Lizette Bigelow, a community health educator, discusses the role of genes in cancer. She explains how DNA and chromosomes function, the genetic changes that lead to cancer, and the factors causing these changes. The video emphasizes the importance of family history and genetic testing in understanding cancer risks. It concludes with resources for further information.
