Dr. Marcelo DaSilva: What are the symptoms of mesothelioma?

So the symptoms of mesothelioma vary greatly from the time of the initial presentation until we see the patients. Most commonly, the patients present with cough, shortness of breath, difficulty in walking, loss of stamina.

A few patients who were running five or 10 miles, all the sudden, they can't do that, or simple activities at home, such as cooking or care for yourself becomes challenging. Usually presents with a pleural effusion with fluid compressing the lung, causing all those symptoms. But it also can cause chest pain, which indicates to us that the tumor has somehow invaded the chest wall.

“The most common symptoms are: difficulty breathing, labored breathing when exercising and a dry cough. The first thing you're likely going to feel is ‘I can't breathe.’ Or for a peritoneal patient, it can be an accumulation of fluid in the tummy. That is the number one symptom for a patient with peritoneal mesothelioma.”

“A number of treatments can help ease symptoms and improve quality of life. Discuss all your symptoms with your medical team. Together, you can find the best treatment for you.”

“I started feeling pain on my left back like right in the middle. I actually thought I had a kidney stone. I saw the pulmonologist, and he said, ‘I don’t know Kim. The only thing I can think is let’s biopsy it. You keep having pain.’ I didn’t have any problems with shortness of breath. I didn’t have, coughing, excessive coughing. It was mainly the pain.”

  • Diagnosis challenge: Symptoms often mimic pneumonia, bronchitis and other common illnesses
  • First symptoms: Chest or abdominal pain, fatigue and shortness of breath are the most common early signs
  • Latency period: Symptoms typically appear 20 to 60 years after asbestos exposure
  • Most common symptom: Pleural effusion (fluid buildup around the lungs) affects most pleural mesothelioma patients
  • Most reported symptom: Fatigue affects 70% of pleural and 86% of peritoneal mesothelioma patients
  • Palliative care gap: Only 50% of patients receive palliative care to manage symptoms
  • Stage at symptom onset: Most patients don’t notice symptoms until stage 3 or 4

Most Common Mesothelioma Symptoms

Mesothelioma symptoms vary depending on where the cancer develops, but some symptoms occur across multiple types. Fatigue, pain, unexplained weight loss and fluid buildup are common regardless of the type. Our 2025 Patient Survey found fatigue was the most commonly reported symptom among people with pleural and peritoneal mesothelioma.

Common Mesothelioma Symptoms

  • Chest or abdominal pain
  • Fatigue or weakness
  • Fever or night sweats
  • Loss of appetite
  • Persistent cough or wheezing
  • Shortness of breath
  • Swelling in the chest or abdomen
  • Unexplained weight loss

Many mesothelioma symptoms also occur with more common illnesses, including pneumonia, the flu and digestive conditions. Because symptoms often don’t appear until 20 to 50 years after asbestos exposure, doctors may not suspect mesothelioma right away. Tell your doctor if you’ve worked with or around asbestos, even if that exposure happened decades ago.

Learn about mesothelioma misdiagnosis

Mesothelioma is caused by asbestos exposure, and symptoms can appear 20 to 50 years afterward. If you’ve ever worked around asbestos or lived with someone who did, it’s worth mentioning that to a doctor.

Learn about the dangers of asbestos exposure

Persistent symptoms like chest or abdominal pain, a lasting cough, or trouble breathing are worth evaluating, especially with an asbestos history.

Early Warning Signs of Mesothelioma

Shortness of breath, chest discomfort, abdominal bloating and fatigue are common early signs of mesothelioma. Because these initial symptoms are so similar to infections or less serious chronic conditions, they can go unrecognized. They also develop decades after the asbestos exposure that causes them, making it less likely this rare cancer is initially considered unless doctors are aware of an exposure history. 

Speak with your doctor about your history with asbestos and ask about regular mesothelioma screenings, which can catch early signs of disease. Regular monitoring can help identify changes that may need further evaluation. This awareness can help doctors consider mesothelioma sooner when symptoms appear.

Survivor Story

Kim Madril: What symptoms did you experience prior to your mesothelioma diagnosis?

I started feeling pain on my left back like right in the middle. I actually thought I I had a kidney stone. I woke up one early morning at 3 AM.

And I had this sharp shooting pain on the left side.

My husband jumped out of bed. He’s like, “what’s wrong?” I said, I think I’m having a kidney stone. And he’s like, alright. Let’s go to the emergency department.

I’m not one to go see doctors, and and I think really I hadn’t been to emergency department in probably 15 years or so. So we ended up there, and they said, “well, you must have passed it because we don’t we don’t see we don’t that we don’t see anything.” I was okay for probably three or four months, and then it came again.

Not to the same degree. And I was kinda like, “Oh, oh, ow, ow!” and it kept happening. And the intervals were coming closer, than than before. They weren’t as spread out.

And so my PCP finally said, “Kim, let’s let’s just, let’s just get a a cat scan. Okay?”

And I said, “oh, okay.” And the CAT scan came back. And he said, there’s something see some sort of nodule, that’s what he called it, a nodule at the base of your left lung. It’s not your kidney. It’s the bottom of your left lung. Which is right about where your kidneys are. And I thought, oh my gosh, I never never thought it would be like a lung thing.

So, I said, oh, okay. And he said, let’s watch it. Because it’s so small right now.

And I said, alright. I’m good with that. But then the pain kept happening. And he said, I’m gonna refer you to a pulmonologist.

And I saw the pulmonologist, And he said, he said, I don’t know Kim. The only thing I can think is you let’s biopsy it. It’s it’s something there. It’s some sort of mask. You keep having pain.

I didn’t have the I didn’t have any problems with shortness of breath. I didn’t have, coughing, excessive coughing.

It was mainly the pain. He said, we just need to biopsy it. So I said, alright. That sounds great.

Respiratory Warning Signs

Because pleural mesothelioma develops in the lining around the lungs, its initial symptoms are generally respiratory. Dr. Snehal Smart, a board-certified Patient Advocate, explains: “Most patients who may have pleural mesothelioma may experience chest pain, trouble breathing, coughing and shortness of breath.” 

Early Mesothelioma Symptoms

Tumors growing in the pleura cause fluid to accumulate between the lung and chest wall known as a pleural effusion. This fluid buildup makes it harder for the lungs to expand fully. This fluid buildup is often the first symptom that leads to a mesothelioma diagnosis. As pleural mesothelioma progresses, this fluid buildup and tumor growth combine to cause more noticeable breathing problems. 

Common mesothelioma symptoms and the percentage of patients experiencing these symptoms
Respiratory difficulties are the most reported mesothelioma symptoms.

Abdominal Warning Signs

Peritoneal mesothelioma develops in the lining of the abdomen, so its early signs usually center on digestion and abdominal discomfort. As tumors grow, they trigger fluid buildup called ascites, which puts pressure on the stomach and intestines.

Abdominal Warning Signs

  • Abdominal pain
  • Abdominal swelling
  • Fluid buildup (ascites)
  • Nausea
  • Weight loss

This fluid buildup and pressure on digestive organs can lead to nausea, constipation and visible swelling as the disease progresses. Peritoneal mesothelioma’s abdominal symptoms often get mistaken for digestive conditions. 

What Patient Advocates say

“Patients with peritoneal mesothelioma may experience abdominal pain and weight loss.”

Snehal Smart

Dr. Snehal Smart, patient advocate at The Mesothelioma Center

What survivors say

“It started with my stomach growing. …and it didn’t stop getting bigger. It was always liquid that was being accumulated. It’s not in the stomach. It’s in between the stomach and the skin. And that is actually caused by mesothelioma, but we didn’t know that at the time.”

Epifanio Figueroa, peritoneal mesothelioma survivor

Intermediate-Stage Symptoms

Patients often tell us that symptoms during the intermediate stages of mesothelioma begin to affect daily activities in noticeable ways. Breathing problems may worsen, abdominal pressure can increase and fatigue may make everyday tasks like walking, working or holding a conversation more difficult. Simple activities like climbing stairs, eating a full meal or sleeping through the night can become challenging.

Mesothelioma can progress differently depending on where it develops. Pleural and peritoneal mesothelioma also use different staging systems, so symptoms and treatment approaches can vary. As symptoms change, doctors may adjust treatment plans or add supportive measures to help manage them.

Respiratory Symptoms

As pleural mesothelioma advances into stages 2 and 3, breathing problems become more frequent and severe. Tumor growth and ongoing pleural effusions put more pressure on the lungs, making it harder for people to catch their breath during ordinary daily activities.

Intermediate-Stage Respiratory Symptoms

  • Chest pain that becomes more pronounced
  • Fatigue with daily activities
  • Persistent cough
  • Shortness of breath with activity
  • Trouble breathing that worsens

Pleural mesothelioma survivor Michael Cole described the change this way: after surgery, a breathing test that once let him blow out 98 of 100 candles dropped to just 3. Pacing activities and practicing deep breathing exercises helped him manage his reduced lung capacity over time. 

What doctors say

“It can’t just be up to the patient because the patient’s not gonna always feel like eating. It’s hard to do, but they need people to help them, nutritionists, family, friends, and their clinicians to really listen to them.”

Andrea Wolf

Dr. Andrea Wolf, thoracic surgeon and director of the New York Mesothelioma Program at Mount Sinai

What survivors say

“Before my illness I was very active and got quite a lot of exercise. The illness and treatments can change that experience. It’s important to do what you can do without overdoing it, and to always check with your doctor first. You know your own body better than anyone else…Push without hurting yourself.”

Mesothelioma survivor Michael Cole

Abdominal Symptoms

Abdominal pressure and fluid buildup intensify as this cancer progresses. Growing tumors and increasing ascites push against the stomach and intestines, making pain, bloating and appetite loss more constant than they were in earlier stages.

Intermediate-Stage Abdominal Symptoms

  • Abdominal pain becomes more pronounced
  • Bowel changes and worsening nausea
  • Increasing fluid buildup (ascites)
  • More noticeable weight loss

A study in Oncology in Clinical Practice found 30% to 80% of peritoneal mesothelioma patients experience abdominal distension as the disease progresses. Peritoneal mesothelioma patients at this stage often need more frequent fluid drainage procedures to manage the growing pressure.

Late-Stage Symptoms

Late-stage mesothelioma symptoms become severe and widespread as the cancer spreads to distant sites. Breathing difficulty worsens, abdominal distension becomes more pronounced and extreme fatigue and weight loss set in.

At this stage, the focus of care often shifts away from aggressive treatment to ensuring comfort and quality of life. This doesn’t mean curative treatment always automatically stops for every patient. You and your doctor will discuss your treatment goals and personalized plan.

Respiratory Symptoms

In late-stage pleural mesothelioma, tumor growth and fluid buildup put significant pressure on the lungs. Breathing becomes noticeably harder and even brief activities like talking or walking a short distance can trigger shortness of breath.

Late-Stage Respiratory Symptoms

  • Difficulty swallowing (dysphagia)
  • Hoarseness
  • Severe shortness of breath
  • Swelling of the face and arms

Managing symptoms at this stage often means combining several approaches, from fluid drainage procedures to breathing exercises and supplemental oxygen. Pleural mesothelioma patients at stage 4 typically need more frequent monitoring to manage this fluid buildup as it becomes harder to control.

Expert Insight

“Late stage means that there’s a lot more things involved. It’s gone beyond that primary location. It doesn’t mean that there’s not treatment options, it just means it’ll be a different course, perhaps surgery won’t be the first thing that is offered to the patient.”

Karen Selby
Karen Selby , registered nurse and board-certified Patient Advocate

Abdominal Symptoms 

In late-stage peritoneal mesothelioma, tumors can spread to the liver, intestines and other nearby organs. This spread causes more severe abdominal distension and can lead to complications like bowel obstruction, making digestion increasingly difficult.

Late-Stage Abdominal Symptoms

  • Bowel obstruction
  • Extreme weight loss
  • Nausea and vomiting
  • Severe abdominal swelling

Distant spread occurs in 10% to 50% of stage 4 mesothelioma cases and can reach organs beyond the abdomen, including the chest and brain. Peritoneal mesothelioma patients at this stage often need closer monitoring for complications tied to organ involvement, not just symptom relief.

Expert Insight

“Some mesothelioma patients present with stage 4 disease or metastatic disease. When we discuss treatment for metastatic or stage 4 mesothelioma, we have to look not only at the quantity of life but, more importantly, at the quality of life. It is important to provide these patients the best supportive care, make them comfortable and have dignity.“

Dr. Jacques Fontaine , thoracic surgeon and director of the Mesothelioma Research and Treatment Center at Moffitt Cancer Center.

Symptoms of Rare Mesothelioma Types

People with pericardial or testicular mesothelioma often receive a diagnosis while doctors evaluate other health concerns because the symptoms may not immediately suggest mesothelioma. Their symptoms differ from pleural and peritoneal mesothelioma because they affect different areas of the body. These rare forms of the disease account for a small fraction of all mesothelioma cases.

Pericardial mesothelioma affects the lining around the heart and can cause symptoms like chest pain and heart palpitations. Testicular mesothelioma affects the lining of the testes and typically causes a lump or swelling in the scrotum. Because these types are so rare, diagnosing them often requires a careful evaluation of symptoms, medical history and test results.

Pericardial Mesothelioma Symptoms

Pericardial mesothelioma affects the lining around the heart and is extremely rare, accounting for less than 1% of all cases. Symptoms of the disease often involve heart-related and general systemic issues. The disease’s rarity and nonspecific symptoms make it difficult to diagnose with only 150 cases existing in medical literature. 

Signs and Symptoms of Pericardial Mesothelioma

  • Cough
  • Difficulty breathing
  • Fatigue
  • Heart murmurs or palpitations
  • Low blood pressure
  • Shortness of breath lying down

Early symptoms may include fever, night sweats and weakness. Later stages can cause fluid buildup around the heart, leading to pressure and heart complications.

Expert Insight

“[Pericardial mesothelioma] patients can present with heart failure initially. It’s not unusual to diagnose pericardial mesothelioma as an incidental finding. You’re not suspecting pericardial mesothelioma.”

Dr Wicki Vigneswaran
Dr. Wickii Vigneswaran , thoracic surgeon

Testicular Mesothelioma Symptoms

Testicular mesothelioma occurs in the lining of the testes and is the rarest form of mesothelioma. The main signs are a lump or swollen testes.

Signs and Symptoms of Testicular Mesothelioma

  • Fluid buildup in the scrotum (hydrocele)
  • Inguinal hernia
  • Lump in the scrotum
  • Spermatocele (cyst in the epididymis)
  • Swollen testes
  • Testicular pain

Other early symptoms of testicular mesothelioma include pain similar to a groin injury. Sometimes, these symptoms are mistaken for an infection of the testes.

Managing Mesothelioma Symptoms 

Palliative care and supportive care are approaches to symptom management that can begin at diagnosis and support you throughout curative treatments like surgery, chemotherapy or radiation. The goal is to maintain your quality of life while you pursue treatment. A comprehensive symptom management plan addresses physical discomfort and supports overall health, including nutrition, exercise and mental well-being.

Common Treatments to Manage Mesothelioma Symptoms

  • Complementary therapies: Massage, acupuncture, meditation, gentle yoga and cognitive behavioral techniques can reduce pain, anxiety and stress.
  • Fluid drainage procedures: Techniques like thoracentesis and paracentesis remove fluid buildup in the lungs or abdomen to relieve pressure and improve breathing.
  • Pain medication: Mild pain may be managed with over-the-counter drugs like acetaminophen. More severe pain often requires prescription opioids such as morphine or oxycodone.
  • Physical and occupational therapy: These therapies enhance strength, mobility and help patients manage daily activities.
  • Radiation therapy: Radiation can reduce tumor size and alleviate pain, particularly for nerve-related or chest wall discomfort.
  • Respiratory therapy: Breathing exercises and supplemental oxygen ease shortness of breath and improve lung function.

Counseling and support groups tailored for mesothelioma patients address anxiety, depression and social challenges linked to this rare and aggressive cancer. Taking an active role in symptom management can enhance comfort, help patients maintain independence longer and improve overall outlook.

Managing Symptoms as Mesothelioma Progresses

As mesothelioma progresses, symptom intensity increases. In intermediate and advanced stages, your care team may include pain specialists, nutritionists or respiratory therapists. Palliative care can continue throughout treatment, including multimodal therapy.

Treatments like tumor-removing surgery, chemo and immunotherapy can reduce tumors and relieve symptoms. Surgery may ease pressure-related pain, while chemo and immunotherapy can help slow cancer growth and control symptoms.

When curative treatment becomes less effective or a decision is made to stop more aggressive treatments, the focus shifts to staying as comfortable and independent as possible. Hospice care may become part of the conversation in late-stage mesothelioma. Palliative care, supportive care and hospice care often work together, each addressing a different part of comfort and quality of life as symptoms become more severe.

Expert Insight

“Palliative care is becoming a bigger topic these days, especially in a terminal diagnosis, especially cancer. It is comfort care, but it’s pain management, and it’s something that a patient can do and start from the beginning. I recommended it because I just don’t see a need for a patient to suffer or be in pain when they don’t have to be.”

Amy pelegrin
Amy Pelegrin , hospice care director at The Mesothelioma Center

Managing Symptoms of Pericardial and Testicular Mesothelioma

Symptom management for pericardial and testicular mesothelioma can differ from pleural and peritoneal mesothelioma because these types are much rarer. Fewer cases exist to guide standard treatment approaches.

Palliative care and supportive care can be tailored to your specific symptoms. A specialist familiar with these rare types can help guide treatment decisions and symptom management, including care for heart-related discomfort from pericardial mesothelioma or recovery after testicular mesothelioma surgery.

Common Questions About Mesothelioma Symptoms

When do mesothelioma symptoms appear?

Mesothelioma symptoms tend to present between 20 and 60 years after asbestos exposure. This delay is known as the latency period. Asbestos exposure, age, and health can affect the latency period.

 

Can you have mesothelioma without symptoms?

Yes, you may have mesothelioma without any symptoms. Many mesothelioma symptoms are mild and resemble the flu or a stomach virus. Most only appear decades after asbestos exposure. Doctors may misdiagnose this rare cancer as other illnesses. This can delay your mesothelioma diagnosis.

Can mesothelioma symptoms come on suddenly?

Yes, some mesothelioma symptoms may occur suddenly. Some patients have no symptoms until the cancer spreads to other organs. The cancer’s location determines the type and severity of symptoms you may have.

Do mesothelioma symptoms progress quickly?

It varies. Mesothelioma symptoms usually develop slowly over many years following asbestos exposure. Early signs can be mild or nonexistent, making them difficult to detect. However, as the cancer advances into later stages, symptoms tend to worsen more quickly and become more severe.

What is the most common symptom of mesothelioma?

Pleural effusion, or fluid buildup around the lungs, is the most frequently reported symptom of pleural mesothelioma, the most common form of the disease. According to the National Institutes of Health, up to 90% of mesothelioma patients experience pleural effusion. It can cause shortness of breath, chest pressure and persistent coughing.

When should I see a mesothelioma specialist?

See a mesothelioma specialist if you have a history of asbestos exposure and notice chest or abdominal pain, unexplained weight loss, persistent cough or shortness of breath. These symptoms don’t always mean you have mesothelioma, but a specialist can recommend the appropriate tests to determine the cause. Bring details about when your symptoms started and how they’ve changed. That information can help your doctor determine the next steps.
