Question: Is there genetic testing available for the breast cancer gene?

Is genetic testing for breast cancer worth it?

Generally speaking, genetic testing is quite accurate at detecting known genetic variants. But these tests cannot tell you whether you’ll eventually develop breast cancer. Receiving a positive result means that, compared to the general population, you’re at an increased risk of developing breast cancer.

What age can you be tested for breast cancer gene?

Once a BRCA1/2 or other high-risk inherited gene mutation is found, genetic testing is available to family members who are age 18 or older. If you have a high-risk gene mutation, your children have a 50 percent (1 in 2) chance of having the same mutation.

Can breast cancer genes skip a generation?

If you have a BRCA mutation, you have a 50 percent chance of passing the mutation to each of your children. These mutations do not skip generations but sometimes appear to, because not all people with BRCA mutations develop cancer. Both men and women can have BRCA mutations and can pass them onto their children.

How do you get tested for the BRCA gene?

To test for a hereditary BRCA mutation, your doctor or genetic counselor will collect a blood or saliva sample to test your DNA. This sample will be sent to a lab where a technician will look for mutations in your DNA. The lab will then report the results to your doctor or genetic counselor.

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.

Is genetic breast cancer curable?

FRIDAY, Jan. 12, 2018 (HealthDay News) — Young breast cancer patients with a BRCA gene mutation have the same chances of survival after treatment as those without the mutation, a new study finds. BRCA mutations are inherited and increase the risk of breast and ovarian cancers.

Are you more likely to get breast cancer if your mother has it?

A woman’s risk for breast cancer is higher if she has a mother, sister, or daughter (first-degree relative) or multiple family members on either her mother’s or father’s side of the family who have had breast or ovarian cancer. Having a first-degree male relative with breast cancer also raises a woman’s risk.

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.

Can I have the BRCA gene if my mom doesn t?

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.

Is breast cancer passed through mother or father?

About 5% to 10% of breast cancer cases are thought to be hereditary, meaning that they result directly from gene changes (mutations) passed on from a parent.

What are the chances of getting breast cancer if your sister has it?

And just as significant is the fact that women with a first-degree relative (mother, sister, daughter, aunt, etc.) who developed breast cancer have a risk that is about double an average woman’s risk, or a 24% chance of getting it.
