Another kind of a rare mesothelioma, which is asbestos linked cancer, is abdominal mesothelioma, also referred to as peritoneal mesothelioma. The name gives the description that abdominal mesothelioma is a variation of cancer that affects the abdominal cavity tissues. The most common public for abdominal mesothelioma to affect are men aged from 50 to 70, leaving only one fifth of total abdominal mesothelioma cases to women.
Abdominal mesothelioma is the second most common kind of mesothelioma after the Pleural Mesothelioma.
There are a lot of organs located in the abdomen that are covered by a membrane, the peritoneum, consisting of mesothelial cells. When peritoneal mesothelioma occurs it creates a tumor covering this membrane. This cause is the only one known in the U.S., happening after the exposure to asbestos took place. The trouble is that a long time after the asbestos exposure may pass before the disease gives any signals. Approximately one fifth of all mesothelioma cases are devoted to peritoneal mesotheliomas.
Peritoneal mesothelioma can have benign or malignant varieties, as well as pleural mesothelioma. Further discussion refers only to malignant peritoneal mesothelioma.
X-ray or CT scan are initial analyses for peritoneal mesothelioma diagnosing. In case the peritoneal mesothelioma possibility is found out the doctor may prescribe exploratory surgery and a biopsy for further diagnosing. Peritoneal mesothelioma tumors are preferably attempted to be removed by surgery if it is possible. Though, the aim of the majority of treatment attempts is to make the patient's life quality as high and long as it is possible due to the fact that the effective treatment cannot be carried out in cases of highly advanced peritoneal mesothelioma which are the majority of this disease. The outside party often has a financial accountability to the peritoneal mesothelioma patient due to the direct link of the disease to asbestos exposure. It means that the party mentioned above is to cover any peritoneal mesothelioma costs, such as lost wage, medical bills and punitive fees.
It is possible to diagnose mesothelioma in advance, before any symptoms declare themselves, but it mostly happens by coincidence. In this way, mesothelioma can be found out by preoperational or check-up abdominal x-ray.
The symptoms that can help to find out mesothelioma are the following: abdominal pains, weakness, weight reduction, appetite loss, nausea, and abdominal swelling. The peritoneal space frequently accumulates fluid, making the ascites condition. Wasting symptoms gain their strength in course of time. All these symptoms (abdominal pains, abdominal weakness, weight loss, loss of appetite, nausea, and abdominal swelling) are the indications of abdominal mesothelioma. In case the patient suffers these symptoms, he is recommended to undertake further examinations in order to find out any other indicators of abdominal mesothelioma.
The organs of abdomen start suffering higher pressure due to the tumor enlarging. This can result to bowel obstruction and distention. The tumor advancing upward causes the breathing capacity reduction. In case the areas with plenty of nerve fibers are affected by abdominal mesothelioma and the bowel gets distended, the pain gets more severe.
The initial steps towards peritoneal mesothelioma detecting are generally x-rays and CT scans. A piece of tissue, obtained from the body gives the certain diagnosis. Peritoneoscopy is a medical procedure of examining the peritoneum. This procedure is held in the hospital with applying anesthesia. In case the doctor finds put any abnormality, he tries to conduct a biopsy - to get a sample of the tissue. Then a pathologist examines the tissue sample through analyzing specialized stains via microscope.
Asbestos fibers are supposed to have two ways to get to the peritoneum. The first way is to get to the mucus of the trachea and bronchi for being swallowed. Some fibers rest in the intestinal tract where they can continue their way to peritoneum passing through the intestinal wall. The second way is to be transported from the lungs by the lymphatic system directly to the peritoneum.
Medicine is still not completely aware of the fact how the carcinogen substance, for instance, asbestos, makes the cells cancerous (or malignant) on the cellular level, and why does it happen. It is as well impossible to say if the tumor is caused by only one fiber or a number of them is required, which premises and conditions cause these changes.
At present time peritoneal mesothelioma can be treated but cannot be cured. Treatment has different factors for prognosis, like the stage and the size of the tumor, the affected area extent and cell type, and the ability of the tumor to respond to treatment. Nevertheless, there are a lot of constantly improving abilities for peritoneal mesothelioma patients' relief and treatment. This is especially good news for the patients with the early-diagnosed and intensively treated peritoneal mesothelioma. The patients sometimes receive multimodal therapy that combines various therapies.
There are a number of treatments carried out experimentally and clinical trials, such as gene therapy and immunotherapy, and antiangiogenesis drugs.
Chrysotile Peritoneal Mesothelioma
This cancer linked with asbestos as well, aims its attack at abdominal cavity lining. Peritoneal mesothelioma is caused by the small fibers of chrysotile being swallowed or inhaled and settled down in the tissue. Peritoneal mesothelioma that is related to chrysotile can have quite long latency period sometimes lasting over 40 years between the exposure takes place and the disease diagnosed.
The pressure on the internal organs causes the pain in the abdomen to chrysotile peritoneal mesothelioma patients. Nausea, vomiting, bowel blockage, and swelling of the abdomen are the symptoms of chrysotile peritoneal mesothelioma. The chrysotile peritoneal mesothelioma is mostly too much advanced by the time it is diagnosed that doesn't allow the majority of its victims survive for more than a year after the symptoms apparition.
Due to the involvement of high asbestos concentration into this disease, chrysotile peritoneal mesothelioma is thought to happen to people who deal with chrysotile over their job. A considerable part of the chrysotile peritoneal mesothelioma patients used to be shipyard workers or worked in other areas where fireproofing and isolation was mounted with the usage of asbestos. One may have a contact with chrysotile peritoneal mesothelioma in case they are exposed to asbestos for a long time at work, at home or at school.
