20 Years After BRCA: What We’ve Learned About Genetics and Breast Cancer

Twenty years ago, scientists announced the discovery of BRCA1, which arguably has become the best-known cancer susceptibility gene in the world. When inherited in a mutated form, the gene sharply increases a woman’s chances of developing breast or ovarian cancer, often at an early age. The discovery has changed the way women with a family history of breast and ovarian cancer approach these diseases, helping them better understand their risk and the options for reducing it. It also presents them with complex choices about sharing genetic test results with family members who may also carry the mutated gene. The hunt …

The Truth About BRCA Testing and Genetic Risk

Huma Rana, MD - SMALL

Cancer genetics has come a long way in the last two decades, leading to increased prevention and improved treatment options. Today, research is shining the light on why certain people have an increased risk for cancer. “It took us 20 years to get where we are today with the knowledge of BRCA1/2, but we are starting to find changes in other genes that are explaining a history of cancer in families,” says Huma Q. Rana, MD, clinical director for Dana-Farber’s Center for Cancer Genetics and Prevention. “These new genes we’re identifying are likely to make a difference in prevention and …
