Genes, Environment, and Breast Cancer Story aired: Monday, October 25, 2004
Does genetics or environment have a greater impact on whether a woman will develop breast cancer? A new national study hopes to get to the bottom of that question by following the lives of 50,000 women whose sisters have breast cancer.
Researchers hope the 10-year study would provide them with clues to the genetic and environmental causes of the disease.
The role of genes in breast cancer is also the focus of a new Discovery Health Channel documentary, "Breast Cancer Legacy."
We also talk to a woman who decided to have her ovaries removed, even though she was cancer-free, in an attempt to beat the odds against breast cancer.
Guests:
Beth Murphy, filmmaker of "Breast Cancer Legacy," airing on Discovery Health Channel.
