Hereditary breast and ovarian cancer (HBOC) syndrome associated with mutations in the BRCA1 or 2 genes, comprises the largest single portion of known hereditary breast cancer syndromes. However, there are several other, less common hereditary cancer syndromes that also include a substantially increased risk for breast cancer. When evaluating a family for possible genetic testing, it is important to ensure that all appropriate syndromes are considered. Identifying the correct hereditary breast cancer syndrome can have significant impact on quality and length of life for the patient and their relatives.
