Mesothelioma Cancer


Mesothelioma cancer is an uncommon, but no longer rare, form of cancer in which cells of the mesothelium (located in the chest) become abnormal and divide without control or order. These abnormal cells can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts ofthe body.

Thousands of new cases of mesothelioma cancer are diagnosed in the United States each year. Mesothelioma cancer (also known as asbestos cancer) occurs more often in men than in women and risk increases with age, but this disease can appear in either males or females of any age.

Tumors of the mesothelium can be benign (noncancerous) or malignant (cancerous). A malignant tumor of the mesothelium is called a malignant mesothelioma. Because most mesothelial tumors are cancerous, malignant mesothelioma is often simply called mesothelioma. Malignant mesothelioma is the most serious of all asbestos-related diseases.

Mesothelioma cancer is a disease that is almost 100% preventable because the only known cause is via exposure to the deadly mineral asbestos. The effects of asbestos on the human body have been known to be deadly for years. The normal latency period for Mesothelioma cancer (the time from exposure until the patient falls ill) is 20 to 30 years.

Symptoms


Symptoms of pleural mesothelioma include shortness of breath and pain in the chest due to an accumulation of fluid in the pleura. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling due to a buildup of fluid in the abdomen. Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face.

Asbestosis


Asbestosis is termed for the disease-causing particle of the same name. The pulmonary fibrosis (major lung damage) caused by asbestos fibers develops after years of exposure to these fibers. After the fibrosis becomes well established, the victim develops increasing breathlessness often with cough, sputum and weight-loss. Asbestosis is caused by inhaling asbestos fibers in the mining or milling of asbestos, generally in the textile, cement and insulating industries.

How Asbestosis Progresses


Asbestosis development starts when a person inhales an amphibole. This particle travels deep into the lungs to one of the 300 million gas-exchanging structures called an alveolus. Each alveolus has many cleaning cells called macrophages that eat up any particles that made it down to the alveoli. Unfortunately, the macrophages cannot eat the amphibole because it is too long, but they still try. In trying to eat this particle the macrophage essentially cuts itself open and the digestive molecules that were contained inside the macrophage have now spilled on the alveolus. These molecules injure the alveolus and cause it to form a scar. This scarring formation is called fibrosis. The same amphibole that could not be eaten attracts other macrophages from neighboring areas. They try to eat the particle and also fail, which further damages the lungs. People who are exposed to asbestos inhale hundreds and thousands of amphiboles, which causes large-scale injury. As a result, major lung damage (fibrosis) develops.

Signs and Symptoms


The signs and symptoms of asbestosis can show up many years after the asbestos exposure has ended. Manifestations rarely occur less than 10 years following first exposure and are more common after 20 years or more.

Symptoms of asbestosis may include:



The signs your doctor will look for in diagnosing asbestosis include:


Asbestosis is a chronic progressive disease, meaning that once these symptoms start, they generally do not get better. Unfortunately, there currently is no cure for asbestosis, but it does progress slowly which gives your doctor time to diagnose it and treat it, which increases your duration of survival and quality of life.
