What is a BRCA Gene? Connecticut Breast Imaging Explains

The Breast Cancer Gene: BRCA

Genes are pieces of our DNA that code for individual traits. We get one set of genes from each of our biological parents. While genes determine our physical traits, like the color of our hair or eyes, they also determine other characteristics. Genes are responsible for our blood type, immune system capabilities, and the general way our body works. 

What is a BRCA Gene?

BRCA is an abbreviation for breast cancer, and the BRCA gene is a gene that works to prevent breast and ovarian cancers from developing. Two genes impact a person’s breast cancer risk: BRCA1 and BRCA2. They work by blocking the uncontrolled growth of tumors. Everyone has BRCA1 and BRCA2 genes. Unfortunately, some people’s BRCA genes don’t function optimally, making them unable to suppress tumor growth. This type of abnormality is called a gene mutation.
