Brief, Indirect Exposure Leads to Mesothelioma in Young Woman

ByAlex Strauss

26135126_asbestosA new report contains some disturbing news about just how little asbestos exposure it may take to cause malignant mesothelioma. Radiologists in New Delhi, India have published details of a case of mesothelioma in a young woman who experienced only very limited asbestos exposure as a child.

According to the article in the Journal of Clinical Imaging Science, the young woman was diagnosed with malignant pleural mesothelioma after complaining of chest pain and breathlessness. X-rays and CT scans revealed that, not only was she suffering from the asbestos cancer, but that it had also spread to her liver and lungs. A biopsy of one of the tumors confirmed the diagnosis.

In addition to being much younger than most mesothelioma patients, the woman’s case is unique in that her only known exposure to asbestos was from contact with the contaminated work clothes of her father 15 years earlier. Her father was a miner in the asbestos-rich Jharkhand area of eastern India. According to the report, the child only lived with her father for about three months.

“This report highlights that pleural and peritoneal mesothelioma can occur without direct asbestos exposure, as was seen in our young patient,” writes lead investigator, Dr. Bharati Singhal of the ESI Model Hospital in New Delhi. Dr. Singhal and his colleagues conclude that these kinds of short-term or second-hand exposures to mesothelioma-causing asbestos are probably underreported because neither patients nor investigators recognize their significance.

Mesothelioma is the most serious of a range of diseases, including lung cancer, linked with exposure to asbestos. Although most mesothelioma patients are diagnosed in their 60s or 70s – typically after many years of work-related exposure – the New Delhi case illustrates how dangerous asbestos can be, even in small quantities.

For this reason, more than 55 countries have banned asbestos mining, use, and importation. The US has not instituted such a ban, but has attempted to reduce mesothelioma risk among workers and the public through strict regulations on the handling of asbestos and asbestos-contaminated items.

    Mesothelioma survivor Paul Kraus, alive and well 19 years after writing “Surviving Mesothelioma and Other Cancers

    ByAlex Strauss

    Paul Kraus is considered the longest documented mesothelioma survivor in the world. He was diagnosed in 1997 with mesothelioma so widespread that he was given little hope of survival. Not willing to give up, he worked with a team of doctors to create his own tailored treatment protocol. This protocol included dramatic life style change, experimental therapies, dietary changes, mind-body medicine, and other modalities. Paul was fortunate. The protocol he and his doctors created helped him keep the mesothelioma in check. His book “Surviving Mesothelioma and Other Cancers: A Patient’s Guide” details his cancer voyage, the decisions he made, and his philosophies about health and healing. This book is now the best-selling mesothelioma book in the world and has inspired…

    Doctors Describe "Concrete Therapeutic Approach" for Mesothelioma

    ByAlex Strauss

    A team of medical researchers in Italy have achieved what they are calling “excellent” tumor control and survival results in malignant pleural mesothelioma patients using a combination of surgery, chemotherapy, and radiotherapy. Caused by exposure to asbestos, mesothelioma typically spreads quickly across the lung-encasing membrane called the pleura. There is no known cure but treatments are improving. In the current prospective study, 20 malignant pleural mesothelioma patients underwent radical pleurectomy/decortication followed by high doses of radiation. After surgeons removed as much of the visible mesothelioma tumor and surrounding tissue as possible, patients received 50Gy of radiation to the effected side of their chest, delivered in 25 fractions. Regions of particular concern for mesothelioma regrowth got an extra radiation “boost” to…

    Mesothelioma Still Rising Despite Ban in Ireland

    ByAlex Strauss

    A study in Ireland confirms that it can take many years for a ban on asbestos to have a measurable impact on a country’s rates of malignant mesothelioma. Mesothelioma is the most serious of a list of diseases – including lung cancer, pleural plaques, asbestosis, and others – linked with exposure to asbestos dust. Affecting the linings around the lungs and other organs, mesothelioma is often resistant to most cancer treatments and may be fatal within a year of diagnosis. According to the International Ban Asbestos Secretariat, Ireland is one of 55 countries that have enacted some type of asbestos ban. However, although Ireland banned asbestos in 2000, a new study published in Cancer Epidemiology shows that incidence of the…

    Does Radiotherapy Reduce Mesothelioma Pain?

    ByAlex Strauss

    A new study says there is not enough evidence to support the use of radiotherapy for the treatment of pain associated with malignant pleural mesothelioma. Researchers at the University of Edinburgh in Scotland reviewed a range of past studies on mesothelioma pain and radiotherapy by searching databases that date back as far as 1974. To be eligible to be included in their review, the study had to focus on malignant pleural mesothelioma and radiotherapy given “with the intent of improving pain”. The study also had to report doses and fractionation of the radiotherapy and how the pain responded. In all, the researchers found eight studies on mesothelioma pain and radiotherapy that met the criteria. Two of the studies were prospective…

    Website Aims to Protect Homeowners from Mesothelioma

    ByAlex Strauss

    Australia’s Cancer Council is trying to educate home renovators about their risk for mesothelioma with a new e-learning course. Australia has one of the highest per capita rates of mesothelioma in the world, largely because of several asbestos mining operations that were once located there. Although asbestos has been banned from building products in Australia since 1989, asbestos-linked diseases like mesothelioma, lung cancer, and asbestosis continue to pose a serious health concern. While mesothelioma has traditionally occurred among people exposed to asbestos on the job, Australia is now bracing for another “wave” of mesothelioma victims among homeowners who encounter asbestos while doing their own renovation projects. Cancer Council Australia has launched “kNOw asbestos in your home” in an effort to…

    Ape Virus Shrinks Mesothelioma Tumors in Lab

    ByAlex Strauss

    A virus that causes leukemia in gibbon apes may have the power to help fight malignant mesothelioma in people. Gibbon ape leukemia virus (GALV) has been tested for years as a viral vector, a carrier of therapeutic genetic information, in the treatment of various human illnesses, including cancer. A new study in Japan compared GALV with a leukemia virus derived from mice to see which carrier communicated most efficiently with mesothelioma cells. While both types of viruses replicated in most of the mesothelioma cell lines tested, the mouse-derived virus was not effective in a mesothelioma cell line called ACC-MESO-1. In this cell line, only the GALV spread efficiently both in culture and in mice that had been given human mesothelioma…
