Mesothelioma may be caused by exposure to ultramafic rock

Everyday exposure to naturally occurring asbestos increases the risk of developing malignant mesothelioma, according to a study by UC Davis researchers. The study - the largest to examine the question - will be published this fall in the American Journal of Respiratory and Critical Care Medicine. Exposure to asbestos in the workplace, particularly in shipyards, has long been recognized as a risk factor for mesothelioma, a rare form of cancer affecting the lining of the lung. But in the new study, researchers found a consistent and dose-dependent association between mesothelioma and residential proximity to ultramafic rock, the predominant source of naturally occurring asbestos. "Our findings indicate that the risks from exposure to naturally occurring asbestos, while low,...

Nanotech could cause mesothelioma

Carbon nanotubes3D model of three types of single-walled carbon nanotubes. (Wikipedia: Michael Stroeck, file photo)In the 1990s scientists found a way to roll carbon atoms into a cylinder, called a nanotube. Now US researchers have found that the lungs of mice respond to some fibres from nanotubes as they would to asbestos, forming lesions and becoming inflamed.Dr Andrew Maynard from the Woodrow Wilson International Centre for Scholars told AM nanotubes are excellent at conducting heat and electricity. They're already being used in sports equipment because of their strength."Almost like a miracle material. If only we could make it in large quantities...

Newest technique which can help diagnose mesothelioma

A new technique may help clinicians hone in on a diagnosis in patients presenting with a pleural effusion of unknown cause. The study will appear in the Sept. 1 issue of the American Journal of Respiratory and Critical Care Medicine. "Pleural effusion, or the accumulation of fluid in the pleural cavity, can be maddeningly difficult to diagnose as a wide variety of malignant and benign causes exist," said Helen Davies, specialist registrar and research fellow at the Oxford Center for Respiratory Medicine and Oxford University, lead author of the study. "One of the causes, malignant pleural mesothelioma, is a relatively rare cancer, but its incidence is rapidly increasing on a global scale." Currently, the first-line test for mesothelioma in patients with a pleural effusion is pleural...

Causes of Cancer

Cancer is a class of disease characterized by out-of-control cell growth. With more than 200 different types of cancer, one can develop it in virtually any organ of the body. Research states that there are more than 60 different organs in the body where cancer can develop.Typically, one form of cancer will develop in certain areas of the body. However, since cancer can develop from almost any type of cell, it is also possible that more than one type of cancer can develop in any one part of the body. For example, one can develop pleural mesothelioma or pericardial mesothelioma, two different types of cancer, even though they both form in, and around, cardiac muscles.Ultimately, cancer is the result of cells that grow uncontrollably and do not die. Whereas normal cells in the body go through...

Cancer Myths and Misconceptions

Myths can cause hypochondriacs and the like to unnecessarily worry about their health. Frightening claims on the internet circulate daily about new products causing cancer. Besides most of the claims being bogus, many of these accusations cause people to worry about their health, and the health of their families for no reason. One should get all the facts before jumping to conclusions. Below is a list of common myths about cancer and whether or not there’s any truth to them. Myth: Deodorant can cause breast cancer.Fact: Although a few reports have suggested that some deodorant products contain harmful substances such as aluminum compounds and parabens that can be absorbed through the skin, there’s no conclusive evidence linking the use of underarm antiperspirants with breast cancer. According...

Breast Cancer

Breast cancer is the second most common cancer among women in the United States. While men have been diagnosed with this cancer, women are 100 times more likely to develop breast cancer over men.Breast cancer is a type of cancer that forms in tissues of the breast. It usually originates in the ducts (tubes that carry milk to the nipple) but it can also form in the lobules, the glands that produce milk. Most breast lumps are benign (not cancerous), however some may need to be sampled under a microscope to make certain that they are not cancer.Certain women are at higher risks of getting breast cancer than others. Age, family history and genetic makeup are not things that can be altered; however there are external risk factors that can be controlled. These risks include:Drinking more than two...

Cancer Overview

There are more than 100 diseases that fall under the broad umbrella of “cancer.” The uniting feature of these diseases is abnormal cell division – cancerous cells are those that grow out of control. Though cell division is an important bodily process that allows for growth and repairing injuries, when the DNA safeguards that control division rates fail, cancer develops. These cancerous cells often invade other, healthy tissues, something normal cells cannot do.Damage to a cell’s DNA may cause it to replicate instead of die when it is no longer needed, creating more cells with damaged DNA. A variety of factors can cause this damage, from genetic abnormalities to environmental causes like smoking or asbestos exposure. However, the cause is not always known. If cancerous cells spread to...
