Breast cancer genetic test (BRCA 1 & 2 genetic testing)
Breast Cancer Genetic Testing
The lifetime risk of a woman developing breast cancer is 1 in 7. Most of these cancers are not inherited. There are a very small number of breast cancers that may be caused by the inheritance of a known faulty gene (BRCA1, BRCA2 or TP53).
A full family history risk assessment can be carried out, to determine whether one falls into a general population, moderate or high-risk category. Women at moderate or high risk may be offered enhanced screening, genetic counselling and genetic testing and even women at population risk may request this if funding this privately.
Individuals with hereditary breast cancer generally show one or more of the following clues:
• Triple-negative breast cancer
• Breast cancer diagnosed before the age of 45
• Bilateral breast cancer (cancer in both breasts)
• Several relatives with breast cancer
• Relatives with ovarian, prostate, pancreatic cancer or male breast cancer
• Jewish ancestry
Mr Agrawal can refer you for Genetic counselling, which takes place prior and after testing either by phone or face to face consultation. Testing for these genes can be carried out obtaining a blood sample.
When someone has an increased risk of breast cancer, it is usual for them to have screening mammography and often breast MRI scans. The frequency and timing of screening will depend on which genetic pathogenic variant is found and their age.
Those found to be carrying a faulty gene can be offered medication or surgery to reduce the risk of developing cancer.
