What makes one cancer patient different from another?

The complexity of cancer makes personalization vital to cancer treatment. We offer personalized care solutions to improve your outcomes.

Our personalized solutions

Tackling your cancer together

Discover the power of our non-invasive CTC blood tests, which provide real-time monitoring of your cancer status using liquid biopsies.

The detection and monitoring of CTC markers circulating in the blood are used for screening, prognosis, and predicting a patient’s response to specific types of therapy.

RGCC: a cut above the rest

Competition
May prioritize speed and cost over quality and patient focus.
Dedication to quality, patient-centric approach, and distinctive testing methodology, ensuring top-notch service.
Limited testing options, potentially lacking comprehensive coverage of the cancer journey.
Unique, all-inclusive testing for every cancer stage, from baseline to recurrence prevention, delivering clear, actionable information for consistent and cohesive care.
Generic, one-size-fits-all approach to cancer testing.
Testing tailored to each patient’s unique genetic makeup and physiology, focusing on the individual expression of cancer.
Use Positive Selection which targets only specific antigens, leading to an incomplete, potentially misleading CTC count.
Employs Negative Selection, ensuring a comprehensive count of circulating cancer cells instead of a partial count.
May sacrifice accuracy for faster and cheaper testing methods.
Prioritizes patient care and will not compromise on the quality of testing, even if it requires more time and effort. Ensures the most accurate and reliable information possible.

Frequently asked questions

How do I know what test is right for me?

All our accredited practitioners are trained to guide you through the testing options and will make recommendations that are right for you.

What if the treatment doesn't work for me?

The power of our monitoring tests is they give you a measure of whether a treatment option is working or not so you can change course if needed. Along with the Onconomics panels which provide information about personalized treatment options, you have information on options that may be more effective for you.

How often should I see my practitioner about my cancer?

Each patient is unique. How often you should see your practitioner must be decided in consultation with them after they have reviewed your case. Although this timing may vary based on factors such as treatment options, within our process, monitoring is recommended every 3 months with active cancer to monitor effectiveness of treatments, and every 6-12 months in remission to monitor for early signs of recurrence as part of your Recurrence Prevention Program.

I was in remission, why did my cancer come back?

Even when you receive the “all clear” from your Oncologist, there may be CSCs (Circulating Stem Cell-like Cells) also known as TICs (Tumor Initiating Cells) still active and in circulation but at a level below the sensitivity of standard-of-care monitoring tests, such as imaging and physiological cancer marker testing. 

This means active cancer cells may be present, but they cannot be detected via traditional means until the cancer has grown big enough to be detected again. This leaves you vulnerable and without treatment because in the standard-of-care model, if you can’t see it, you can’t treat it, enabling the cancer to come back.

TIC monitoring with our OncoTrace and OncoTrail allows you to monitor these cells on a microscopic level allowing you to continue care until these cells are no longer active or if in remission, allowing you to see new activity as soon as it starts.

Is cancer more aggressive when it returns?

Cancer is often more aggressive when there is a recurrence. This highlights the importance of having a Recurrence Prevention Program once the cancer has gone into remission or as part of your post-treatment aftercare. 

Standard-of-care monitoring tests are not sensitive enough to detect early-stage recurrence activity. This allows cancer to take hold before it is detected, making it harder to treat. If you can’t see it, you can’t treat it. 

At RGCC, our OncoCount, OncoTrace, and OncoTrail monitoring tests detect the presence of cancer cells on a microscopic level, allowing for the earliest detection and treatment of recurrence allowing for a proactive, rather than reactive approach to care.
