NOVA: Cracking Your Genetic Code | Should We Screen for Cancer Genes?

This video excerpt from NOVA examines the dilemma some people face when they are deciding whether to undergo genetic testing. Journalist Catherine Elton describes her decision to refuse a test for BRCA1, a mutation that signals an increased risk of breast and ovarian cancers, despite the history of disease in her family. The video also explains that genetic testing results can help some individuals improve their wellness, prevent the onset of diseases they are at risk for, or lessen the harmfulness of diseases they do contract. This video is available in both English and Spanish audio, along with corresponding closed captions.
