What's this test for?

This test is ideal if you or a lab already has a tumor tissue sample and need to know whether it contains progesterone receptors. It's most often used after a breast cancer diagnosis to help figure out which drug therapies are likely to work best. This test does not diagnose cancer itself — it's a follow-up test done on tissue that has already been biopsied or removed.

What's included in this test?

This test looks specifically at whether progesterone receptors are present on the surface of tumor cells taken from a tissue sample. Knowing whether these receptors are present matters because it helps determine whether hormone-based therapies could be effective, versus other treatment approaches. The test is performed using a lab technique called IHC (immunohistochemistry), which stains the tissue sample so the receptors can be seen and counted under a microscope.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative progesterone receptor result means for tissue behavior. Because this result guides treatment decisions rather than lifestyle changes, the most important next step is discussing the result with whoever is coordinating your cancer treatment plan. You can download the full lab report from your account at any time, and if repeat testing is ever needed on a new sample, you'll be able to track results over time using the trends feature.

How can I naturally support hormone-sensitive tissue health?

While this test result itself needs to be interpreted alongside a treatment plan, some everyday habits support overall hormone balance and tissue health. Eating a diet rich in vegetables, fiber, and lean protein, staying physically active, limiting alcohol, and maintaining a healthy weight are all linked to better hormone-related health outcomes. These habits are supportive, not a replacement for the treatment plan built around your test results.

When will I get my results?

Results for this test are typically ready within about 7 days of the lab receiving your tissue sample. This turnaround allows time for the tissue to be properly processed, stained, and examined under a microscope by lab specialists. You'll receive a notification as soon as your results are posted to your account.

Who should consider this test?

This test is generally considered for people who have already had a tumor biopsy or surgical tissue removed, most commonly related to breast cancer. It's typically ordered as part of a broader diagnostic workup rather than as a standalone screening test. If a biopsy or tissue sample has been collected and treatment planning is the next step, this test may be relevant.

What does a positive progesterone receptor result mean?

A positive result means the tumor cells have progesterone receptors, which suggests the tumor's growth may be influenced by hormones. This is generally considered useful information because it means hormone-based therapies may be an effective part of the treatment approach. Your full report will explain the percentage of cells that tested positive, which adds more detail to this picture.

What does a negative progesterone receptor result mean?

A negative result means the tumor cells did not show progesterone receptors, which suggests hormone-based therapies are less likely to be effective for that particular tumor. This usually means other treatment approaches will be considered instead. The report will provide more context on what this finding means for the specific tissue sample tested.

How often should I retest?

This is not a routine or repeat screening test — it's typically done once on a specific tissue sample. Retesting would only happen if a new tumor sample is collected, such as after a recurrence or a new biopsy. There's no general retesting schedule the way there is with routine bloodwork.

What should I do if my results are unclear or need more context?

If your report or results raise questions, keep the downloadable lab report handy since it contains detailed notes from the lab specialist who reviewed your tissue sample. Review the interpretation section carefully, since receptor testing includes detail like percentage of positive cells that adds nuance beyond a simple positive or negative label. Use this report as part of the bigger picture when discussing treatment options.
