mesothelioma asbestos

Tumors of the mesothelium can be either benign (non-cancerous) or malignant (cancerous). Since malignant mesothelioma is much more common than benign mesothelioma it is often simply called mesothelioma. Characteristics of a malignant tumor are that it has the ability to spread to other parts of the body, making it much more dangerous.

Malignant mesothelioma is divided into three types: epithelioid, sarcomatoid, and mixed/biphasic. 50% to 70% of mesothelioma cases are epithelioid, which also has the best prognosis (outlook for survival). 7% to 20% are of the sarcomatoid type, and 20% to 35% are the mixed/biphasic type. Epithelioid affects the membranous tissue covering internal organs and other internal surfaces of the body. Sarcomatoid arises from supportive tissue, such as bone, muscles, cartilage, or fat. Biphasic mesothelioma has features of both epithelioid and sarcomatoid. The treatment options are the same for each type.

Mesothelioma Cancer

mesothelioma Previously, diagnosing mesothelioma in its early stages had been a difficult, almost impossible task, because the early symptoms of this disease resemble those of similar diseases and sometimes even basic illnesses. The severity of mesothelioma is defined by four stages, with prognosis becoming bleaker as each stage progresses, so the discovery of symptoms in the first two stages is essential for ensuring a greater mesothelioma life expectancy. Additionally, the difficulty in diagnosing mesothelioma cancer is caused by a long latency period, meaning that it can take decades between the initial exposure to asbestos and development of symptoms. However, if you or a loved one has been exposed to asbestos and experiences initial symptoms such as chest pain, violent coughing, and fatigue, it is essential that you consult with a physician immediately.

malignant pleural mesothelioma

Pleural mesothelioma is the most prevalent of all types of mesothelioma. It affects the soft tissue surrounding the lungs known as the pleura or pleural membrane. Mesothelioma tumors can develop in multiple locations throughout the body, but they originate from the pleura in approximately 75 percent of all cases. In each case, cancer forms in the mesothelioma, a tissue membrane that protects various organs and body cavities.

Pleural mesothelioma is typically caused by occupational exposure to airborne asbestos fibers. Because this exposure is frequently in male-dominated industries, around 80 percent of all pleural mesothelioma patients are men. Once inhaled into the lungs, needle-like asbestos fibers migrate to the pleural membrane, where the body cannot easily get rid of them. Fibers irritate the pleura, which can result in chronic inflammation and scarring. Infrequently, this causes pleural mesothelioma.

Over an extended period of time – usually three or more decades – asbestos triggers genetic changes in the pleural cells. If the cells become cancerous, they begin to divide uncontrollably, forming tumors that reduce lung capacity and generate excess fluid buildup between the pleural layers.

The overall outlook for pleural mesothelioma patients is poor. This is because symptoms do not usually arise until more advanced stages of cancer where curative surgery is no longer an option. However, an early diagnosis facilitates the most effective treatment options, potentially improving a patient's outlook and life expectancy.

Mesothelioma Treatment

Mesothelioma Treatment Once an individual has been diagnosed by a qualified mesothelioma doctor, the next step is to discuss mesothelioma treatment options and to develop a treatment plan. Recent scientific research has produced significant breakthroughs with regard to treatment protocols for mesothelioma patients and more options are now available for managing mesothelioma and supporting improved quality of life. Newly diagnosed mesothelioma patients often have many questions for their doctors about the treatment options that would be most effective for them. Conventional treatment options for mesothelioma include surgery, radiation and chemotherapy. Recently, chemotherapy drugs including Alimta® and Cisplatin have showed promising results in some patients.

Mesothelioma clinical trials as well as experimental treatments are other options that certain mesothelioma patients may be eligible to participate in. Our site features a comprehensive mesothelioma cancer treatment section that includes important information for patients and families. We've included resources on top mesothelioma experts such as Dr. Sugarbaker, as well as a comprehensive list of cancer centers where mesothelioma treatment takes place. Beyond the conventional treatments for mesothelioma, certain alternative therapies may provide assistance to mesothelioma patients. We continually update this section of our site as new mesothelioma treatment information becomes available. Check back often to read about the most recent advances.
