RGCC Testing — A New Way to Understand and Navigate Cancer Treatment
RGCC Testing — A New Way to Understand and Navigate Cancer Treatment
In today’s world of precision medicine, our ability to understand cancer has gone far beyond what imaging and tumour markers alone can tell us. At Healthrenew Clinic, we work with both conventional oncologists and integrative medicine practitioners to bring our patients the most advanced diagnostic tools available.
One such tool is the RGCC test — developed by Research Genetic Cancer Centre International (RGCC) in Switzerland. RGCC specializes in advanced biotechnological testing, particularly in analysing circulating tumour cells (CTCs) and gene expression profiles in a simple blood sample.
What makes RGCC unique is its ability to capture and analyse live cancer cells from the bloodstream, giving doctors valuable insight into how a cancer behaves, how it responds to treatment, and what therapies — conventional or natural — are most likely to work for that specific patient.
Who Should Consider the RGCC Test?
Over the years, I’ve found that RGCC testing can be especially helpful for several groups of patients:
1. Patients currently on treatment or who have completed therapy
For patients undergoing chemotherapy, radiotherapy, or targeted treatments, RGCC offers a way to measure how well their body is responding. By monitoring the number and characteristics of circulating tumour cells, we can get a clearer picture of whether the treatment is working — something that scans alone may not always show. This information can help doctors decide whether to continue, adjust, or change the treatment plan.
2. Individuals with a strong family history of cancer
Some people carry a genetic or familial risk of cancer but have no symptoms and normal scans. In such cases, RGCC testing can detect early warning signs — such as the presence of CTCs or changes in gene expression within immune cells (PBMCs). This allows for better risk stratification and opens the door to proactive, preventive strategies — long before conventional tests can pick up disease.
3. Patients pursuing integrative or natural approaches
For patients who choose to combine or replace conventional treatment with natural or metabolic oncology approaches — such as repurposed medications, hyperthermia, high-dose vitamin C, or B17 infusions — RGCC provides a scientific foundation to guide their choices. The Onconomics Extracts test, for example, evaluates how your actual cancer cells respond to a wide range of natural substances and repurposed drugs. This helps remove the guesswork and ensures that your integrative treatment plan is evidence-based and individualized.
Not a Replacement — But a Valuable Companion
One of the biggest misconceptions is that RGCC testing competes with conventional oncology. In truth, it complements it. RGCC does not replace chemotherapy, surgery, or radiotherapy. Instead, it provides a scientific dashboard — additional layers of information that help doctors and patients see the bigger picture.
Cancer care shouldn’t depend solely on whether a scan looks clear or not. Healing involves rebuilding and retraining the immune system to keep us cancer-free for the long term. If we’re going to use nutrition, supplements, or natural therapies, it only makes sense to first identify which ones have been shown to work against your specific cancer profile.
This is where RGCC excels — helping both doctors and patients make informed, measurable decisions. For advanced integrative oncology practitioners, RGCC also opens the door to more targeted therapies such as QREstrain, dendritic cell therapy, or cancer vaccines, which can be tailored according to the patient’s cancer genomics and proteomics data.
A Better Way to “Drive” Through Cancer Treatment
I often explain RGCC to patients using this analogy:
Treating cancer without RGCC data is like driving an older car without a dashboard or GPS. You can still get to your destination, but you’ll rely mostly on experience, instinct, and luck.
With RGCC, it’s like upgrading to a modern vehicle — one with a digital cockpit, fuel efficiency monitors, real-time maps, warning sensors, and surround cameras. It doesn’t make the driver any less skilled; it simply makes the journey safer, smoother, and more predictable.
Even the most experienced driver would appreciate knowing what’s ahead, especially when navigating unfamiliar terrain. The same applies to cancer care. RGCC provides the visibility and precision we’ve been missing.
How We Use RGCC at Healthrenew Clinic
At Healthrenew Clinic, we integrate RGCC testing into our holistic, evidence-based approach. For suitable patients, we arrange the test in collaboration with RGCC’s international laboratory network and help interpret the results alongside your oncology or integrative care plan.
We typically recommend RGCC testing:
- During or after conventional treatment to assess response
- For high-risk but asymptomatic individuals
- For patients pursuing integrative or personalized oncology
Follow-up testing may be done every few months to monitor changes, track remission, or guide therapy adjustments.
Our goal is not to replace your oncologist but to empower you and your care team with deeper, more personalised information — helping you make choices that are both scientifically guided and uniquely suited to your biology.
Final Thoughts
Modern medicine is rapidly moving towards precision oncology — and RGCC is one of the pioneers leading that shift. By analysing how your actual cancer cells behave, RGCC helps bridge the gap between conventional oncology and integrative, immune-supportive care.
At the end of the day, this test is not about choosing one path over another — it’s about combining the best of both worlds to give you a clearer direction, stronger guidance, and a better fighting chance.
Disclaimer: RGCC tests are diagnostic tools designed to provide additional insights for clinical decision-making. They should always be interpreted by qualified healthcare professionals in conjunction with standard medical evaluations and treatments.
