We combine multiple evidence-based therapies to address the root of your condition. Whether you are fighting cancer, heart disease, chronic illness, or simply want to feel better — we have a treatment protocol for you.
Integrative medicine is a patient-centred approach that combines conventional medical knowledge with evidence-informed complementary therapies. At CancerSA in Centurion, integrative medicine is used to treat conditions including endometriosis, PCOS, autoimmune disease, chronic fatigue, heavy metal toxicity, and cardiovascular disease — using modalities such as chelation therapy, bio-oxidation therapy, ozone treatment, and IV nutrient therapy.
Each modality addresses different aspects of disease. Most patients receive a combination tailored to their specific condition.
This approach is part of integrative medicine, where treatments are selected based on individual patient needs and may be used alongside or in consideration of conventional medical care.

If you are a woman suffering from endometriosis, you know how debilitating it can be. And you know that surgery and hormone therapy alone do not always provide lasting relief. There is a reason for that.
Research is revealing a striking link between heavy metals and endometriosis. A large study found that women with the highest blood levels of mercury were 13 times more likely to have endometriosis (Pollack et al., Human Reproduction, 2013). Cadmium and lead tripled the risk. Arsenic increased it fivefold (Pollack et al., 2013).
These metals accumulate in your body over your lifetime from everyday sources — seafood, dental fillings, water, air pollution, cosmetics. They disrupt your hormones, inflame your tissues, and suppress the immune system that should be clearing misplaced endometrial tissue.
This may explain why surgery and hormone therapy alone do not always provide lasting relief. They treat the result, not the cause. If the toxic metals remain, the inflammation returns.
At Cancer SA, we treat endometriosis with a combination of therapies that address the root causes:
Removes the heavy metals (cadmium, lead, mercury) that research shows are 3–13x more prevalent in endometriosis patients
Published research shows significant pain reduction and drops in inflammatory markers (CRP, IL-1β) after just 4 sessions
Improves cellular oxygenation, boosts immune response, and addresses the oxidative stress documented in endometriosis
This combination addresses three pillars simultaneously: toxicity (chelation), inflammation (ozone), and immune function (bio-oxidation). Instead of suppressing symptoms, we remove what is driving them.
Polycystic Ovary Syndrome affects up to 10% of women and is driven by insulin resistance, hormonal imbalance, chronic inflammation, and — increasingly — environmental toxin exposure.
Multiple studies show that women with PCOS have significantly elevated levels of heavy metals including cadmium, lead, mercury, and arsenic. These metals act as endocrine disruptors, worsen insulin resistance, and increase inflammation. While the research on removing these metals as a PCOS treatment is still emerging, testing your heavy metal burden is a reasonable first step in understanding what may be contributing to your condition.
Our approach to PCOS is comprehensive and evidence-based:
Identify and address toxic metal burden
Guideline-supported supplements with strong evidence
First-line treatment per international PCOS guidelines
Berberine and nutritional strategies
Addressing the oxidative stress documented in PCOS
Studies show improved glucose tolerance and reduced testosterone
We are transparent: PCOS is a complex condition with no single magic treatment. Our role is to identify contributing factors — including environmental toxins most doctors do not test for — and address them alongside proven nutritional and lifestyle strategies.
If you have an autoimmune disease, your immune system is attacking your own body. The question your doctor may never have asked is: what triggered it?
A growing body of research shows that toxic heavy metals — mercury, lead, cadmium, and arsenic — can dysregulate the immune system in ways that promote autoimmunity. The mechanisms are well-characterised in laboratory research.
A case-control study of 100 patients found markedly elevated cadmium, lead, mercury, and antimony levels. The strongest evidence of any autoimmune disease.
A meta-analysis of 16 studies (1,650 patients) found significantly higher lead and arsenic levels in MS patients. Mercury exposure doubled the risk (OR=2.06; Napier et al., 2016).
Mercury accumulates in thyroid tissue in proportion to dental amalgam fillings. One study showed amalgam removal decreased thyroid autoantibodies.
Multiple studies show elevated cadmium, arsenic, and lead in Crohn's patients. Mercury exposure worsened UC reactivation in documented cases.
Mercury is selectively taken up by joint and connective tissue. Metal hypersensitivity is more common in RA patients. One RCT showed ozone + methotrexate outperformed methotrexate alone.
We are transparent with our patients: we cannot promise that removing heavy metals will cure your autoimmune disease. Autoimmunity is complex, involving genetics, gut health, hormones, stress, infections, and environmental triggers — of which toxic metals are just one piece.
What we can do is investigate whether your toxic metal burden is contributing to your immune dysfunction, and reduce it if so. For many autoimmune patients, this is a piece of the puzzle that conventional medicine never looks at.
Identify your specific toxic metal burden
Remove metals that may be triggering immune dysfunction
One RCT showed benefit alongside methotrexate for RA
Address intestinal permeability that metals may have caused
Reduce the oxidative stress driving inflammation
Anti-inflammatory diet, stress management, supplementation
The question worth asking: If heavy metals can dysregulate your immune system — and the evidence says they can — would it not make sense to check whether your body is carrying a toxic metal burden, and reduce it if it is? This is the investigation most conventional doctors never perform. We do.
First used in medicine in 1891. On the WHO List of Essential Medicines. Now at the forefront of mitochondrial and anti-ageing research.
Methylene blue is unique in medicine — it works directly inside your mitochondria, the energy factories inside every cell. When mitochondria are damaged or dysfunctional (from ageing, toxins, chronic illness, or cancer), your cells cannot produce enough energy.
You feel it as fatigue, brain fog, muscle weakness, and slow healing.
IV methylene blue acts as an alternative electron carrier — it bypasses the damaged parts of the mitochondrial energy chain, restoring ATP (energy) production. Think of it as a detour around a roadblock in your cell's power plant.
Research shows MB sensitises cancer cells to treatment, can overcome chemoresistance (including carboplatin resistance in ovarian cancer), and increases oxygenation in the tumour microenvironment — making cancer cells more vulnerable.
MB crosses the blood-brain barrier and enhances neuronal energy production. Studies show improved memory, reduced brain fog, neuroprotection, and potential benefits for Alzheimer's and Parkinson's patients.
A landmark study showed MB was more effective than other antioxidants at stimulating fibroblast growth, protecting telomeres, and reducing cellular senescence. It extended lifespan in mice by 6% and increased skin hydration and thickness in human skin models.
By restoring mitochondrial energy production, MB addresses the cellular fatigue underlying chronic fatigue syndrome. It also has antimicrobial, antiviral, and antifungal properties — effective against Lyme disease, chronic infections, and biofilms.
Important: IV methylene blue is screened for G6PD deficiency before administration (same screening as for IV Vitamin C). It is not suitable for patients taking SSRI antidepressants. Your temporary blue-tinged urine after treatment is completely normal — it simply means the methylene blue is being processed.
That is what the consultation is for. Bring your symptoms, your medical history, and your questions. Dr Pretorius will design a protocol specifically for you.
Treatment begins with an initial consultation where your medical history is reviewed in detail. A personalised plan is then developed based on your specific condition and goals.
Ongoing monitoring is carried out to assess response and adjust the approach as needed. Each patient's experience may differ depending on their overall health and treatment plan.
All treatments are provided within an integrative care framework and are tailored to the individual. They are not intended to replace necessary conventional medical care where required. Patients are encouraged to discuss all treatment options with their healthcare providers.
Individual results vary. The information on this website is for educational purposes and does not constitute medical advice.
