Description

The BRCA1 and BRCA2 tests identify whether a person carries specific gene mutations that can significantly increase the risk of developing certain cancers, particularly breast and ovarian cancer. This information allows individuals to take proactive steps in managing their health based on their genetic predisposition.

Key Points About BRCA1 and BRCA2 Testing

Function of BRCA Genes:

  • BRCA1 and BRCA2 are essential for DNA repair.
  • Mutations in these genes can disrupt normal DNA repair, increasing the risk of cancer development.

Who Should Consider Testing:

  • Individuals with a strong family history of breast or ovarian cancer, especially if diagnosed at a young age.
  • Those seeking to understand their inherited cancer risk for proactive health planning.

What the Test Looks For:

  • A blood sample is analyzed to detect harmful mutations in the BRCA1 and BRCA2 genes.

Positive Test Results:

  • Indicate a higher risk of developing breast or ovarian cancer.
  • May lead to enhanced cancer screening, lifestyle modifications, or preventive measures such as risk-reducing surgery.

Fasting: Not required.
