Key Facts On Mesothelioma Locations

  • Between 2,500 and 3,200 cases of mesothelioma are diagnosed annually in the United States.
  • Pleural mesothelioma accounts for approximately 75 percent of cases, and peritoneal accounts for 10 to 20 percent.
  • Only 1 percent of cases arise from the heart or testicles. However, incidence varies from year to year.
  • From 2003-2008, nearly 90 percent of cases were pleural, and 9 percent were peritoneal.

Four Types of Mesothelioma by Location

The type of mesothelioma you are diagnosed with is named after the place it developed. For example, when the cancer forms in the pleural lining around the lungs, it is called pleural mesothelioma.

Pericardial Mesothelioma

  • Location: Exterior lining of the heart
  • Symptoms: Irregular heartbeat, chest pain, difficulty breathing and cough
  • Prognosis: 50 percent live for 6 months. Pericardial mesothelioma is extremely rare. Around 200 cases are reported in medical literature. Surgery helps some patients live for years beyond the average six-month survival rate.

Peritoneal Mesothelioma

  • Location: Lining of the abdomen
  • Symptoms: Abdominal pain and distention, bloating and bowel changes
  • Prognosis: 50 percent live 5+ years after surgery with HIPEC. Even though less research has been conducted on this type compared to pleural, the prognosis for peritoneal mesothelioma is better. Around 40 percent of peritoneal patients qualify for surgery with heated chemotherapy (HIPEC). Half of patients who undergo this treatment live longer than five years. Peritoneal mesothelioma occurs more commonly in women than men. The peritoneal type accounts for 7 percent of mesothelioma cases in men and 17 percent of mesothelioma cases in women.

Pleural Mesothelioma

  • Location: Lining of the lungs
  • Symptoms: Breathlessness, chest pain, fever and fatigue
  • Prognosis: 3+ years at stage 1 vs. 12 months at stage 4
    Because it is the most common type of mesothelioma, there’s plenty of research conducted on the pleural form. Most patients qualify for chemotherapy, radiation therapy and immunotherapy, which can add months or years to life expectancy. About 20 percent qualify for surgery that has the potential to help them live three or more years beyond the average 12-month survival rate.

Testicular Mesothelioma

  • Location: Testicles
  • Symptoms: Scrotal swelling, painless testicular lumps
  • Prognosis: 2 years
    Testicular mesothelioma develops in the tunica vaginalis, the lining of the testes. Less than 100 cases are reported in medical literature. Treatment involves surgery and chemotherapy, which helps people live more than two years on average.
