Mesothelioma Life Expectancy


Mesothelioma Life Expectancy

Currently no cure for mesothelioma exists and the American Cancer Society explains that patients generally have a short average life expectancy of four to 18 months after diagnosis. Only 10% of mesothelioma patients survive more than five years after initial diagnosis. Since its recognition as a lethal form of cancer that develops after asbestos exposure, doctors and scientists have struggled to identify a course of treatment that can improve the prognosis for patients today.

Nevertheless, efforts today still generally focus on prolonging the overall quality of life and life expectancy of these patients instead of finding a cure. Among these treatments are experimental and alternative therapies meant to relieve symptoms and improve a patient’s ability to lead a normal life.

Factors that Affect Life Expectancy

Malignant mesothelioma, like other cancers, is described in four stages. Early detection has proven significant in leading to prolonged life expectancy.


Latency Period

Unlike other forms of cancer, symptoms of mesothelioma may not be seen for decades after initial exposure. This extended period of latency allows the cancer to develop and spread even before it is diagnosed. As a result of this late diagnosis, many patients can only receive palliative care to alleviate their pain, rather than fight the onset of the disease itself. When diagnosed in the later stages, mesothelioma does not respond to treatments as well and patients frequently do not possess the strength to undergo intensive surgery or therapies. This latency and subsequent pattern of treating symptoms rather than the disease itself gives mesothelioma an extremely poor life expectancy.

Patient Age

Statistics show that the average age of mesothelioma patients is 60, with the disease affecting men over the age of 55 in 75% of all cases. Because many older patients might suffer from other illnesses that can affect the healing process, the immune systems of these individuals might not be able to fight this condition as well. Furthermore, younger patients are typically able to undergo more aggressive treatments, whereas older patients, who generally develop mesothelioma, may not be able to handle the stress of serious treatments.


Since many cases of mesothelioma are connected to occupational asbestos exposure, males are the predominant gender affected by this cancer. While fewer females are affected, and consequently less involved in clinical trials, for reasons unknown, women seem to have a better prognosis regarding life expectancy.

While all forms of mesothelioma are lethal, how much we know about each form of the disease impacts our ability to treat it. Pleural mesothelioma, which affects the tissue surrounding the lungs, is the most common form of the cancer. As a result, far more research has been done on this particular form of the disease, allowing doctors to develop and test more treatment options.

Other forms of the disease, including peritoneal and pericardial mesothelioma, remain far more difficult to treat because doctors do not have the opportunity to analyze the effectiveness of previous treatments as often. Furthermore, extremely rare forms of this disease, like testicular mesothelioma, carry an even poorer prognosis and life expectancy because doctors have had so few opportunities to develop and test courses of treatment.


Malignant mesothelioma can be broken down into three histologic subtypes – epithelioid, sarcomatoid, and biphasic (mixed).


Smoking remains one of the biggest contributors to a short life expectancy in mesothelioma patients. Although smoking does not directly cause mesothelioma, it can aggravate the condition and compromise a patient’s overall health. Particularly for patients who suffer from pleural mesothelioma, smoking can greatly decrease life expectancy in even healthy individuals, while also impacting their quality of life. As the only controllable aspect affecting the life expectancy of mesothelioma patients, the detrimental impact of this lifestyle choice deserves attention.

Prolonging Life Expectancy

Scientists and researchers are constantly studying and developing new ways to improve the quality of life and life expectancy in patients with all types of cancer, including mesothelioma. Clinical trials that test the efficacy of new drugs and treatment methods now occur frequently, giving patients hope. However, in the case of mesothelioma, the most important frontier will be in the field of diagnosis. As an asymptomatic disease, overcoming the latency period will go a long way into treating the disease and increasing a patient's life expectancy.

While some patients may elect to undergo more high intensity treatments in order to kill off cancerous cells, limitations like age, health and cancer stage often make this impossible. Surgery, chemotherapy and radiation are some of the more common forms of treatment used today, although doctors hope to develop more advanced procedures to help in the treatment of this disease which carries such a poor life expectancy.

Other actions in the cancer battle may include getting a second opinion, undergoing alternative treatments, being a part of a clinical trial, improving nutrition, or taking immune system enhancers.

A second medical opinion is always a good idea as mesothelioma and its stages are commonly misdiagnosed. A patient may be told they are dealing with stage III mesothelioma by one doctor and seek a second opinion only to find they really have stage II cancer. This misdiagnosis can make a big difference as far as treatment options and life expectancy.

Alternative Therapies

While they are not medically recognized as cures for cancers, especially one as aggressive as mesothelioma, alternative treatments have been very popular among patients seeking help outside of traditional medicine. Numerous patients suffering from mesothelioma have benefitted from options such as acupuncture, meditation and holistic medicines, to name a few. While these therapies are symptom-reducing measures, not curative treatments, they have been receiving more attention lately as part of a multimodal approach to combating mesothelioma. With a sea of alternative therapies including manual healing options and those concerning the mind, body and spirit available, patients are sure to find a method that they are comfortable with and one that might just work for them.

Clinical Trials

Clinical trials are always recruiting volunteers, and researchers are constantly testing new medicines and treatment approaches with the hope of one day finding a cure for mesothelioma. These trials allow patients to take advantage of new treatments that may extend survival; however, they do not come without risk.


Nutrition has a large impact on health in general. More importantly, if an individual is diagnosed with mesothelioma, it is important to factor in a healthy balance of beneficial foods high in antioxidants, minerals and proteins. Eating at least five servings of fruits and veggies a day is recommended for those suffering from cancer. These foods are high in antioxidants and can boost the immune system making the body healthier and more able to fight diseases.

Immune system enhancers boost the immune system making the body stronger. Treatments such as immunotherapy rejuvenate the immune system by seeking to repair faulty aspects of the system that are not working up to par.

Other Life Expectancy Factors

While the above seem to be the main factors involved in predicting a patient’s life expectancy, other factors have been linked to longer survival times. These factors include:

Patients suffering from mesothelioma are served a daunting sentence. They may be scared and anxious for what the future has to offer. While typical outcomes do follow a discouraging trail, all the new discoveries and medicines, along with scientists, doctors and researchers dedicated to finding a cure, make the future of mesothelioma diagnosis and treatment promising.
