Question 1

What is RGCC testing?

Accepted Answer

RGCC (Research Genetic Cancer Centre) is an international laboratory specializing in liquid biopsy and genomic cancer testing. RGCC blood tests analyze circulating tumor cells (CTCs) and circulating tumor DNA from a simple blood draw to support early cancer detection, treatment personalization, and ongoing monitoring. Newport Integrative is an RGCC network partner offering these tests in Orange County.

Question 2

What is a liquid biopsy blood test for cancer?

Accepted Answer

A liquid biopsy is a blood test that detects cancer cells and tumor DNA circulating in the bloodstream. Unlike a traditional tissue biopsy, it requires only a blood draw and can detect cancer at its earliest stages, monitor treatment response, and detect recurrence — all from a single sample. RGCC combines liquid biopsy with genomic profiling for clinically actionable insights.

Question 3

What cancers can the RGCC liquid biopsy detect?

Accepted Answer

RGCC liquid biopsy is used for solid tumors (breast, colorectal, prostate, ovarian, pancreatic, liver, stomach, esophageal, bladder) and is well-established for blood cancers (leukemia, lymphoma, myeloma), where cancer cells naturally circulate. It monitors treatment response, tracks metastasis, and assesses genetic changes over time.

Question 4

How is RGCC different from standard cancer screening?

Accepted Answer

Standard screening (imaging, tumor markers) typically detects cancer only after a tumor has grown large enough to be visible. RGCC liquid biopsy detects circulating tumor cells and tumor DNA at the molecular level — often before symptoms or imaging findings appear — and profiles the tumor's specific genetic characteristics to guide personalized therapy rather than one-size-fits-all treatment.

Question 5

How does RGCC personalize cancer treatment?

Accepted Answer

RGCC genomic profiling reveals tumor-specific mutations and chemosensitivity, guiding targeted therapy selection. By identifying which treatments your particular cancer is likely to respond to, RGCC helps avoid ineffective therapies and side effects, supporting precision oncology. Serial testing tracks response and adapts strategy in real time.

Question 6

Is RGCC testing covered by insurance?

Accepted Answer

RGCC testing is typically cash-pay and not submitted to insurance, which keeps the genomic analysis comprehensive and unrestricted by insurer limitations. We recommend discussing cost and clinical appropriateness during a consultation. RGCC tests complement — but do not replace — standard oncology care and imaging.
