Hereditary breast and ovarian cancer (HBOC) syndrome is a relatively new science. This means the landscape is constantly changing. Below is a list of the most recent 'risky genes' being tested for, which represent the bulk of those discovered to date. Only a portion of this type of hereditary cancer has been explained, so this list is expected to grow over time. 


In the not too distant past genetic tests only looked for BRCA genes. Those with a family history of cancer who received a negative result for BRCA gene mutations may want to consider being re-tested with a more comprehensive gene panel.  This also goes for those returning a negative result with today's gene panels who may want to revisit genetic testing in a few years when more genes have been added.
