Key Takeaways
- Mesothelioma and blood clots are connected because cancer and certain cancer treatments can increase the risk of abnormal blood clotting.
- Mesothelioma patients may develop deep vein thrombosis (DVT) or pulmonary embolism (PE).
- Warning signs of blood clots include leg swelling, unexplained pain, sudden shortness of breath, and chest discomfort.
- A pulmonary embolism is a medical emergency that requires immediate attention.
- Doctors may use blood-thinning medications, imaging tests, and other treatments to manage blood clots in mesothelioma patients.
Mesothelioma is a rare cancer caused by asbestos exposure that affects the lining of the lungs, abdomen, or other organs. While the disease is often linked to breathing problems, chest pain, and fatigue, it can also increase the risk of serious blood clots. The connection between mesothelioma and blood clots is important because cancer can affect how blood flows and clots inside the body. Some patients may develop clots in their legs or lungs, which can lead to dangerous complications if left untreated.
Understanding why mesothelioma blood clots develop, how to recognize warning signs, and what treatments are available can help patients and families make informed decisions about their care.
Why Mesothelioma Increases Blood Clot Risk
Cancer can change the body’s normal blood-clotting process. Certain cancers cause the body to release substances that make blood more likely to clot.
Mesothelioma patients may also face other factors that increase their risk of blood clots.
These include:
- Reduced movement: Pain, fatigue, or hospitalization may cause patients to spend more time sitting or lying down.
- Cancer treatments: Some chemotherapy treatments and major surgeries can increase clotting risks.
- Inflammation: Cancer-related inflammation can affect how blood clots form.
- Hospital stays: Long periods of limited movement may slow blood flow.
- Other medical conditions: Previous blood clots, certain heart conditions, and other health problems can add to the risk.
Not every person with mesothelioma will develop blood clots. However, recognizing these risk factors can help patients discuss prevention with their healthcare team.
Types of Mesothelioma Blood Clots
Mesothelioma blood clots may develop in different parts of the body. Two of the most serious conditions are deep vein thrombosis and pulmonary embolism.
Deep Vein Thrombosis (DVT)
Deep vein thrombosis occurs when a blood clot forms in a deep vein, usually in the leg.
Common symptoms include:
- Swelling in one leg
- Pain or tenderness in the calf or thigh
- Warmth around the affected area
- Redness or changes in skin color
Some patients develop DVT without noticeable symptoms.
A major concern is that part of the clot can break loose and travel through the bloodstream to the lungs.
Pulmonary Embolism (PE)
A pulmonary embolism occurs when a blood clot blocks an artery in the lungs. It often develops when a clot travels from a deep vein in the leg.
Warning signs may include:
- Sudden shortness of breath
- Sharp chest pain, especially when breathing deeply
- A rapid heartbeat
- Coughing up blood
- Dizziness or fainting
A pulmonary embolism is a medical emergency. Anyone experiencing sudden breathing problems, chest pain, fainting, or other signs of a pulmonary embolism should seek emergency medical care immediately.
Can Mesothelioma Symptoms Hide Blood Clots?
One challenge involving mesothelioma and blood clots is that some symptoms can overlap.
For example, pleural mesothelioma often causes shortness of breath and chest discomfort. These symptoms can also occur when a blood clot develops in the lungs.
Because of this overlap, patients may have difficulty recognizing when a new complication is developing.
Warning signs that deserve immediate attention include sudden breathing changes, new chest pain, or unexplained swelling in one leg.
Patients should not assume that new or worsening symptoms are simply part of their mesothelioma diagnosis.
How Doctors Diagnose Blood Clots
Doctors use several tests to determine whether a patient has developed a blood clot.
The tests selected depend on the patient’s symptoms, medical history, and overall condition.
Common diagnostic methods include:
- Ultrasound: Uses sound waves to check for blood clots in the deep veins, usually in the legs.
- CT Pulmonary Angiography: Uses a special CT scan with contrast dye to look for blood clots in the lung arteries.
- Blood Tests: A D-dimer test measures substances released when blood clots break down. However, cancer itself can raise D-dimer levels, so the test cannot confirm a clot on its own.
- Other Imaging Tests: A ventilation-perfusion scan may be used when CT pulmonary angiography is not appropriate.
Early diagnosis is important because untreated blood clots can cause serious complications.
Treating Mesothelioma Blood Clots
Treatment for mesothelioma blood clots usually focuses on preventing existing clots from growing and reducing the chance of new clots forming.
Doctors may recommend blood-thinning medications, also called anticoagulants.
These medications help prevent additional clotting while the body gradually breaks down existing clots.
Common treatment options include:
- Anticoagulant medications: Certain oral medications or injections may be used to treat cancer-associated blood clots.
- Hospital monitoring: Patients with serious clots may need hospital care and close monitoring.
- Emergency procedures: In severe cases, doctors may use clot-dissolving medications or procedures to remove a dangerous clot.
Treatment decisions depend on the patient’s cancer, bleeding risk, kidney function, other medications, and overall health.
Some patients require anticoagulant treatment for several months or longer, especially when their cancer remains active.
Can Mesothelioma Blood Clots Be Prevented?
Although not every blood clot can be prevented, certain steps may help reduce the risk.
Patients should discuss prevention with their healthcare team, particularly during cancer treatment or after surgery.
Depending on their condition, doctors may recommend:
- Staying physically active when medically appropriate
- Moving their legs regularly during long periods of sitting
- Following medical advice after surgery or hospitalization
- Drinking enough fluids unless otherwise restricted
- Taking prescribed blood-thinning medications when recommended
- Reporting new swelling, leg pain, or breathing problems promptly
Patients should never begin taking blood-thinning medications without medical guidance because these drugs can cause serious bleeding.
Why Blood Clot Awareness Matters for Mesothelioma Patients
Mesothelioma and blood clots can create additional health challenges for patients already managing a serious cancer diagnosis.
Blood clots may interrupt cancer treatment, require hospitalization, or increase the risk of dangerous complications.
Recognizing symptoms early and communicating changes to a healthcare team can help patients receive appropriate testing and treatment.
Patients and caregivers should remain aware of new symptoms, particularly sudden breathing difficulties, chest pain, or swelling in one leg.

Frequently Asked Questions
Can mesothelioma cause blood clots?
Yes. Mesothelioma can increase the risk of blood clots because cancer may affect the body’s clotting process. Surgery, chemotherapy, and reduced movement can also contribute to the risk.
What are the symptoms of mesothelioma blood clots?
Symptoms may include swelling or pain in one leg, warmth around the affected area, sudden shortness of breath, chest pain, and a rapid heartbeat. Sudden breathing problems or chest pain require emergency medical attention.
Are blood clots common in mesothelioma patients?
People with cancer have an increased risk of blood clots, including those diagnosed with mesothelioma. However, individual risk depends on factors such as cancer stage, treatment, medical history, and mobility.
How are blood clots treated in mesothelioma patients?
Doctors commonly prescribe anticoagulant medications to prevent clots from growing and reduce the risk of new clots. Treatment depends on the patient’s condition, bleeding risk, and cancer treatment plan.
Can a blood clot affect mesothelioma treatment?
Yes. A blood clot may require additional medications, hospital care, or changes to a patient’s treatment schedule. Healthcare teams consider clotting and bleeding risks when planning cancer treatment.
