Mesothelioma and Lung Cancer Information Center
Advanced Cancer Help is part of the Renaissance Healthcare Systems network and is dedicated giving our patients and their families the best quality healthcare available. We invite you to join us in sharing your information in the battle against mesothelioma. With the latest news and information regarding mesothelioma treatment, clinical trials, research and cancer survivors.
Renaissance Healthcare offers both medical assistance for you or your loved one and legal assistance through specialized mesothelioma attorneys. Our primary concern is treatment of the overall patient and seeking to provide the highest "whole life" care. Patients who have been diagnosed with mesothelioma or asbestosis can receive financial settlements to help them offset patient care costs.

Types of Mesothelioma:
Pleural mesothelioma is a cancer of the cells that make up the pleura or
lining around the outside of the lungs and inside of the ribs. Its only
known cause in the U.S. is previous exposure to asbestos fibers, including chrysotile, amosite or crocidolite. This exposure is likely to have
happened twenty or more years before the disease becomes evident, since it
takes many years for the disease to "incubate." It is the most common type
of mesothelioma, accounting for about 75% of all cases.
Peritoneal mesothelioma is a tumor of this membrane. Its only known cause in the U.S. is previous exposure to asbestos, but it can be many years after exposure before the disease appears. Peritoneal mesothelioma account for about one-fifth of all mesothelioma.
Pericardial Mesothelioma is a tumor that can occur at any age with a mean age of 46 years at presentation. Patients present with chest pain, dyspnea, cough, and palpitations. Although there appears to be a strong link to asbestos exposure, a definite association has not been established due to the rarity of this lesion. Surgery combined with radiation therapy may provide some palliation, but the prognosis is extremely poor. On CT there is irregular, diffuse pericardial thickening and a pericardial effusion. Pericardium is a thin lining of tissue surrounding the heart.
Symptoms of Mesothelioma:
When the symptoms of peritoneal mesothelioma appear, they typically include abdominal pains, weakness, weight loss, loss of appetite, nausea, and abdominal swelling. Fluid often accumulates in the peritoneal space, a condition known as ascites. Over time the wasting symptoms can become more and more severe.
The growing tumor can exert increasing pressure on the organs in the abdomen, leading to bowel obstruction and distention. If the tumor presses upward, it can impair breathing capacity. If the tumor pushes against areas with many nerve fibers, and the bowel distends, the amount of pain can increase.
The treatment options for people with mesothelioma have improved significantly, especially for those whose cancer is diagnosed early and treated vigorously. Many people are treated with a combination of therapies, sometimes known as multimodal therapy.
Specific types of treatment include:
There are also experimental treatments like gene therapy and immunotherapy, angiogenesis inhibitors, and clinical trials for various new treatments and combinations of treatments.
Treatments that reduce pain and improve lung function, are becoming more successful (although they cannot cure mesothelioma.) Pain control medications have become easier to administer. Debulking is a surgical process of removing a substantial part of the tumor and reducing the pleural thickening; this can provide significant relief. X-ray therapy has also been successfully used to control the tumor and the pain associated with it for a while.
Surgery is a common treatment of malignant mesothelioma. The doctor may remove part of the lining of the chest or abdomen and some of the tissue around it. Depending on how far the cancer has spread, a lung also may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.
Radiation therapy uses high-energy x-rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from putting materials that produce radiation (radioisotopes) through thin plastic tubes in the area where the cancer cells are found (internal radiation therapy).
There is as yet no known cure for malignant mesothelioma. The prognosis depends on various factors, including the size and stage of the tumor, the extent of the tumor, the cell type, and whether or not the tumor responds to treatment. KMESA has represented many clients who lived for five to ten years after diagnosis, most of them in good health for a majority of those years. Some mesothelioma victims succumb within a few months; the average survival time is about a year.
X-rays and CT scans are, typically, the first step towards detecting peritoneal mesothelioma. The actual diagnosis is typically achieved by obtaining a piece of tissue. The medical procedure of looking at the peritoneum is known as a peritoneoscopy. It is a hospital procedure and requires anesthesia. If an abnormality is seen, the doctor will attempt to obtain a tissue sample - this is known as a biopsy. The tissue sample will be examined by a pathologist who makes a diagnosis using microscopic analysis of specialized stains.
There are at least two explanations for how asbestos fibers can get into the peritoneum. The first is that fibers caught by the mucus of the trachea and bronchi end up being swallowed. Some of them lodge in the intestinal tract and from there they can move through the intestinal wall into the peritoneum. The second explanation is that fibers that lodge in the lungs can move into the lymphatic system and be transported to the peritone
