benign mesothelioma pathology outlines - What You Need To Know

benign mesothelioma pathology outlines - This pathology outline for mesothelioma is focused on providing you with detailed information about the disease. Mesothelioma, also know as a absestos cancer, is a rare, aggressive, and deadly form of cancer that develops in the thin layer of the membrane covering internal organs such as the lungs, abdomen, heart, and tunica vaginalis.


Mesothelioma of the pleura is the common.

Epidmilogy

Since the mid 20th century, mesothelioma incidence has been steadily rising. A WHO recorded mortality database between the years 1994 and 2008 gave an age-adjust mortality rate of approximately 4.9 per million, male to female ratio of 3.6.1 and a mean age at death of 70 years. The annual incidence of mesothelioma recorded in the United States is estimated to be approximately 3300 cases per year, although the number is steadily subsiding due to control of absestos exposure. Male diagnoses in Australia dominate, and more than 75 % of the newly diagnosed patients are aged 65 years or older.

Etiology

Absestos exposure is the primary culprit as it has an etiogical fraction that is higher than 80 % prolonged absestos exposure has a prolonged latency period. Peritoneal mesothelioma has a significantly shorter latency compared to pleural mesothelioma. Longer latency periods are evident in more recent diagnosis.

The role of the crocidolite is well established, it accounts for approximantely 95 % of total asbestos used in various applications and is a more potent carcinogen compared to chrysotile of the serpentine form.
