There are three categories of mesothelioma cancer cells:
Malignant mesothelioma is generally divided into three histological categories, or types of cells: epithelioid, sarcomatoid and biphasic mesothelioma. Within each of these mesothelioma cancer cell types, subtypes exist. Many mesothelioma patients display more than one cell type.
The diagnosis of mesothelioma cannot be specifically by lung x-rays or other types of imaging, because many different types of cancer can be present in the lungs. The images show only that a tumor may be present, but does not provide an indication of whether the tumor is mesothelioma. A biopsy must be performed where the mesothelioma cancer cell types are used to distinguish mesothelioma from other types of cancer, such as lung cancer.
Epithelioid Mesothelioma Cancer
Epithelioid mesothelioma is the most common cell type, constituting approximately 50% to 70% of all malignant mesothelioma. These cells are relatively uniform in shape and have a tubular pattern with a distinct cell nucleus. The individual cells are shaped like cubes or multi-sided boxes.
Because of the similarity between adenocarcinoma and mesothelioma cancer cells, they are often confused and mesothelioma can be misdiagnosed. Inspection of the cancer cells under high-powered microscopes and identification of unique characteristics of the chemical properties of the cells can help make the proper diagnosis.
Sarcomatoid Mesothelioma Cancer
Sarcomatoid mesothelioma is the least common type of mesothelioma cancer cell and accounts for approximately 10% to 15% of malignant mesothelioma. These cells typically have more of an oval, irregular shape and the nucleus of each cell is not as visible with a microscope as the epithelioid mesothelioma cancer cells. Because of the similarity of appearance, the sarcomatoid cancer cells can also easily be confused with the more typical sarcoma cancer cells. Learn more about sarcomatoid mesothelioma cancer.
Biphasic Mesothelioma Cancer
Approximately 20% to 40% of the mesothelioma cancer cells fall into the biphasic category, which is combination of the sarcomatoid and epithelioid types. The biphasic type can occur with the two types of cells intermixed continuously throughout the tumor, or with them in specific groupings. Transitional areas between the two cell types are often present. Learn more about biphasic mesothelioma cancer.
Those dealing with asbestos and mesothelioma face a number of challenges, including the tremendous costs of treatment. If you were unknowingly exposed to harmful levels of asbestos, you have legal rights and there is help available for you.
Deciding which law firm to represent you and your case is very important. Choosing the right law firm will also be important to your settlement. You are entitled to an experienced mesothelioma law firm who has a track record of success in asbestos lawsuits.
It is not uncommon for there to be 10-20 parties that are named in a asbestos lawsuit that are located across the United States. For example, a worker in California may have been exposed to asbestos from asbestos products shipped from Libby, Montana or from an iron ore plant in St. Paul Minnesota. This is why it is very important to obtain an experienced asbestos mesothelioma law firm that knows all of the companies in each state who have responsibility for your asbestos exposure.
If you are a grieving family member or executor of the will of a person who has died from asbestos-related disease or mesothelioma, you may be eligible to file a claim as well. |
