Our genes tell a lot about us, and reveal our history in a multitude of ways. Genetic DNA is what gave you your grandmother’s type of curly hair or your great-grandfather’s tendency to develop freckles in the summer.
But genes can also pass along unwelcomed predispositions, such as disease. When there is a strong family history of a disease like breast cancer, it’s possible for that abnormal gene to be inherited by generation after generation.
While you may not be a DNA expert, it’s important to educate yourself about three of the well-known genes that can mutate and raise the risk of cancer.

BRCA1 + BRCA2:
These are two human genes that produce proteins, which suppress tumors. When either of these genes is inherited in a mutated or altered form, women have a higher risk of breast or ovarian cancer.
This acts as a partner to the BRCA2 gene. Similar to the BRCA genes, abnormal PALB2 raises the risk of breast and ovarian cancer. Men with these mutations also have an increased risk of breast cancer, especially if the BRCA2 gene is affected as well.
You or someone you know may have had a type of breast cancer that was influenced by family history. When this happens, the odds are high that it was mutation of these three genes.
In an effort to prevent breast cancer, some people choose to test their genetic makeup to find out if they carry any mutations. Here are 9 Reasons to Consider Breast Cancer Genetic Testing.
