Hereditary Breast Cancer

Breast cancer is the leading type of cancer that causes death in women. In Spain 20,000 new cases are diagnosed each year, with about 30% of cancer cases diagnosed. Higher prevalence figures are given in women aged 65 - 79, although 1 in 15 women aged 60 and 1 in 70 women under 30 years are affected by breast cancer. 

5-10% of all cases of breast and / or ovarian cancer can be attributed to mutations in high-penetrance genes transmitted by heredity. 

Women who carry mutations develop high probability of breast cancer during life, besides being highly aggressive cancer (onset at an early age, condition 2 breasts, ...). Specifically, it is known that mutations in the BRCA1 and BRCA2 genes are the main cause of hereditary breast cancer. Their study can help these families to make an accurate diagnosis and to make adequate prevention when necessary. 

Laboratory Echevarne offers:


Detects all possible specific mutations

found in these families.


Lets analyze gene rearrangements

not detected by conventional sequencing.
