Solvent ‘raises risk of cancer’

A solvent found in varnishes, paints, dyes and fuel additives and which is used in the semiconductor industry may raise the risk of cancer among women taking hormone treatments, say researchers. They found the chemical, ethylene glycol methyl ether (EGME), boosted the activity of hormones used in HRT and the contraceptive pill. This may increase the risk of breast or ovarian cancer for some women.

European consultation on cutting work cancer and reproductive risks

The European Commission is consulting workers and employers on reducing exposure to work substances that cause cancer and reduce fertility. It says it wants views on how to tackle gaps in existing legislation aimed at minimising exposure to substances that cause cancer and have other harmful effects. The consultation document asks four main questions: Should the current cancer directive be extended to cover reproductive hazards; should the number of substances covered by the Directive be increased; are the exposure limits in the existing Directive appropriate; and should measures be taken to make the procedures within the Directive simpler and more adaptable to scientific progress?

US chipmakers’ cancer study too little, too late

A microelectronics trade group has said it is to sponsor a study on cancer risks in semiconductor manufacturing facilities. George Scalise, president of the Semiconductor Industry Association (SIA), said: ‘This industry has always looked for ways to improve the manufacturing processes that lower environmental impacts and improve the health and safety conditions for our employees.’ Critics have charged for years, however, that the chipmaking industry has stalled efforts to create good data on cancer and other risks in the plants. ‘It’s kind of a day late and a dollar short,’ said Ted Smith of the Silicon Valley Toxics Coalition. Smith said the study could be a good sign but that its credibility would depend on who actually performed the research and on whether there would be a third-party oversight panel to certify the findings.

The cancer epidemic as a social event

This Canadian criticism of the role of capitalism in creating environments conducive to cancer and then burying the costs along with the victims, concludes a different  approach is needed if cancer is to be prevented. “We can win the war against cancer. The best available research is necessary, but not sufficient, for our victory. Cancer research is designed and undertaken, and the results published and acted upon, in a deeply political context. The social, political and economic changes necessary to win the war against cancer will require more than research alone. It will also require collective action, the uniting of movements that have operated for the most part independently. The combined wisdom and skills of activists in the environmental, occupational health, women’s health and nutrition movements will be needed to successfully challenge the status quo and to insist that science, the state and corporations operate in the public interest. That is what is needed to stem the cancer tide that is sweeping across Canada and beyond.”

UK faces asbestos cancer epidemic

The United Kingdom is facing an epidemic of mesothelioma cancers among workers exposed to asbestos, top doctors have warned. Writing in the 31 January edition of the British Medical Journal they say there are now over 1,800 mesothelioma deaths per year in Britain – more than one in 200 of all deaths in men and almost one in 1,000 in women – and the number is still rising, with the peak of the epidemic still to come.

Work cancer risks to women are ignored

Estimates that 1 per cent of cancer among women is attributable to occupation are based on research conducted mainly in the 1970s among men in developed countries. These studies do not reflect the dramatic changes in the participation of women in the workplace or the patterns of employment of women in developing countries. The proportion of women in the paid workforce, the amounts and types of unpaid labour, the distribution of women by economy sector, the scale of the workplaces, the allowable exposure levels in the workplace, and implementation of controls have changed over time and vary internationally. Occupational cancer researchers need to expand their focus on women, increase activities in developing countries, include newly created industries, use sophisticated exposure assessment methods, and, where appropriate, incorporate molecular epidemiologic techniques to discover new occupational carcinogens and to identify where better control measures are needed. The Doll/Peto study almost entirely discounted occupational cancer risks to women.

The chemical industry’s secret toxics defence plan

A chemical industry covert plan to undermine safety campaigns, including the creation of phony front groups and spying on activists, has been unearthed in a memo obtained by Environmental Working Group (EWG). The memo recommends that the American Chemistry Council (ACC), the lobbying association for US chemical companies, hire a crisis communications firm that promotes itself as the attack dog of the public relations industry to fight back against California’s adoption of laws and regulations that embrace the ‘precautionary principle’ (PP).

Asbestos industry dirty tricks campaign revealed!

An asbestos industry dirty tricks campaign to give the deadly fibre a healthy gloss has been uncovered. A paper in the November 2003 edition of the American Journal of Industrial Medicine (AJIM) concludes: ‘The Canadian asbestos mining industry has a long history of manipulating scientific data to generate results that support claims that their product is ‘innocuous’.’ The US research team adds that the industry does this by retaining its own, industry sympathetic researchers.

Warning on cancer drug dangers

The HSE is warning workers of the need to observe stringent safety procedures when handling highly dangerous cancer drugs. A free information sheet aimed at the health and veterinary workers who handle the ‘cytotoxic drugs’ – also known as antineoplastic, anticancer or chemotherapy drugs – says they should be aware of serious long term risks if they are not handled in a safe manner.

Chip makers ‘must have known’ of cancer risks

Attorneys in a major Silicon Valley cancer cluster lawsuit against IBM have uncovered a ‘corporate mortality file” in which IBM tracked the deaths of more than 30,000 workers – and the lawyers claim the company knew its electronics workers were dying of cancer more often than normal. The IBM death records were reviewed by a medical expert hired by former IBM workers ahead of a September 2004 court case. The analysis by Boston University epidemiologist Richard Clapp concludes: ‘By 1975, IBM must have known their manufacturing employees had significantly increased death rates due to cancer and must have known that through the next two decades.’ He says data suggest that IBM workers were much more likely to die from cancers of the breast, blood and lymph than the general population.
