Understanding the Links between Environmental Exposures and Cancer
American Recovery and Reinvestment Act of 2009 (ARRA)
"Recent studies have made it clear that many cancers, breast cancer in particular, occur primarily due to environmental exposure. However, research has only just begun into the types of exposure and diet that influence cancer and the time of life that an individual is at risk. Recovery Act funds are helping to find new insights into these complex problems by supporting unique projects sponsored by NIEHS that involve researchers, community partners, breast cancer advocates, and outreach experts."
— Les Reinlib, Ph.D., Breast Cancer and the Environment Centers (BCERC) Program Director
Cancer arises when cells are unable to repair DNA damage and experience abnormal cell growth and division. The process known as metastasis occurs when cancer cells travel to other parts of the body via the bloodstream and replace normal tissue. According to the American Cancer Society, this chronic disease is the second leading cause of death in the U.S. with half of all men and one-third of all women developing some form of cancer during their lifetimes.
The NIEHS is committed to understanding the connection between genetics and environmental exposures with regard to cancer.
Although cancer is responsible for 23% of all deaths in the U.S., millions of Americans have recovered from the disease. People may reduce their chances of getting cancer by employing prevention methods such as having regular screenings and living a healthy lifestyle.
How is the Recovery Act (ARRA) advancing cancer research?
NEIHS Recovery Act funds support projects addressing many research needs in regards to cancer pathways and exposure routes, and also specific cancers such as breast and skin cancer. The relationship between genes, the environment and disease plays a major role in many of the research studies.
