Advanced Cancer Testing
Modern cancer care is rapidly evolving. Today, functional testing offers new insights into how cancer behaves at a cellular and genetic level, helping you and your care team make more personalized decisions.
RGCC International offers advanced testing for cancer patients for early detection and to better refine treatment.

R.G.C.C. International Cancer Tests
RGCC International (Greece) provides world-leading tests capable of identifying potential early signs of cancer, monitoring diagnosed cancers, and offering personalized guidance on the most effective combinations of cancer treatments and therapies, including complementary approaches.
What they Measure
Their Liquid Biopsy Tests provide a comprehensive evaluation of different types of biomarkers in the blood, including circulating tumour DNA, cell-free RNA, proteins and circulating tumour cells. Liquid biopsies can provide information about the presence of cancer, genetic changes in the body, the effectiveness of treatment and the progression of the disease.
Some key RGCC tests include:
Onconomics Plus: Assesses sensitivity of detected tumour cells to multiple chemotherapy agents, targeted therapies, and natural compounds—helping to personalize treatment choices.
Onconomics Extracts: Focuses on how tumour cells respond to specific plant-based and natural agents, aiding integrative care planning.
Oncotrail RGCC: Monitors CTC numbers and types in confirmed cancer (e.g. breast, colon, lung, melanoma, prostate, sarcoma), offering guidance on relapse risk and ongoing treatment effectiveness.
Who Benefits?
Functional cancer tests may help people who:
Are currently receiving cancer treatments and wish to personalize their supportive care plan.
Have completed treatment and want to monitor for recurrence or ongoing risk.
Have a strong family history or genetic predisposition.
Are seeking evidence-based integrative strategies that complement medical care and provide reassurance.
Why RGCC is Useful:
RGCC tests offer a validated scientific window into tumour biology. Sensitivity and specificity rates for circulating tumour cell (CTC) assays range from 86%–87% and 83%–84% respectively, subject to cancer type and clinical context. These results don’t replace conventional diagnosis or imaging, but can provide valuable additional insights for treatment personalization and emotional peace of mind.
All results are thoroughly reviewed—combining conventional medical perspectives with holistic strategies for strength, resilience, and wellbeing.
Sample: Blood draw, processed via NutriPath approved pathology lab in Australia, and sent to RGCC International.
Turnaround Time: 4–5 weeks
Lab Accreditation: RGCC labs meet IAS accreditation standards for technical and ethical reliability.

Your Cancer Testing Questions Answered
-
What is the difference between natural cancer support and cancer treatment?
Cancer treatment aims to control or remove cancer through medical interventions such as surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy or hormone therapy. Natural or integrative support aims to help you manage symptoms, maintain nutrition and strength, support sleep and emotional wellbeing, and improve quality of life alongside your medical plan.
“My work is about helping you feel informed, emotionally supported and as physically well as possible, through your treatment and recovery,. Supporting your health through this delicate process helps you to get the best possible outcomes” - Catrina Bleicher, Naturopath (BHSc), Essencia Wellbeing.
-
Will my oncologist accept or use RGCC test results?
Oncologists vary in their familiarity with RGCC and in whether they consider its findings useful for treatment decisions. Standard pathology, imaging, tumour markers and evidence-based oncology guidelines remain the basis for conventional cancer treatment decisions. RGCC results are best treated as supplementary information, not as a replacement for these established tools.
“With your consent, I can prepare a clear summary of relevant findings and the questions they raise, so you can discuss them constructively with your oncology team.” - Catrina Bleicher, Naturopath (BHSc), Essencia Wellbeing.
-
Can I take supplements, herbs or natural compounds while receiving cancer treatment?
Sometimes, but never assume that “natural” means safe during cancer treatment. Some supplements and herbal medicines can affect drug metabolism, blood clotting, immune activity, radiation sensitivity or the intended effect of chemotherapy, immunotherapy and targeted medicines.
“I review every supplement, herb and over-the-counter product you use against your treatment schedule and medications for potential interactions. Many natural remedies will need to pause during your medical treatment phases” - Catrina Bleicher, Naturopath (BHSc), Essencia Wellbeing.
-
Can I use naturopathic support during chemotherapy, radiotherapy, immunotherapy or targeted therapy?
Yes, provided it is planned carefully and coordinated with your oncology care. Supportive naturopathic care may focus on nutrition, appetite, digestion, sleep, fatigue, stress, movement and emotional wellbeing, while avoiding products or doses that could interfere with your treatment.
“Cancer care is never the place for a generic supplement protocol. I review your diagnosis, medicines, treatment schedule and blood results before recommending anything, and adjust the plan as your treatment changes.” - Catrina Bleicher, Naturopath (BHSc), Essencia Wellbeing.
-
How much does RGCC testing cost, and how long do results take?
The cost depends on the specific RGCC panel and whether more than one test is appropriate. Testing is a separate laboratory expense in addition to consultation fees.
Results are usually available in approximately 4–5 weeks after the blood sample is collected and received by the laboratory. We discuss expected costs before proceeding and can consider whether testing needs to happen now or whether it makes more sense to begin with supportive care first.
-
How could RGCC results change my naturopathic support plan?
Results may help us refine your plan, rather than replace the foundations of good cancer support. For example, an Onconomics panel may inform a more focused discussion about which natural compounds should be prioritised, avoided or reviewed with your oncology team. Oncotrail may provide additional monitoring information to discuss in the context of your existing medical follow-up.
“My role is to translate complex information into a practical, safety-first plan: what is useful now, what needs discussion with your oncologist, and what is not worth adding.” - Catrina Bleicher, Naturopath (BHSc), Essencia Wellbeing.
Nutrition, symptom support, sleep, movement, stress care and medication safety remain important whether or not you proceed with testing.
-
What can RGCC cancer tests tell me, and what can’t they tell me?
RGCC liquid-biopsy panels analyse biomarkers in a blood sample, such as circulating tumour cells and tumour-related genetic material. Depending on the panel, they may provide information relevant to tumour-cell characteristics, circulating tumour-cell monitoring or laboratory responses to selected drugs and natural compounds. Liquid biopsy is an emerging area of oncology that may provide additional information about a cancer’s biology and, in some settings, help clinicians consider treatment options.
However, these tests cannot diagnose every cancer, rule out cancer, guarantee which treatment will work, or predict an individual outcome. Results must be interpreted alongside your pathology, scans, tumour markers and oncology advice.
-
Is RGCC cancer testing appropriate for me?
RGCC testing may be worth considering if you have a confirmed cancer diagnosis and want additional information to help refine an integrative support plan. It may also be relevant during or after treatment when discussing monitoring with your medical team.
“Before I recommend any test, I look at what you are hoping it will change. If the result is unlikely to alter your next step, I will say so. The aim is not more testing, it is more useful information.” - Catrina Bleicher, Naturopath (BHSc), Essencia Wellbeing.
Suitability depends on your cancer type, stage, current treatment, medical history, budget and the role your oncologist sees for additional testing.
