Genetic testing for breast cancer is a type of medical test that looks for changes in genes that are associated with the development of breast cancer. This testing can be used to determine if someone has an increased risk of developing breast cancer, and can also be used to help guide treatment decisions. There are several different types of tests that fall under the umbrella of “genetic testing of breast cancer,” and the specifics of each test can vary.
Genetic testing for breast cancer Causes
- To identify specific inherited genes that may predispose an individual to develop breast cancer.
- To assess an individual’s risk of developing breast cancer based on their genetic profile.
- To guide decisions about preventive measures, such as increased surveillance or prophylactic surgery.
- To inform treatment decisions for individuals who have been diagnosed with breast cancer.
- To evaluate the effectiveness of certain treatments based on an individual’s genetic profile.

Genetic testing for breast cancer is a Risk factor
- If a woman has a first-degree relative (mother, sister, daughter) with breast cancer, her risk increases to about 20%.
- A woman’s risk is also increased if she has certain genetic mutations, such as BRCA mutations.
- If a woman has a family history of breast cancer, she may choose to have genetic testing to see if she has a BRCA mutation.
- If she does have a BRCA mutation, her risk of developing breast cancer is about 50%.
- Genetic testing can also help doctors recommend the best treatment options for a woman with breast cancer.
- A woman should talk to her doctor about whether genetic testing is right for her.
Genetic testing for breast cancer Problems
- The cost of genetic testing is high, and most of them are not covered by insurance.
- Genetic testing can lead to anxiety and distress. that is the reason why genetic testing should not be done without genetic counselling.
- Gentic testing should not be advised by parents to their offspring as it is an indivuals own choice to know about their genes.
FAQs
Q.1 Why is genetic testing important?
Genetic testing can help to identify whether or not you are at increased risk for developing breast cancer.
Q.2 How do I prepare for genetic testing?
If you are considering undergoing genetic testing or brca testing, it is important to speak with your doctor about the risks and benefits of the test. You should also ask your doctor if there is anything you need to do to prepare for the test.
Q.3 What can I expect during genetic testing?
The specific steps involved in genetic testing will vary depending on the type of test you are undergoing. However, in general, you can expect to provide a blood or saliva sample, which will be analyzed for the presence of certain mutations.
Q.4 What happens after I receive my results?
If you undergo genetic testing and receive positive results, it is important to speak with Dr. Shilpy Dolas about what this means for your health and your risk of developing breast cancer. Additionally, you may want to consider preventative mastectomy or oopherectomy if brca results are poistive to take call on your results and make decisions about your health.
