Visiting Speaker: Mark Goldberg "Occupational Exposure and Postmenopausal Breast Cancer"
Wednesday, September 29, 2010 12:00 pm to 01:00 pm
Venue: 480 University Ave. Suite 300, Toronto, ON M5G 1V2


Presenter: Mark Goldberg

Results will be presented from a case-control study conducted between 1996 and 1997 in Montreal, Quebec that examined the relationship between occupational exposures to organic solvents and other agents and the increased risk of developing postmenopausal breast cancer. Cases comprised 556 women, aged 50-75 years, with incident malignant breast cancer, and their controls were 613 women with other cancers, frequency matched for age, date of diagnosis and hospital. Using the 'Siemiatycki method,' the study used a chemical coding team to translate detailed job descriptions to occupational exposure with approximately 300 agents.

Results indicate that there were increased risks to extremely low frequency electromagnetic radiation, synthetic fibres, organic solvents with reactive metabolites and to polycyclic aromatic hydrocarbons derived from the combustion of petroleum.

In addition to this event, Mark Goldberg will be presenting at the following institutions on the same date:

  • 8:00 am - St. Michael's Hospital on the topic of "Intraurban air pollution and cancer: Associations between prostate cancer and breast cancer in Montreal." For more information, please visit:
  • 2:00 pm - University of Toronto, Wallberg building, room. 420, on the topic of "Acute Health Effects from Changes in Air Pollution and Weather in Heart Failure."

Mark Goldberg is a Professor at the Department of Medicine, McGill University; Medical Scientist at the Royal Victoria Hospital, McGill University Health Centre, and Co-editor in Chief of Environmental Research.
