What's this test for?

This test is ideal if you're working through a cancer diagnosis and need more information about how a tumor is behaving. Ki-67 is a special stain applied to a tissue sample that helps show how quickly the cells in a tumor are growing and dividing. It's typically used alongside other diagnostic steps to better understand a specific mass or biopsy sample.

What happens after I get my results?

Your results will be available in your account, and because this is a specialized tissue stain, the report is provided without an included interpretation. The report is downloadable directly from your account so you can keep a permanent copy for your records. If you're tracking a tumor or lesion over time, you can use the trends feature to keep all your related test results organized in one place. Because this result requires context from the original tissue sample and biopsy findings, take dangerous or unclear findings seriously and seek medical care promptly.

Who should consider this test?

This test is generally considered by people who already have a tissue biopsy or surgical sample that needs further evaluation. It's often used for people newly diagnosed with a tumor, or those monitoring a known growth to understand how aggressively it may be behaving. It's typically ordered as a follow-up step rather than a first-line screening test.

What symptoms indicate I may need this test?

You may consider this test if you've already found a lump, mass, or abnormal growth through imaging or a physical exam and a tissue sample has been collected. Symptoms like unexplained swelling, a growing lump, or unusual changes in a mole or tissue area are often what lead someone to this point. This test itself doesn't diagnose symptoms — it's used on tissue that's already been removed or biopsied.

What is Ki-67 and why does it matter?

Ki-67 is a protein found inside actively dividing cells, so pathologists use it as a marker to estimate how fast a tumor's cells are multiplying. A higher percentage of Ki-67-positive cells generally suggests faster-growing tissue, while a lower percentage suggests slower growth. This information helps piece together the bigger picture of a tumor's behavior alongside other tissue findings.

How can I naturally support my body during cancer monitoring?

While no lifestyle change replaces medical treatment, eating a balanced diet with plenty of vegetables, lean protein, and whole grains supports your body's overall resilience. Staying physically active, prioritizing sleep, and managing stress through activities like walking or meditation can help you feel your best during this time. Avoiding tobacco and limiting alcohol are also widely recommended supportive steps.

How often should I retest?

Retesting frequency for Ki-67 depends on the specific tissue or tumor being monitored and isn't something done on a fixed schedule like routine bloodwork. It's typically repeated only if a new biopsy or surgical sample is taken, such as after treatment or if a growth changes. Because this is a specialized diagnostic tool, timing is usually guided by your overall treatment plan rather than routine intervals.

What should I do if my results are concerning?

If your Ki-67 result shows a high percentage of dividing cells, treat this as important information to act on quickly rather than wait. Bring your full report, including the original biopsy findings, to your next medical appointment so all the pieces can be reviewed together. If you experience new or worsening symptoms in the meantime, seek medical care right away.

What does a high Ki-67 percentage mean?

A high Ki-67 percentage means a larger share of the tumor's cells are actively dividing, which is generally associated with faster-growing, more aggressive tissue. This doesn't tell the whole story on its own — it's meant to be considered alongside biopsy type, tumor size, and other pathology findings. High results are typically a signal to move forward with timely follow-up care.

What does a low Ki-67 percentage mean?

A low Ki-67 percentage means fewer cells in the sample are actively dividing, which is often associated with slower-growing tissue. This can be a reassuring sign, but it still needs to be interpreted together with the rest of your pathology findings. Even low results are worth discussing further as part of your overall care plan.
