5-10% of cancer cases are hereditary. These are cases where the development of cancer is the result of mutations in specific genes.
Hereditary breast and ovarian cancers are often associated with mutations in the BRCA1 and BRCA2 genes.
On average, 500 in 1 people have a BRCA1 gene mutation.
On average, one in 225 people has a BRCA2 gene mutation.
PRESENTIA The BRCA1/BRCA2 hereditary cancer panel examines mutations in these genes, which can cause many cancers in the future.
