Massage, Yoga, Acupuncture and Meditation for Veterans

Massage, Yoga, Acupuncture and Meditation
Veterans face a variety of stress-inducing situations while deployed and many of them walk away from service still suffering from stress and anxiety, sometimes severe enough to be considered Post-Traumatic Stress Disorder (PTSD). Soldiers also encounter situations that result in injuries that cause chronic life-long pain, and musculoskeletal problems are also quite common for those who've served in the military, both in combat situations and outside of combat. Still others have developed life-threatening illnesses like mesothelioma.
While prescription medications often work in reducing both stress/anxiety and pain, doctors or therapists often suggest complementary or alternative treatments for these problems. Many of these therapies have been used literally for centuries and have their roots in the ancient medicines of other cultures. Others are more modern. Nevertheless, most of them have proven to be quite advantageous in addressing common complaints voiced by veterans, promoting a feeling of calm and balance, especially after a particularly difficult deployment.

Mesothelioma Cancer

Mesothelioma is an aggressive cancer affecting the membrane lining of the lungs and abdomen.
Malignant mesothelioma is the most serious of all asbestos-related diseases. Although uncommon, mesothelioma cancer is no longer considered rare. The primary cause and risk factor for mesothelioma is exposure to asbestos.
Making a correct mesothelioma diagnosis is particularly difficult for doctors because the disease often presents with symptoms that mimic other common ailments. There is no known cure for mesothelioma, but treatments such as surgery and chemotherapy have helped to improve the typical mesothelioma prognosis.
Pleural mesothelioma (affecting the lung’s protective lining in the chest cavity) represents about three quarters of all mesothelioma incidence. Peritoneal mesothelioma which affects the abdominal cavity and pericardial mesothelioma, which affects the cardiac cavity, comprise the remainder. Testicular mesothelioma is extremely rare and is typically presents with metastases of the peritoneal variety. There are three recognized mesothelioma cell-types. Between 50 and 70% of all mesotheliomas are of the epithelial variety. While prognosis is generally poor, it is considered less aggressive than sarcomatoid mesothelioma and biphasic mesothelioma, which comprise the remainder of cell type diagnoses.

Types of Asbestos

Asbestos Types
Once mined in many places throughout the world but now mostly in Canada, Russia, Africa, and China, asbestos is a naturally-occurring mineral that was used for decades as an insulator for a host of products, many used in homes throughout the world.
Six different types of asbestos have been identified. These types are divided into two groups:

Tremolite Asbestos

A form of amphibole asbestos, tremolite is responsible for hundreds of cases of asbestos cancer diagnosed throughout the world, including in the United States. As with the other forms of asbestos that belong to the amphibole family, tremolite boasts sharp, needlelike fibers that easily enter the respiratory system when airborne, making it a particular toxic form of the mineral. This silicate mineral may range in color from creamy white to dark green, depending of the levels of magnesium or iron found in the mineral. 
Tremolite asbestos is often found in vermiculite - a natural mineral that expands when exposed to heat - though vermiculite mines are now routinely tested for the presence of tremolite. In the U.S., tremolite-contaminated vermiculite was responsible for the death of several hundred miners in Libby, Montana who worked at the local W.R. Grace Vermiculite Mine, which mined material for use in the company’s popular Zonolite insulation, used in millions of houses nationwide.

Vermiculite and Asbestos

Vermiculite is a naturally occurring, safe mineral that has been widely used for over 80 years in the insulation, construction, horticulture and agriculture industries. It has an appearance similar to mica and has a unique exfoliation property; that is, it expands to many times its original volume when it is heated. Its most familiar form is the white particles that appear in potting soil. This substance is plentiful worldwide and is mined on almost every continent. The most productive mines are located in the Palabora region of South Africa, the northwestern corner of China and in the eastern Appalachian range of Virginia and South Carolina.

The most productive mines are located in the Palabora region of South Africa, the northwestern corner of China and in the eastern Appalachian range of Virginia and South Carolina.
Although asbestos is not intrinsic to vermiculite, some sources of vermiculite do contain a substantial portion of asbestos. Asbestos exposure creates a risk of malignant mesothelioma or asbestosis. Specifically, vermiculite from the mines in Libby, Montana, contains tremolite asbestos. The Libby, Montana, mines were closed in 1990 due to health hazards related to asbestos exposure. Almost all of the vermiculite mined today comes from deposits that are geologically older (1.5 to 3 billion years) than those of Libby, Montana (225 million years).

Vermiculite Media Reports

Although a number of media outlets have cast doubt on the safety of vermiculite — including McCall's Magazine, National Public Radio, Newsweek and 20/20 — inspections show that current processing and use of this mineral is safe. For example, The Schundler Company, which is the largest processor of vermiculite, was inspected by the United States Environmental Protection Agency in 2000. The vermiculite was found to contain no asbestos during this inspection.
Any vermiculite that was mined and used in construction and insulation prior to the closing of the mines in Libby could conceivably contain asbestos. It is best if these materials are not disturbed, so as not to create any asbestos dust that could be inhaled. In cases where asbestos-containing vermiculite must be removed, standard hazardous material handling protocols should be used. Before removing and destroying any construction materials, it is best to have them tested for asbestos.
Researchers have evaluated the potential exposure to asbestos caused by the use of or exposure to vermiculite. They have not, however, provided any statistical evaluation of the risk of asbestosis, mesothelioma or lung cancer related to vermiculite exposure.
