Is genetic testing for breast cancer accurate?
Genetic testing is not 100% accurate. If a test is negative, a person still has a chance of getting breast cancer. If the test is positive, there is still a 15% to 20% chance of not getting breast cancer. Genetic testing is costly, ranging from about $400 to more than $3,000, depending on the type of test.
How much does the BRCA test cost?
The cost of BRCA gene mutation testing varies depending upon what lab is used, and how broad the test is. Some tests look only for a mutation known to run in your family. Others look for a much wider range of mutations. The cost of testing ranges from under $100 to over $2000.
What gene is more likely to get breast cancer?
BRCA1 and BRCA2: The most common cause of hereditary breast cancer is an inherited mutation in the BRCA1 or BRCA2 gene. In normal cells, these genes help make proteins that repair damaged DNA. Mutated versions of these genes can lead to abnormal cell growth, which can lead to cancer.
Is genetic cancer screening worth it?
Tests can lead to more tests: In some cases, more medical tests, cancer screenings, or procedures may have to be done as a result of genetic testing. This can be a good thing, if these other tests help keep you free of cancer or if they find it early, when it’s likely to be smaller and might be easier to treat.
What are the disadvantages of genetic testing?
Some disadvantages, or risks, that come from genetic testing can include:
- Testing may increase your stress and anxiety.
- Results in some cases may return inconclusive or uncertain.
- Negative impact on family and personal relationships.
- You might not be eligible if you do not fit certain criteria required for testing.
How long does genetic testing take for breast cancer?
Counselors can administer the test and properly interpret the results when they’re in — they take about three weeks. Genetic tests can be done in a primary-care doctor’s office.
What happens if you test positive for BRCA?
A positive test result means that you have a mutation in one of the breast cancer genes, BRCA1 or BRCA2, and therefore a much higher risk of developing breast cancer or ovarian cancer compared with someone who doesn’t have the mutation. But a positive result doesn’t mean you’re certain to develop cancer.
At what age should BRCA testing be done?
Although these measures are imperfect and not always acceptable, they do provide a means to reduce the cancer risks facing women with BRCA1 mutations [2-6]. Current practice standards recommend that these women start screening in early adulthood (25-35 years) .
Can I have the BRCA gene if my mom doesn t?
BRCA Inheritance: Are Your Family Members at Risk? Because BRCA mutations are hereditary, they can be passed down to family members regardless of gender. This means that if you have a BRCA mutation, you inherited it from one of your parents.
At what age is most breast cancer diagnosed?
The risk for breast cancer increases with age; most breast cancers are diagnosed after age 50.
What are the chances of breast cancer with no family history?
More than 75% of women with breast cancer have no family history of the disease and less than 10% have a known gene mutation that increases risk. If you have relatives who have had breast cancer, you may worry that you’re next.
