Your Cancer is Unique.
Your Treatment Should Be Too.

Standard cancer guidelines follow a statistical manual.

RGCC follows your biology.

We capture Circulating Tumor Cells (CTCs)—the living "seeds" of your cancer—and test them against drugs in the laboratory to find what actually destroys them.

We Don't Predict. We Test.

Most tests read the DNA "blueprint" to predict what might work for your cancer. We stress-test live cells to see what actually works.

Where Are You in Your Journey?

I Want Personalised Care

For patients seeking data-driven drug selection (Chemo & Natural) or those who have failed first-line therapy.

I Want Ultra-Early Detection

For healthy individuals seeking deep screening beyond standard imaging.

I'm in Remission

For patients who have finished treatment and want to ensure no "Silent Seeds" (Stem Cells) remain.

Our Solutions

Pre-Screen: Catch the Crisis Before it Begins.

A tumor typically grows silently for years, reaching 1 billion cells (approx. 1cm) before cancer risk detection tests detects it.


Our Solution: RGCC's early cancer risk screening catches diseases in the "Silent Phase", long before they become a visible crisis.

Cancer Care: Stop Guessing. Start Testing.

Standard cancer treatment tests rely on statistics to predict your drug response.


Our Solution
: A non-invasive liquid blood test that exposes your live cancer cells to 50+ chemotherapy drugs, 50+ targeted agents, and 50+ natural substances, helping your physician shape a personalised cancer care plan.

Remission: Seek out "Silent" Survivors.

In Standard PET/CT scans, a tumour only becomes visible after growing to approx. 5mm (millions of cells).

Our Solution
: Instead of dead DNA fragments that only show what the treatment killed, we search for surviving Cancer Stem Cells - the "Mother Cells" responsible for relapse.

Everything we do at RGCC is keeping only one person in the mind: the patient

Every human is not identical. Why should their cancer be identical? Why should every person be treated in the same manner, with the same treatment?
