What is cascade screening?

Some genetic conditions can be passed from parent to child, generation to generation, affecting multiple family members. Cascade screening is a way to identify and test the relatives of people who have particular genetic conditions that may “run in the family,” such as Lynch Syndrome and Hereditary Breast and Ovarian Cancer Syndrome.

When a person is diagnosed with one of these conditions, their family members are at heightened risk for that condition too. Unlike some other genetic conditions, Lynch Syndrome and Hereditary Breast and Ovarian Cancer Syndrome are “autosomal dominant” conditions. This means there is a 50% chance of a parent passing on the condition to their child.

That's why it's so important to talk with relatives about getting screened. Cascade screening gives health care professionals a chance to detect these conditions early and provide appropriate medical recommendations. Those at risk often include first- and second-degree biological relatives such as parents, siblings, children, uncles, aunts, nieces, nephews, grandparents, grandchildren, and half-siblings. If you or a family member is diagnosed with a genetic condition, talk with your health care provider about the condition and cascade screening.
