Hereditary Cancer and Genetic Testing

Genes with inherited mutations linked to breast cancer

Multi-gene panel tests look for inherited mutations in many genes at the same time. These tests may include new or less common genes. Some panels may include additional genes other than those listed below. A genetics expert can make sure that the most appropriate test is ordered based on your personal situation and family medical history. They will also make sure that your test results are interpreted correctly.
