Personalized cancer journeys with RGCC
We are your powerful ally in the fight against cancer
At RGCC, we understand that every cancer journey is unique. Each patient reacts differently to standardized treatments, and each tumor should be assessed in a complex and comprehensive manner. Since 2004, we have specialized in cancer genetics, liquid biopsy testing, and chemosensitivity testing, supporting patients and healthcare providers worldwide. Our mission is simple: to help detect cancer earlier, monitor its progression, and support personalized cancer treatment plans tailored to each individual.
We work closely with healthcare providers from our network to analyze blood samples using advanced diagnostic technologies, delivering insights that can support cancer detection, diagnosis, and treatment decisions. This empowers our healthcare partners to individualize your treatment and support you with data-driven guidance to find the cancer treatment plan that is the most effective for you throughout your personalized cancer journey.
What RGCC cancer tests can do for you
- Early cancer detection and screening
Our advanced Onco-D-Clare test helps identify potential early signs of cancer, including circulating tumor cells (CTCs) and cancer-related biomarkers in the blood.
- Cancer monitoring and disease progression
Liquid biopsy testing allows ongoing monitoring of cancer, helping your doctor track how your primary cancer and possible metastasis evolve.
- Chemosensitivity testing and integrative treatment approaches
We provide insights into how your cancer may respond to different chemotherapy drugs and natural supplements, supporting truly individualized and integrative cancer care.
Patients are at the core of everything we do. Learn about how our non-invasive diagnostic technologies can support you in your cancer journey.
CTC and liquid biopsy testing
Using a simple blood draw, our tests (sometimes referred to as Greek/Greece Tests) are non-invasive and patient-friendly, minimizing discomfort while providing powerful clinical insights. We specialize in testing circulating tumor cells (CTCs). A CTC test allows real time monitoring of your tumor and can help detect tumor spread and the risk of recurrence early. With the RGCC cancer blood tests we can not only evaluate data from the primary tumor but also from possible metastasis.
Through precision oncology and molecular diagnostics, we analyze tumor-specific and genetic characteristics to help clinicians move beyond a one-size-fits-all approach that may not always work for your cancer.
This means:
-
- More precise treatment strategies
- Improved patient safety
- Better-informed clinical decisions
