Second Hand Asbestos Exposure Causes Mesothelioma in Women

A woman who had never been directly exposed to asbestos, but who may have come into contact with it in her own home, has died from the asbestos cancer mesothelioma. Linda Sinnett, 58, was diagnosed with peritoneal mesothelioma, a rare form of cancer which affects the membrane that lines and protects the abdominal cavity.

Most cases of mesothelioma affect the lungs and chest cavity, but all forms of the cancer can usually be traced back to exposure to asbestos, a fibrous mineral which has frequently been incorporated into building materials and insulation products. Most cases of mesothelioma are diagnosed in individuals who have suffered this exposure at the workplace, but it’s also been known to occur in their loved ones as well, as a result of secondhand exposure.

When the microscopic asbestos fibers are disturbed, they become airborne and can be either inhaled or ingested. They can also cling to clothing, hair and other material, meaning that they can be transported from one location to another. Sinnett’s family assumes that she ingested the asbestos fibers after her father, Ronald, who was a carpenter for the Great Western Railway Works, brought asbestos home on his overalls. The laundry room where Sinnett’s mother would wash the overalls and other clothes was adjacent to the kitchen, and so it’s believed that the fibers contaminated the food and food preparation areas.

Sinnett was survived by a husband, John, 57, and their daughter Kerry Mills, 38.

Asbestos is no longer used as extensively as it once was, although it does remain in use in some limited capacities. It is also still in place in a number of older buildings and structures, so it continues to pose a hazard to anyone who works with or around the material without using the proper safety gear, such as protective clothing and respirators.

Mesothelioma is an unusual disease in that it can take decades to fully manifest and become symptomatic. Even then, the symptoms often resemble those of more common respiratory ailments, and are therefore often ignored or misdiagnosed. By the time an accurate diagnosis is made, the mesothelioma has progressed to a late stage and is usually inoperable.

Although radiation and chemotherapy can be given to reduce symptoms and alleviate pain, most patients who are diagnosed with mesothelioma have a life expectancy of less than two years.

Possible Genetic Predisposition To Mesothelioma

Medical researchers in North Carolina have announced a new study to investigate the possibility of a genetic predisposition to the development of mesothelioma. The Wake Forest School of Medicine in Winston Salem, NC and FirstHealth Carolinas, has undertaken research to better understand why only some individuals exposed to asbestos develop mesothelioma.

Dr. Jill Ohar of Wake Forest University, the study’s principal investigator, has spent more than 20 years studying mesothelioma. Her previous work includes research into understanding why some people and families appear more susceptible to developing the disease and whether such susceptibility could be inherited.

“Over years of research, we have determined that there is a strong tendency for mesothelioma to run in families and it tends to be associated with a family history of cancer, which suggests a genetic susceptibility,” Ohar said in a prepared statement about the current study released by FirstHealth Carolinas.

Compared to other groups who were exposed to asbestos, Ohar’s previous research has found that individuals who developed mesothelioma shared certain traits, such as an increased risk of cancer among relatives, according to an article on the research in the March 2007 issue of the medical journal Respiratory Medicine.

Similarly, the current study examines associated environmental factors and genetic markers of individuals diagnosed with mesothelioma to determine the particular genetic factors that make some families more susceptible than others to mesothelioma and other forms of cancer.

Chris Miller, director of clinical trials at FirstHealth Moore Regional Hospital, said the current study presented an exciting opportunity to increase understanding about the causes of mesothelioma.

“The FirstHealth Clinical Trials staff is excited about this opportunity to assist one of our state’s medical research institutions further the knowledge about this deadly disease and the factors that cause it,” Miller said.

FirstHealth of the Carolinas is a private, non-governmental, not-for-profit health care network serving 15 counties in the mid-Carolinas.
