What Is a Tumor-Related Gene? How RGCC Gene Expression Testing Helps Personalize Cancer Treatment
When you're facing cancer, one of the biggest challenges is knowing which treatment is right for you. Every person’s cancer is different, and that’s why the same treatment doesn’t work for everyone. That’s where tumor-related gene expression testing from RGCC comes in.
This advanced test analyzes your cancer at the genetic level. It reveals which tumor-related genes are overactive and which may be influencing how fast your cancer grows or spreads. Once we understand that, we can choose treatments that are more targeted—and likely more effective.
What Is a Tumor-Related Gene?
A tumor-related gene is a gene that plays a role in cancer development. Some genes make cancer cells grow, divide, or spread faster. Others help tumors resist treatment or make new blood vessels (a process called angiogenesis) to keep feeding the cancer.
RGCC’s gene expression testing measures how much these genes are “turned on” or overexpressed. If a gene is highly overexpressed, it’s likely playing a big role in the cancer’s behavior.
Knowing which genes are active allows your care team to block those genes using drugs, supplements, or natural therapies. That’s the power of personalization—and why this test matters so much.
How Does RGCC Tumor-related Gene Expression Testing Work?
RGCC uses a specialized lab technique called transcriptomic microarray testing. It starts with a simple blood draw—no surgery or invasive procedure needed. The blood sample is sent to the lab where they:
Isolate circulating tumor cells (CTCs) – These are cancer cells that have broken away from a tumor and are floating in the blood.
Destroy the CTCs to extract their mRNA (the gene expression blueprint).
Reverse transcribe the mRNA into DNA to measure which genes are turned on or off.
Use microarray technology to assess gene activity—specifically looking at over 90 tumor-related genes.
The final report shows which genes are overexpressed, which are underexpressed, and how strongly they’re active. The higher the percentage of expression, the more influence that gene has on the cancer.
Why Is This Important for Treatment?
There are two major benefits to knowing your tumor-related gene expression:
Identifying Drug Targets – Some genes are linked to specific drugs that can block or turn them off. These are called “druggable targets.”
Understanding What Drives the Disease – Highly active genes may be pushing the cancer to grow faster. Targeting these first can slow down or stop progression.
For example, if a gene involved in new blood vessel growth (like VEGF) is overexpressed, a therapy that blocks VEGF might be included in your plan. If hormone receptor genes (like estrogen or progesterone receptors) are overactive, hormone therapy may be an option.
How RGCC Results Expand Your Treatment Options
RGCC’s tumor-related gene report adds an extra layer of detail on top of its chemosensitivity test (which shows which therapies kill cancer cells best). The gene expression results help:
Reveal more treatment options beyond the 170+ substances tested in the chemosensitivity panel.
Guide which natural substances or supplements might be useful for your case.
Support long-term planning by monitoring how your cancer changes over time.
Even if a therapy didn’t score well in the chemosensitivity test, if the gene it targets is overexpressed, it may still be helpful—especially when paired with other agents.
The Value of Ongoing Testing
Cancer changes. What worked three months ago might not work today. Gene expression testing allows us to watch those changes.
At WellSpot IV, we often recommend repeating RGCC Tumor-related Gene Expression testing every 9 to 12 months. This helps track:
Which genes are becoming more active
Which ones are calming down
How treatments are working over time
This makes it easier to adjust your protocol before problems arise. And the goal is always the same: fewer cancer cells, lower risk of metastasis, and more time in remission.
What If You Don’t Have This Info?
Without gene expression testing, you’re relying mostly on trial-and-error. That can lead to delays, side effects, and wasted treatments.
The RGCC test helps answer questions like:
Why is my cancer not responding?
Is there a better option?
What can I do if I’ve run out of standard treatments?
It brings clarity and confidence—so you and your care team can move forward with a plan that fits your body, not someone else’s.
What About Hormone Receptors and Subtypes?
Gene expression testing can also show your hormone status—like estrogen, progesterone, and HER2 receptors. This is especially helpful if:
You never had a tissue biopsy
Your original test didn’t include receptor status
Your cancer has changed over time
Interestingly, RGCC sometimes finds differences between the tissue biopsy and what’s in your blood. That’s because tumors are made of different subpopulations. Some cells may be hormone-positive, others not. This gives you a bigger picture of what’s happening—and helps guide better choices.
