Key Takeaways
- Mesothelioma affects approximately 3,000 people per year in the United States. While it impacts individuals across all demographics, clear trends emerge by age, gender, and race.
- Age: The median age of diagnosis is 72 years, driven by mesothelioma’s latency period of 13 to 70 years. However, younger individuals can be affected — cases have been documented in patients as young as 17 years old.
- Gender: Men are diagnosed at significantly higher rates than women because of historically male-dominated occupational asbestos exposure. However, women have been recognized to have a longer survival rate, potentially linked to higher estrogen levels.
- Race and ethnicity: White individuals have the highest mesothelioma diagnosis rate, followed by Hispanic, Asian and Pacific Islander, and Black populations. Black patients tend to have lower survival rates, which researchers attribute to delayed access to treatment, insurance disparities, and later symptom onset.
- Demographic patterns reflect exposure history — not biological susceptibility. Occupational exposure, environmental exposure, secondary exposure through family members, and genetics all play a role.
In the United States alone, there is an average of 3,000 cases of mesothelioma per year. Mesothelioma is a rare form of cancer that attacks the tissue lining of vital organs. Although mesothelioma impacts individuals of all demographics, there can be trends found in specific areas. It is important to mention that there are other supporting variables to the impacts of the diagnosis such as environmental exposure, occupational exposure, and genetics. These other variables will further impact the prognosis for mesothelioma and treatment options.
Types of Mesothelioma
There are four organs where the mesothelioma can begin, we will describe them from most prevalent to least prevalent.
- Pleural Mesothelioma: Tissue lining the lungs
- Peritoneal Mesothelioma: Tissue lining the abdomen
- Pericardial Mesothelioma: Tissue lining the heart
- Testicular Mesothelioma: Tissue lining the testicles
Age Demographics and Mesothelioma
According to the National Library of Medicine, it has been recognized that the long latency period of mesothelioma creates a median age of 72 years. The latency period is identified to occur within 13-70 years (C. Pérez-Guzmán et al.).While most cases involve patients nearer to this age, is it not impossible for younger individuals to become diagnosed. There was a reported case of a 17-year-old boy with symptoms of “moderate dyspnea, cough, right-sided pleuritic chest pain, fever, and headache” (C. Pérez-Guzmán et al.). He was later diagnosed with pleural mesothelioma. The treatments for this disease additionally vary in age. It appears that younger individuals who are diagnosed with the disease are more likely able to undergo surgery as opposed to patients of older ages.
Gender Demographics and Mesothelioma
Men are historically recognized to have higher rates of diagnoses than women. Occupational exposure is responsible for this occurrence. According to the National Library of Medicine, it can also be recognized that women “were traditionally at risk of exposure to asbestos if their spouses worked…and brought home asbestos on their clothing”(Freudenberger and Shah). Additionally, women have been recognized to have a lengthier survival rate. It is believed that the increased estrogen levels found in female patients aid in the survival time. Alternative variables can include age, histology, and general health.
Race & Ethnicity
White individuals are more likely to be diagnosed with mesothelioma than their counterparts in order: Hispanic, Asian & Pacific Islander, Black, and with little to no diagnosis in American Indian & Alaska Native. In addition to this, Whites are also recognized to have a longer survival rate compared to their Black and Asian & Pacific Islander counterparts. External variables that are believed to impact the lower survival rate and later diagnosis in Black patients are delayed access to treatment and the “lack of insurance amongst this population, or differences in the onset of symptoms” (Freudenberger and Shah).

Frequently Asked Questions
What is the average age of mesothelioma diagnosis?
The median age of mesothelioma diagnosis is 72 years. This is driven by the disease’s long latency period — it can take anywhere from 13 to 70 years after asbestos exposure for mesothelioma to develop. Most patients were exposed to asbestos decades ago during their working years and are only now receiving a diagnosis. However, mesothelioma is not exclusively an older person’s disease — cases have been documented in patients as young as 17.
Does age affect treatment options for mesothelioma?
Yes. Younger patients who are diagnosed with mesothelioma are generally more likely to be candidates for aggressive treatments including surgery, because they tend to be in better overall physical condition. Older patients may not be physically able to undergo major surgical procedures and are more likely to receive chemotherapy, radiation, immunotherapy, or palliative care. However, treatment decisions are always based on the individual patient’s health, stage of cancer, and cell subtype — not age alone.
Why are men diagnosed with mesothelioma more often than women?
Men are diagnosed at higher rates because occupational asbestos exposure occurred predominantly in male-dominated industries — including shipbuilding, steelworking, construction, insulation, and firefighting. The disparity reflects exposure history, not biological susceptibility. When exposed to the same amounts of asbestos, men and women are equally at risk. Women who develop mesothelioma were often exposed through secondary pathways — laundering contaminated work clothes, hugging family members who worked with asbestos, or living near industrial facilities.
Why do women tend to have a longer mesothelioma survival rate?
Research suggests that higher estrogen levels in female patients may contribute to longer survival times. However, other factors also play a role, including age at diagnosis, the histological subtype of the cancer (epithelioid tends to have a better prognosis), and overall general health at the time of diagnosis. More research is needed to fully understand the gender-based survival difference.
How does race and ethnicity affect mesothelioma diagnosis and survival?
Mesothelioma diagnosis rates vary by race and ethnicity. White individuals have the highest incidence rate, followed by Hispanic, Asian and Pacific Islander, and Black populations. These differences are believed to reflect historical patterns of occupational exposure across different communities rather than biological factors.
Survival rates also differ — Black patients tend to have lower survival rates compared to White and Asian and Pacific Islander patients. Researchers attribute this disparity to several factors, including delayed access to treatment, lack of insurance coverage, and differences in the timing of symptom onset and diagnosis.
Can young people get mesothelioma?
Yes, although it is rare. While the vast majority of mesothelioma cases occur in adults aged 65 and older, the disease can affect younger individuals. A documented case involved a 17-year-old boy who presented with shortness of breath, cough, chest pain, fever, and headache and was later diagnosed with pleural mesothelioma. Young patients may have been exposed to asbestos through environmental contact, secondary exposure from a parent’s work clothes, or — in very rare cases — genetic predisposition (such as BAP1 mutations).
What should I do if I’ve been diagnosed with mesothelioma?
If you or a loved one has been diagnosed with mesothelioma or another asbestos-related disease — regardless of age, gender, or background — understanding your treatment options and legal rights is a critical first step. Call (800) 505-6000 or fill out our contact form for a free consultation.
