Mesothelioma Diagnosis

Written by Dr. Jeffrey Velotta, MD, FACS | Edited by Walter Pacheco | Last Update: | 29 Min Read

Doctors typically start the mesothelioma diagnostic process with a physical exam and imaging tests, then they run blood work and fluid analysis. Still, only a biopsy accurately confirms mesothelioma cancer.

Expert & Survivor Perspectives

“If you can catch [mesothelioma] earlier on, the idea is you can intervene and do more treatment, whether it’s surgery, chemotherapy or immunotherapy. And so the earlier we catch it, the more chance you have for living longer.”
Dr. Jeffrey Velotta, thoracic surgeon

“In the beginning, I think the biggest challenge of a mesothelioma diagnosis is that patients are just shocked. So when they come to us, we give them a step-by-step guide on what they need to do first: getting their medical treatment plan in place, finding the right doctor, educating them about the disease and providing emotional support.”
Amy Pelegrin, Hospice Care Director for The Mesothelioma Center

“I had difficulty sleeping at night because of pain in my back and in my chest cavity. I was also beginning to exhibit a rough cough. Over a period of a couple of months, it became more persistent. At the time, we were very busy at work, and I continued to work and ignore it. …I became sick. Really felt bad. …I went to see my general practitioner… The doctor told me to go to the hospital. They drew fluid off of the lung, the right lung. …They admitted me. After three days, they told me the diagnosis was mesothelioma. We didn’t know what mesothelioma was.”

Expert Insights

Dr. Snehal Smart: How Doctors Test for Mesothelioma

Dr. Snehal Smart, in-house medical doctor at The Mesothelioma Center and Board-Certified Patient Advocate, explains how the process of diagnosing mesothelioma starts with imaging tests and ends with a biopsy.

0:57

The first test for a patient with, symptoms related to mesothelioma will be going to their primary doctor, getting an x-ray or a CAT scan done. Based on the results from that, they may go through further testing such as a thoracentesis or paracentesis, which is where they drain fluid, whether it’s from the lining of the lungs or the peritoneal area, which is the abdominal area. The next step would be for a biopsy.

The biopsy is a step where they confirm the diagnosis. This sample is sent to a pathologist who ultimately tests the sample taken out from the tumor and identifies it as mesothelioma.

Diagnostic Process

How Is Mesothelioma Diagnosed?

Doctors typically diagnose mesothelioma using a combination of imaging tests, blood tests, fluid analysis and biopsies to confirm this rare asbestos-related cancer. For many people, mesothelioma diagnosis begins with a physical exam when symptoms appear. For those with a known history of asbestos exposure, doctors will run screening tests before signs of mesothelioma develop. For others, mesothelioma is sometimes found incidentally during tests or procedures for unrelated conditions.

Once your doctor suspects mesothelioma, they’ll typically refer you to an oncologist. From there, you can expect imaging tests to determine where tumors are located and how far they’ve spread, and your oncologist will also listen for signs of fluid buildup. Because mesothelioma symptoms resemble those of other conditions, getting the right specialists involved early matters.

“Just because your doctor told you that you have fluid around the lung does not necessarily mean you have mesothelioma,” said Dr. Jacques Fontaine, thoracic surgeon and director of the Mesothelioma Research and Treatment Center at Moffitt Cancer Center. “Even if you have asbestos exposure, you need to look further into it. Very often, you need a surgical biopsy or a core biopsy to make sure that you indeed have mesothelioma.”

Diagnostic Tests

Mesothelioma Diagnostic Tests

The most important mesothelioma diagnostic test is a biopsy. Typically, this is the last test a doctor performs after they’ve run physical exams, blood tests and imaging tests.

Key Tests to Diagnose Mesothelioma

  • Biopsies
  • Blood tests
  • Fluid analysis
  • Imaging tests
  • Medical history and physical exam

If you or a loved one has a history of asbestos exposure, you should consult your doctor about running these tests. An early diagnosis leads to more treatment options and improved prognosis and life expectancy.

Medical History and Physical Exam

See your doctor if you have chest pain, trouble swallowing, shortness of breath or back pain and believe you’re at risk for mesothelioma. You could be at risk for mesothelioma if you’ve worked in construction, shipbuilding or military service, or lived with someone who worked with asbestos products.

Your doctor will discuss your medical history and ask about your asbestos exposure. Afterward, your doctor will perform a physical exam, checking for symptoms of mesothelioma, such as fluid buildup in your chest (pleural effusion) or in your belly (ascites). They’ll check for fluid around your heart (pericardial effusion). In rare cases of testicular mesothelioma, they’ll perform a physical examination of the groin area.

Imaging Tests for Mesothelioma

Radiologists use mesothelioma imaging tests, including PET scans, X-rays, echocardiograms, CT scans and MRIs, to locate and assess mesothelioma tumors. Imaging tests can show tumor size, location and possible spread, but they can’t confirm mesothelioma on their own.

Types of Mesothelioma Imaging Scans

  • Computed tomography (CT) scans: CT scans produce high-resolution cross-sections with detailed views of possible tumors in the chest and abdomen.
  • Echocardiograms: A noninvasive procedure, echocardiograms use ultrasound to create an image of the heart’s movement.
  • Magnetic resonance imaging (MRI) scans: MRIs use a strong magnetic field and radio waves to form detailed images of the person’s soft tissues.
  • Positron emission tomography (PET) scans: PET scans use an injected radioactive tracer to find cancer cells. PET/CT scans combine both as a more comprehensive tool.
  • X-rays: These are most likely the first imaging test done. X-rays can identify pleural or peritoneal tumors. X-rays only provide a 2D view.

Doctors use scan results to decide where to take tissue samples during a biopsy. Some scans involve contrast dye. Most scans are generally quick and painless. MRIs can take 30 to 90 minutes.

Blood Tests

Doctors sometimes order blood tests, such as the MESOMARK blood test, as part of the mesothelioma testing process. These tests look for certain proteins, white blood cell levels and other possible signs called biomarkers. Because these markers can be associated with other conditions too, blood tests can suggest mesothelioma but can’t confirm cancer on their own.

In 2025, the American Society of Clinical Oncology began recommending genetic testing. Genetic testing often involves blood and saliva tests. A 2024 review reports up to 10% of patients diagnosed with mesothelioma have what’s known as a BAP1 mutation. They tend to respond better to chemotherapy. Patients with this mutation have a median survival of 5 years.

Fluid Analysis (Cytology Tests)

Mesothelioma cytology tests help doctors find cancer cells in fluid. Doctors collect samples from effusions or ascites from the chest, abdomen or around the heart. Then, they use a microscope to search for mesothelioma cells. If they find these cells, it helps them diagnose mesothelioma.

Types of Mesothelioma Cytology Tests

  • Paracentesis: Doctors insert a needle into your belly to remove fluids for testing. This test is common for people with peritoneal mesothelioma.
  • Pericardiocentesis: A needle is inserted into your chest to remove fluid from around your heart. This test is common for those with pericardial mesothelioma.
  • Thoracentesis: Doctors insert a needle into your chest. This procedure is common for people with pleural mesothelioma.

Both cytology tests and biopsies help diagnose mesothelioma, according to a 2024 study published in the Journal of the American Society of Cytopathology. The key difference between the two tests is that cytology tests look at fluid, while biopsies take tissue samples. Biopsies give more information about cancer cells, which is how doctors determine whether you have mesothelioma.

Biopsies

A biopsy is the best test for confirming a mesothelioma diagnosis. This medical procedure involves taking a tissue sample, which is examined under a microscope to check for cancer cells. Doctors suggest a biopsy if you show signs of mesothelioma.

Types of Mesothelioma Biopsy Procedures

  • Laparoscopy: Doctors make a small cut in the abdomen and use a tiny camera and tools to take a tissue sample. This type of endoscopic biopsy is best for peritoneal mesothelioma.
  • Mediastinoscopy: A small cut is made above your breastbone, then doctors use a tube with a light to see and take tissue. This is for biopsies of the lymph nodes and around the windpipe for pleural mesothelioma.
  • Core needle biopsy: A thin needle is put through your skin to take a small piece of tissue. Also known as a fine-needle aspiration, it’s used to obtain tissue samples that are difficult to collect.
  • Surgical biopsy: Surgeons make a larger cut to remove a tissue sample when other methods don’t work. This is used when an endoscopic or core needle biopsy isn’t possible.
  • Thoracoscopy: Doctors make a small cut in the chest, then use a tube with a camera to examine the area and take tissue samples. This is the most accurate biopsy for diagnosing pleural mesothelioma. Laparoscopy and mediastinoscopy may be used depending on where the tumors develop.

“The diagnosis of mesothelioma is very difficult. The majority of the time, 60% to 70% of the time, fluid will not tell you if you have mesothelioma,” said Dr. Jeffrey Velotta. “There just aren’t enough cells in the fluid. You actually need tissue. I recommend all patients undergo biopsy as soon as possible and not wait.”

Diagnosis Timeline

What the Path to a Mesothelioma Diagnosis Looks Like

The path to a mesothelioma diagnosis isn’t the same for everyone. Different symptoms lead doctors to different tests. Results of one test may lead to additional tests, and sometimes, other doctors perform those tests. But typically, a diagnosis may take 90 days before a mesothelioma specialist’s final confirmation.

  1. Day 1

    Initial symptoms appear.

  2. Day 2

    X-rays identify fluid buildup.

  3. Day 3 - Day 13

    Antibiotic prescribed to treat pneumonia or fluid drained.

  4. Day 14

    Doctor orders follow-up X-rays, asks patient to return in 30 days.

  5. Day 44

    Follow-up X-rays show fluid buildup again. Doctor either drains fluid, orders PET scans and CT scans.

  6. Day 54

    Imaging scans show a possible underlying cause. Patient referred to surgeon or pulmonologist, which can take up to 15 days.

  7. Day 69

    Surgeon, pulmonologist or both schedule a biopsy appointment, which can take up to 10 days.

  8. Day 79

    Surgeon, pulmonologist or both take biopsy, which typically requires a hospital stay of 1-2 days. The biopsy results, also known as pathology, can take up to 10 days.

  9. Day 89

    (Approximately three months later): Mesothelioma is confirmed if biopsy tests positive for the disease.

Staging

Staging Mesothelioma Cancer

Mesothelioma staging is part of the diagnostic process. It describes how far tumors have spread, as seen on imaging scans. The 4 stages of mesothelioma range from early stage (stages 1 and 2) to late stage (stages 3 and 4). The higher the number, the more the cancer has spread from where it originated.

Staging helps doctors plan the best treatment. An early-stage mesothelioma diagnosis improves treatment options. A late-stage mesothelioma diagnosis makes these treatments less effective. Later stages become more difficult to treat.

The TNM staging system is the official method for staging pleural mesothelioma. It describes tumor size (T), lymph node involvement (N) and cancer spread to distant organs or metastasis (M), helping doctors plan the most effective treatment. The current standard is the 9th edition of the TNM Classification for Pleural Mesothelioma, updated in 2024.

Dr. Andrea Wolf, thoracic surgeon and director of the New York Mesothelioma Program at Mount Sinai, tells us, “When staging mesothelioma, I assess where the cancer is located, how far it has spread, and which organs are involved. This information is essential in developing the most effective treatment plan for each of my patients.”

Mesothelioma Cell Types and Diagnosis

As part of the staging process, pathologists examine biopsy tissue under a microscope to confirm mesothelioma and also identify the specific cell type. It’s a key part of a mesothelioma diagnosis because cell type affects prognosis and determines which treatments are most effective.

Mesothelioma Cell Types Identified Through Biopsy

  • Biphasic: A mix of epithelioid and sarcomatoid cells, found in 20% to 35% of cases. Treatment outcomes depend on the proportion of each cell type.
  • Epithelioid: The most common cell type, found in 50% to 70% of cases. People with epithelioid mesothelioma typically have the best prognosis and respond well to surgery and chemotherapy.
  • Sarcomatoid: The rarest and most aggressive cell type, found in 10% to 20% of cases. Sarcomatoid mesothelioma is harder to treat with surgery.

Mesothelioma cell type identification relies on immunohistochemistry, a technique that allows doctors to classify tumor cells as epithelioid, sarcomatoid or biphasic. Once doctors identify the cell type, they can decide which mesothelioma treatment is best for the patient.

Challenges of a Misdiagnosis

Why Is Diagnosing Mesothelioma Difficult?

Diagnosing mesothelioma is difficult because its symptoms mimic more common illnesses like bronchitis or pneumonia. The latency period between asbestos exposure and mesothelioma can be 20 to 50 years. So when symptoms show up decades later, an asbestos-related disease like mesothelioma may not immediately be identified.

Mesothelioma misdiagnosis is common. The Mesothelioma Center’s 2025 Patient Survey found that more than 17% of survey respondents were misdiagnosed, which led to delayed treatment and adverse impacts on their health. Some patients said they were misdiagnosed with pneumonia, COPD, lung cancer or heart problems.

On average, it takes about 3 months from the first appearance of symptoms to a confirmed diagnosis. Because many doctors are unfamiliar with this rare malignant cancer, getting a second opinion from an asbestos-related cancer expert is so important if you’ve had a history of asbestos exposure. But some people aren’t aware they’ve been exposed, making it even more challenging.

Peritoneal mesothelioma survivor Tamron Little knows firsthand the importance of a second opinion. “At first, I was under the care of an oncologist who said he knew nothing about mesothelioma. But I finally found the right mesothelioma specialist,” Tamron said. “I was presented with a roadblock and decided to go around it.”

Early Detection

Importance of Early Mesothelioma Detection

Finding mesothelioma early is critical because it allows doctors to start treatment sooner. An early diagnosis and guidance from a mesothelioma specialist can offer more treatment options and better outcomes. This can improve survival and quality of life.

However, according to the Centers for Disease Control and Prevention, early detection is still rare. About 71% of mesothelioma cases are diagnosed after stage 1, according to a CDC study.

Pleural mesothelioma survivor Kevin Hession is an unusual example of someone diagnosed early. He tells us, “After my surgery, I was told my mesothelioma was stage 1-B.” His diagnosis in 2021 followed 4 cases of pleurisy, which is inflammation around the lungs. Ongoing chemotherapy is helping him manage the disease.

Treatments

Treatment Options After a Mesothelioma Diagnosis

A confirmed diagnosis and cell type help your specialist build a mesothelioma treatment plan. The next steps may also include choosing a specialist, preparing for treatment and finding support for you and your family. What to do after a mesothelioma diagnosis can vary based on your individual needs and circumstances. Your care team may recommend surgery, chemotherapy, immunotherapy, radiation or a combination of these treatments.

Primary Mesothelioma Treatment Options

  • Surgery

    Removes visible tumors; most effective in early-stage disease.

  • Chemotherapy

    Systemic drugs that shrink tumors and slow spread.

  • Immunotherapy

    Helps the immune system recognize and attack cancer cells.

  • Radiation

    Targets tumors to control growth and relieve symptoms.

  • Multimodal therapy

    Combines surgery, chemotherapy and radiation.

  • Clinical trials

    Access to emerging therapies not yet widely available.

FAQs

Common Questions About Diagnosing Mesothelioma

People with a history of asbestos exposure and symptoms such as chest pain or shortness of breath should ask their doctor about testing for mesothelioma. They may recommend imaging scans, blood tests and a biopsy to diagnose mesothelioma.

The average time to get a mesothelioma diagnosis is about 3 months. This is after the first symptoms appear. The most common symptoms include shortness of breath and chest pain.

The first step in preparing for a mesothelioma biopsy is to stop all blood-thinning meds at least 5 days before your biopsy. Don’t eat or drink anything 6 hours before your appointment. Wear loose clothes to the appointment. Also, arrange for a designated driver to take you home. Plan to spend several hours undergoing the biopsy. Some biopsies need at least one night in the hospital.

People with mesothelioma may not know they have the cancer until 20 to 50 years after asbestos exposure. Even after symptoms first show, they can be mistaken for common illnesses, so diagnosis can take months or longer. If you’ve been exposed to asbestos, tell your doctor, even if you feel healthy.

Most insurance plans cover second opinions, and Medicare Part B covers a second opinion before surgery. Some plans require a referral or an in-network doctor, so call your insurer before you book. Our Patient Advocates can help you check coverage and find mesothelioma specialists who accept your plan.
