Cascade Testing is one of the most important steps in breaking the cycle of hereditary cancer in families. This testing-sharing-testing-sharing of genetic information plays a vital role in protecting the health and lives of loved ones in families with a history of cancer. 

Cascade testing requires two very important steps: 

1. Having testing done. 
2. Sharing information. 
That includes sharing test results and the specific mutation in the gene, like 5385delAG in BRCA1. 
The information should be shared with all these living genetic relatives: parents, siblings, aunts, uncles, nieces, nephews, and cousins.
