Raised in small-town Illinois, cancer seems to run in Sandra Steingrabers family. Sandra was diagnosed with bladder cancer when she was just twenty years old. Her mother was diagnosed with breast cancer when Sandra was in high school. Many of her aunts and uncles have struggled with the disease. One aunt even died from the same form of bladder cancer that Sandra had. But while cancer runs in her family, she cannot say that it runs in her genes. Sandra is adopted. This unusual twist led Sandra to ask what else families have in common besides their DNA. The answer is all around us: our environment. Based on the acclaimed book by ecologist and cancer survivor Sandra Steingraber, Ph.D., Living Downstream is an eloquent and cinematic feature-length documentary. This poetic and character-driven film follows Sandra during one pivotal year as she travels across North America, working to break the silence about cancer and its environmental links.
