Understand RGCC Genetic Cancer Testing: A Personalized Approach to Cancer Care
At Natural Medicine Center, we are committed to offering innovative tools that can help patients and their healthcare teams make more informed decisions. That’s why we’re excited to offer RGCC (Research Genetic Cancer Centre) testing—an advanced laboratory analysis that provides personalized insights into an individual’s cancer biology through a simple blood draw.
While RGCC testing is not a replacement for conventional oncology care, it can provide valuable supplemental information that may help guide a more individualized treatment approach.
What is RGCC Testing?
RGCC is an internationally recognized laboratory specializing in the analysis of circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) found in the bloodstream.
Unlike traditional biopsies, which examine tissue from one location, RGCC evaluates living cancer cells that have entered the bloodstream. This allows clinicians to gain insight into how cancer may be behaving throughout the body at the time of testing.
Using a simple blood sample, RGCC testing can:
- Detect circulating tumor cells (CTCs)
- Analyze the genetic characteristics of cancer cells
- Evaluate how aggressive the cancer may be
- Identify targeted therapies that may be more effective
- Assess laboratory sensitivity to certain natural compounds and nutraceuticals
- Monitor changes in circulating tumor cells over time
Because every patient’s cancer is biologically unique, this information may help healthcare providers personalize treatment recommendations.
Important: RGCC results should always be interpreted by a qualified healthcare provider and used alongside standard medical evaluation.
What Does the Testing Process Look Like?
The process is straightforward:
- Blood Collection – A blood sample is collected at our office.
- International Laboratory Analysis – The sample is carefully shipped to the RGCC laboratory, where specialized testing is performed on circulating tumor cells and circulating tumor DNA.
- Comprehensive Report – Several weeks later, a detailed report is returned with information about the biology of the cancer cells.
- Provider Consultation – Your healthcare provider reviews the findings and discusses how the information may fit into your overall treatment plan.
Many patients also choose to repeat testing over time to help monitor changes in circulating tumor cells while undergoing treatment.
What Information Can the Report Provide?
Depending on the test ordered, an RGCC report may include information such as:
- The number of circulating tumor cells detected
- Genetic characteristics of those cancer cells
- Biomarkers associated with tumor behavior
- Potential sensitivity to certain chemotherapy agents (laboratory testing only)
- Potential laboratory sensitivity to selected natural compounds and nutraceuticals
- Trends that may help monitor treatment response over time
It is important to remember that these laboratory findings are not guarantees of clinical response. Rather, they provide additional data that physicians may consider when making treatment decisions.
An Example of Personalized Recommendations
One patient who underwent RGCC testing received a report showing detailed information about circulating tumor cells and tumor markers. Based on the laboratory findings, the report suggested areas for discussion with the patient’s healthcare team, including:
- Which chemotherapy agents demonstrated stronger laboratory activity against that patient’s circulating tumor cells.
- Which medications appeared less active in the laboratory setting.
- Several nutritional compounds that showed laboratory sensitivity, including compounds such as vitamin C, curcumin, lycopene, apigenin, CoQ10, and mushroom-derived extracts, introduced in a staged supplementation schedule.
- Lifestyle considerations such as reducing excess sugar intake and encouraging healthy nutrition and exercise.
- Recommendations for ongoing monitoring as treatment progressed.
These recommendations were personalized to that individual’s laboratory results and should never be generalized to all patients. Every RGCC report is unique because every person’s cancer biology is different.
Who May Benefit?
RGCC testing may be beneficial for:
- Individuals with a current cancer diagnosis
- Patients seeking a more personalized treatment approach
- Those interested in integrative oncology
- Individuals looking for additional information alongside conventional testing
- Patients wishing to monitor treatment response over time
What Patients Appreciate About RGCC
Many patients appreciate that RGCC offers information that goes beyond imaging studies or routine blood work.
One patient testimonial shared on the RGCC International website states:
“RGCC testing gave us additional information that helped us have a more informed discussion with our medical team and feel more confident about our treatment decisions.”
While individual experiences vary and no specific outcome can be guaranteed, many patients value having additional biological information available when discussing treatment options with their oncology providers.
A Supplemental Tool—Not a Replacement
RGCC testing is designed to complement, not replace:
- Oncology care
- Pathology
- Imaging studies
- Standard laboratory testing
- Physician recommendations
Natural Medicine Center recommends RGCC as a supplemental testing tool for patients who are already under the care of an oncologist or cancer specialist.
