, medical staff will explain the procedure and ensure you understand what to expect. Most biopsies require some form of sedation or anesthesia, and you’ll need someone to drive you home afterward. The actual procedure time varies, needle biopsies typically take 30 to 45 minutes, while surgical biopsies may require several hours.

During the procedure, doctors will collect multiple tissue samples from different areas of your pleura. This comprehensive sampling helps pathologists identify the specific type of pleural mesothelioma cells present, which directly impacts your treatment options. The samples are immediately sent to a laboratory where specialists examine them using advanced microscopic techniques and molecular testing.

Why Biopsies Are Essential for Mesothelioma Diagnosis

Imaging tests like CT scans and X-rays can suggest mesothelioma, but they cannot provide the definitive diagnosis required for treatment planning. Only by examining actual tissue samples can pathologists distinguish mesothelioma from other conditions that may appear similar on scans, such as lung cancer or pleural plaques.

The biopsy results also determine the specific cell type of your mesothelioma. These types include the following:

  • Epithelioid
  • Sarcomatoid
  • Biphasic

The type of mesothelioma you are diagnosed with will significantly influence your prognosis and treatment approach. Additionally, pathologists can perform molecular testing on biopsy samples to identify genetic markers that may make you eligible for targeted therapies or clinical trials.

Understanding your complete diagnosis through biopsy results empowers you to make informed decisions about your care. It also provides the medical documentation necessary if you choose to pursue legal action against the companies responsible for your asbestos exposure.

Moving Forward After Your Pleural Biopsy

Receiving biopsy results can feel overwhelming, but remember that early detection often leads to better treatment outcomes. Once you have a confirmed diagnosis, your medical team can develop a personalized treatment plan that may include surgery, chemotherapy, radiation therapy, or innovative treatments available through clinical trials.

While focusing on your health remains the top priority, it’s also important to understand your legal rights. The companies that exposed you to asbestos knew about its dangers but failed to protect workers and consumers. You deserve compensation for your medical expenses, lost income, and the pain and suffering you’ve endured.
