Brca1 and brca2 – gene mutation testing: who should be tested and how to interpret the results?

Testing for BRCA1 and BRCA2 gene mutations has become increasingly popular and widespread in recent years.

This is an extremely important test that can help identify people susceptible to developing cancer, especially breast and ovarian cancer. In this article, we will discuss what exactly the BRCA1 and BRCA2 genes are, who should consider this test, how to interpret the results, and what can be done if the presence of BRCA1 and BRCA2 gene mutations is confirmed.

What does brca1 and brca2 mean?

BRCA1 and BRCA2 are genes responsible for producing proteins that help repair DNA damage in human bodies. Mutations in these genes can lead to impaired DNA repair, which increases the risk of developing breast, ovarian and other cancers. People who inherit defective copies of these genes from their parents may be at greater risk of developing these cancers.

Testing for brca1 and brca2 gene mutations – who should do it? why is it so important?

BRCA1 and BRCA2 gene mutation testing is recommended for people who meet certain risk criteria. Belong to them:

• People who have a family history of breast or ovarian cancer, especially before the age of 50.
• People who have had breast or ovarian cancer themselves, especially before the age of 50.
• People with a family history of male breast cancer.
• People with a family history of other cancers, such as pancreatic or prostate cancer.

This testing is important because it helps identify those at increased risk and take appropriate precautions, such as regular screening, preventive mastectomy or oophorectomy (removal of the ovaries).

Brca1 and brca2 testing – interpretation of results

BRCA1 and BRCA2 test results can be divided into several categories:

• Normal results: This means that no mutations were detected in the BRCA1 and BRCA2 genes, which is a good prognostic for cancer risk.
• Positive result: This means that mutations have been detected in one or both genes. People who test positive are at increased risk of developing cancer and should consult a doctor to discuss next steps.
• Inconclusive result: Sometimes results are difficult to interpret and require further testing or analysis of family history of cancer.

Confirmation of the presence of brca1 and brca2 gene mutations – what next?

If the presence of BRCA1 and BRCA2 gene mutations is confirmed, there are many treatment options. You could consider:

• Regular screening to detect possible cancers early.
• Prophylactic mastectomy or oophorectomy to reduce the risk of cancer.
• Health monitoring by specialists in the field of genetic oncology.
• The use of modern therapies and clinical trials in cancer treatment.

Your suggestions

If you have concerns about your genetic risk or would like to have your BRCA1 and BRCA2 gene mutation tested, please consult your doctor or genetics specialist. These are important steps that can help protect your health.
