What's this test for?

This test is ideal if you've been diagnosed with breast cancer and need to find out whether HER2-targeted therapy could work for you. It looks closely at your tumor tissue to see if the HER2 gene is making too many copies of itself, which affects how the cancer grows and which treatments are likely to help. This information is a key part of building a treatment plan after a breast cancer diagnosis.

What's included in this test?

This test uses a technique called FISH to look directly at the HER2 gene inside your tumor cells and count how many copies are present. If the FISH result is inconclusive, the same tissue sample is automatically checked with a second method (IHC) that measures the HER2 protein on the cell surface. Together these two approaches give a more complete and reliable picture of your tumor's HER2 status.

What happens after I get my results?

Your results will show up in your account along with an explanation of what the HER2 finding means for your specific report. If the initial FISH result comes back unclear, the lab automatically runs a follow-up IHC test on the same sample so you get a definitive answer without needing a new specimen. You can download the full lab report from your account at any time, and because this is typically a one-time diagnostic test tied to a specific tumor sample, retesting is usually only needed if a new biopsy is taken. If your results raise questions about next steps, treatment planning should happen promptly given the nature of a cancer diagnosis.

How can I naturally support treatment outcomes during breast cancer care?

While no lifestyle change can substitute for appropriate cancer treatment, staying active, eating a balanced diet rich in fruits and vegetables, and getting enough sleep can help your body handle treatment better. Reducing alcohol intake and avoiding smoking are also linked to better outcomes in breast cancer patients. Managing stress through gentle activities like walking, meditation, or support groups can also make a meaningful difference during this time.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. If your case requires the additional IHC reflex test due to an inconclusive FISH result, it may take a little longer since that second test is run on the same tissue sample. You'll be notified as soon as your full report is available in your account.

Who should consider this test?

Anyone recently diagnosed with breast cancer should consider this test, since HER2 status is a standard part of understanding a new breast cancer diagnosis. It's especially relevant if a treatment plan involving HER2-targeted therapy is being considered. Because HER2 status affects treatment options, testing is recommended for essentially all newly diagnosed invasive breast cancer cases.

What does a positive (amplified) HER2 result mean?

A positive or amplified result means your tumor cells have extra copies of the HER2 gene, causing them to produce more HER2 protein than normal. This type of cancer, sometimes called HER2-positive, tends to grow faster than HER2-negative cancers but often responds well to HER2-targeted therapies. Knowing this status helps guide which treatments are likely to be most effective for your specific cancer.

What does a negative (non-amplified) HER2 result mean?

A negative result means your tumor does not have extra copies of the HER2 gene, so it's classified as HER2-negative. This means HER2-targeted therapies are not expected to be effective, and other treatment approaches will be more appropriate. Your full report will explain exactly where your result falls and what it means for treatment planning.

What causes HER2 gene amplification in breast cancer?

HER2 amplification happens due to a genetic change within the tumor cells themselves, not something caused by diet, lifestyle, or environment. It occurs in up to 20% of primary breast cancers and is a random mutation that happens as cells divide and grow abnormally. It's not something you did or could have prevented, and it's not passed down through families in most cases.

What should I do if my results show HER2 amplification?

If your results show HER2 amplification, the next step is typically discussing HER2-targeted therapy options as part of your overall treatment plan. It also helps to talk through the full lab report so you understand exactly what your numbers mean. Keeping a copy of your results and tracking any future related testing over time can help keep your care organized.
