The BRCA Gene
BRCA Explained.
BRCA is a gene, something everyone is born with.
The BRCA genes, known as BRCA1 and BRCA2, are important parts of our DNA that help protect us from all kinds of cancer. They produce proteins making sure our cells stay healthy. However, when there’s a mutation or change in these genes, their ability to do this reduces, which increases the risk of developing cancers.
Having one of these faulty genes means that you are more likely to get breast cancer than someone who doesn’t. But it is not a certainty. Researchers estimate that only around 5 to 10 out of 100 breast cancers (5 to 10%) are caused by an inherited faulty gene.*

BRCA mutation runs in the family, what does that mean for me?
Remember that most cancers are not related to inherited genes (source: Breast Cancer Research UK), and not everyone with a BRCA mutation will develop breast cancer; many factors influence cancer risk, including family history, lifestyle, and age.
If a BRCA mutation does run in the family, you can get yourself tested, and then discuss your options and considerations with a healthcare specialist should you have the same mutation. Book an appointment with your GP who can refer you for testing.
If there is a history of breast cancer in your family and you are worried, please talk to your GP or another secondary care provider. They can refer you to the Breast Clinic where you will be assessed to see if you meet the criteria for genetic testing.
You’re not alone in this.
Understanding your genetics can be a powerful tool in managing your health.
“I’ve known for years that my mum is a BRCA carrier, and that the gene runs in the family.”
“It wasn’t until after the birth of my daughter and going to my 6 weeks post-partum check with the Doctor - the Doctor that would save my life - that I thought seriously about getting tested.”
