Shortness of breath is one of the most common symptoms of pleural mesothelioma. It is caused by fluid buildup, tissue thickening, and tumor intrusion. Palliative procedures and lifestyle changes can provide relief.
What Is Shortness of Breath?
Also known as dyspnea or breathlessness, shortness of breath is common in patients diagnosed with pleural mesothelioma.[1] It is a distressing, uncomfortable symptom that occurs even in the early stages of the cancer.
Patients experience dyspnea in several ways:
- Difficulty breathing
- Tightness in the chest
- Coughing or wheezing
- Rapid and shallow breaths
- Feeling suffocated
- Heart palpitations
- Breathlessness
Is Shortness of Breath an Early Warning Sign of Mesothelioma?
Breathlessness is one of the most common symptoms of pleural mesothelioma. It often results from the buildup of fluid around the lungs. Shortness of breath is often an early warning sign.
Shortness of breath can result from several non-cancerous conditions, like low blood pressure, pulmonary embolism, heart disease, and asthma. It’s important to note any other symptoms that might indicate mesothelioma, especially if you might have been exposed to asbestos.
What Causes Shortness of Breath?
Due to how this cancer infiltrates the lining of the lung, it limits how much the lungs can expand. There is also fluid buildup around the lungs, pain, treatment side effects, and other causes of dyspnea in mesothelioma:
Pleural Thickening
The pleural tissue, where the primary tumors grow, often thickens in patients with mesothelioma. The normal role of the pleura is to allow the lungs to expand easily and painlessly.
When it thickens, lung expansion becomes more difficult, which can trigger shortness of breath and related symptoms.
Pleural Effusion
Another cause of shortness of breath is a typical complication of pleural mesothelioma: a buildup of fluid between the two pleural layers. As with pleural thickening, effusion prevents the full expansion of the lungs, and therefore, less oxygen is available when breathing.
Pain
Pain is another common symptom of mesothelioma. The pain may result from pleural effusion or thickening, but it may also be caused by treatments or the tumors pushing against tissues and organs. When pain in the chest makes it difficult to take full breaths, this can lead to dyspnea.
Treatment
In some cases, the treatment for mesothelioma may cause or worsen shortness of breath in the short term. Surgery to remove significant tissue from the chest cavity, for instance, may worsen breathing.
One study also found that the use of radiation therapy in the chest makes shortness of breath worse in patients with mesothelioma or lung cancer due to long-term scarring effects as well as injury to the lung tissue itself.[2]
Other Causes
The tumors can be large enough to restrict breathing and lung expansion, leading to shortness of breath. Tissues in the chest cavity, including the diaphragm, may also stiffen with pleural mesothelioma, making breathing difficult. Mesothelioma patients may develop respiratory infections, such as pneumonia, which causes shortness of breath.
Is Shortness of Breath a Symptom of Advanced Mesothelioma?
Advanced, stage 4 mesothelioma causes various symptoms. Many of the early-stage symptoms get worse as the cancer advances. Shortness of breath is a common symptom in advanced mesothelioma and can cause significant discomfort and disability. This is why palliative care is so important.
Shortness of Breath in Other Types of Mesothelioma
Shortness of breath is most common in pleural mesothelioma, but it may also occur in the other types:
- Peritoneal. When the cancer in the abdomen intrudes into the diaphragm or causes fluid buildup that puts pressure on it, shortness of breath may result. Cytoreductive surgery and draining of the fluid can help.
- Pericardial. Although rare, mesothelioma can develop around the heart. Because it is so close to the lungs, this can cause pressure and shortness of breath. Fluid can be drained from the pericardium to provide relief.
Palliative Treatments for Shortness of Breath
Shortness of breath has a significant negative impact on quality of life. It limits mobility and activity and causes anxiety and fear.
Palliative procedures that improve breathing are essential for restoring some activity level and reducing distress, although they do not directly treat the cancer:[3]
- Thoracentesis. This procedure drains fluid from the chest cavity to relieve pleural effusion.
- Pleurodesis. This is a surgical procedure that typically uses mechanical methods and instillation of a chemical into the pleural space to create inflammation that makes this space “scar close”. Talc is the most common chemical used. In the best-case scenario, this procedure prohibits fluid from re-accumulating. Sometimes there are pockets of fluid that fill back up. In other cases, it can work for a period of time but ultimately fail, causing all the fluid to again re-accumulate. The duration it is successful is variable and dependent on several factors.
- Pleurectomy/Decortication. This is a surgical procedure used both for treatment of the cancer and for palliation. Surgery used to treat the cancer by removing tumors can help relieve symptoms. As a palliative measure, removing part of the pleura can help patients breathe better.
- Indwelling pleural catheter. Another solution to keep draining the fluid is to install a pleural catheter. The patient keeps the catheter in place and manages the drain, sometimes with the assistance of a home health aide.
- Morphine. Some studies have found that low-dose, sustained-release morphine can relieve some breathlessness.
Management Strategies and Home Remedies for Shortness of Breath
Studies of patients with mesothelioma and other illnesses that cause shortness of breath show that non-surgical and non-pharmacological strategies can provide some relief. These are particularly useful for patients who cannot undergo surgery or do not want to take medications.
If you are struggling with breathlessness and finding relief, talk to your medical team. They can provide tips and also specialists to help you utilize some of these strategies and lifestyle practices:[4][5]
- Using a fan. Several studies indicate that the simple act of sitting in front of a fan that provides a gentle breeze can relieve breathing difficulties. This is so simple and risk-free that it is often used as the first strategy for managing shortness of breath.
- Relaxation techniques. Breathlessness may trigger anxiety and stress, and these, in turn, can make the symptoms worse. Try any strategy that relaxes and eases stress, such as meditation, breathing exercises, guided imagery, and gentle yoga.
- Breath control training. Respiratory specialists can help you learn how to manage your breathing better through control and breath re-training exercises. For instance, pursed-lip breathing is a strategy that helps you slow down and breathe more deeply and effectively.
- Lifestyle changes. Anything you can do to reduce stress will be helpful, as will certain changes that make breathing easier. When eating, go slowly and eat smaller meals. For sleeping, try using pillows to find a position that makes it easier to breathe. Sleeping on your back can worsen shortness of breath.
Dyspnea is a very common but serious side effect of living with pleural mesothelioma. It is uncomfortable, distressing, and limiting. Talk to your doctor to get ideas and referrals to specialists for managing this symptom.
