Chemicals and Radiation Linked to Breast Cancer TEST

Chemicals and Radiation Linked to Breast Cancer

In our daily lives we are exposed to toxic chemicals and radiation from a wide range of sources, and large and growing body of scientific evidence tells us that some of these exposures can increase breast cancer risk. Exposures to breast carcinogens—chemicals that directly cause breast cancer—are an obvious concern. But we also must pay attention to exposures to chemicals that disrupt the body’s hormones—chemicals known as endocrine-disrupting compounds—as well as to physical agents such as ionizing radiation. Below is a catalogue of chemicals and physical agents that have been linked to breast cancer. Click on each link to discover what the science is telling us.
