Summary: Breast cancer could be detected up to five years before there are any clinical signs of it, using a blood test that identifies the body’s immune response to substances produced by tumor cells, according to new research.

When to take a blood test for breast cancer?

Blood marker tests may be done before treatment, to help diagnose the breast cancer and determine whether it’s moved to other parts of the body; during treatment, to assess whether the cancer is responding; and after treatment, to see if the cancer has come back (recurrence).

Can a BRCA gene test tell if you have breast cancer?

The BRCA gene test is offered only to people who are likely to have an inherited mutation based on personal or family history, or who have a specific type of breast cancer. The BRCA gene test isn’t routinely performed on women at average risk of breast and ovarian cancers. A BRCA gene test determines whether you carry an inherited BRCA mutation.

Can a genetic test tell if you have breast cancer?

Which is an example of a blood marker for breast cancer?

Examples of markers your doctor may test for include: CA 15.3: used to find breast and ovarian cancers. TRU-QUANT and CA 27.29: may mean that breast cancer is present. CA125: may signal ovarian cancer, ovarian cancer recurrence, and breast cancer recurrence.

Can a family member be tested for breast cancer?

Whenever possible, the first person tested in your family should be someone who has had breast, ovarian, or another BRCA -related cancer. If none of your family members who have had one of these cancers are available for genetic testing, then genetic testing can start with an unaffected person. However, the test results might not be as helpful.

What happens when a breast cancer blood marker test comes back negative?

While breast cancer blood marker tests are promising, they’re not absolutely conclusive. When a breast cancer blood marker test comes back negative, it doesn’t necessarily mean you’re free and clear of breast cancer. And a positive result doesn’t always mean that the cancer is growing.

Who is the first person to be tested for breast cancer?

The genetic counselor can help you determine the best testing strategy for you and your family. Whenever possible, the first person tested in your family should be someone who has had breast, ovarian, or another BRCA -related cancer.
