Hyperthermia — Heat That Heals
Controlled infrared heat selectively targets cancer cells, enhances chemotherapy uptake, and activates your immune system.
At a Glance
- Controlled heat (39–42°C) using an infrared blanket during IPTLD and IV Vitamin C
- Cancer cells are more sensitive to heat than healthy cells — heat damages them selectively
- Increases drug uptake, boosts immune response, and impairs cancer cell DNA repair
- Comfortable and painless — you lie under a warm blanket during treatment
- Used on Day 1, 3, and 4 of the weekly cancer protocol
This approach is part of integrative oncology, where treatments are selected based on individual patient needs and may be used alongside or in consideration of conventional medical care.
Hyperthermia therapy is an integrative cancer treatment that uses controlled infrared heat (39–42°C) to sensitise cancer cells, making them more vulnerable to chemotherapy and other treatments. Cancer cells are less able to tolerate heat than healthy cells, and clinical research has shown that combining hyperthermia with other therapies may improve treatment outcomes.

What Is Hyperthermia?
Hyperthermia is a medical treatment that uses controlled heat to raise body tissue temperature to between 39°C and 42°C (102-108°F). At Cancer SA, this is achieved using infrared technology — a safe, non-invasive method of delivering deep, penetrating warmth to the body.
The concept of using heat to fight disease is not new. Physicians have observed for centuries that patients who developed high fevers sometimes experienced remission of their cancers. Modern hyperthermia takes this observation and applies it in a controlled, reproducible medical setting, used alongside or in consideration of conventional oncology care. At Cancer SA in Centurion, Pretoria, hyperthermia is a core part of our integrative cancer protocol, available to patients from across Gauteng and South Africa.
Unlike a natural fever, therapeutic hyperthermia is precisely controlled and monitored throughout the session. The temperature is maintained within a specific range that is damaging to cancer cells but safe for healthy tissue — exploiting a fundamental vulnerability in the biology of cancer.
How Hyperthermia Fights Cancer
Cancer cells are more vulnerable to heat than normal, healthy cells. This is due to several biological differences that hyperthermia exploits:
Heat Sensitivity
Cancer cells have disorganised blood vessel networks and poor heat regulation. When temperatures rise, they cannot cool themselves effectively — making them more susceptible to heat damage than healthy cells.
Protein Damage
Heat denatures (unfolds) proteins inside cancer cells, disrupting the enzymes and structural components they need to survive, divide, and repair themselves. This damage accumulates and leads to cancer cell death.
Apoptosis Induction
Sustained heat triggers programmed cell death (apoptosis) in cancer cells. Unlike necrosis, apoptosis is a controlled process that allows the immune system to clean up dead cancer cells without causing inflammation.
Hyperthermia + IPTLD — A Powerful Combination
At Cancer SA, hyperthermia is not used in isolation. Its greatest power lies in how it enhances other treatments in the protocol — particularly IPTLD low-dose chemotherapy.
When the body is heated to therapeutic temperatures, several things happen that directly amplify the effect of chemotherapy:
- Cell Membranes Open: Heat increases the permeability of cell membranes, allowing more chemotherapy to enter cancer cells. Combined with insulin potentiation, this creates a dual mechanism for driving medicine directly into tumour cells.
- Blood Flow Increases: Heat dilates blood vessels and increases blood flow to tissues, improving the delivery of chemotherapy drugs to tumour sites that may otherwise have poor blood supply.
- DNA Repair is Inhibited: Heat impairs the ability of cancer cells to repair DNA damage caused by chemotherapy. This means the low-dose chemotherapy achieves a greater effect than it would at normal body temperature.
Every patient's protocol is different — Dr Pretorius tailors the treatment to your specific cancer, response, and needs. In a typical week, hyperthermia is administered on Days 1, 3, and 4. On Days 1 and 4, it is combined with IPTLD chemotherapy. On Day 3, it accompanies mega-dose IV Vitamin C (± IV Methylene Blue) under insulin potentiation. Day 2 is dedicated to oxidation therapy (IV H₂O₂ + DMSO) and EDTA chelation with ozone sauna. During Phase 1 (weeks 1–6/8), treatment runs 4 days per week. In Phase 2 (weeks 7/9–16/20), the second IPTLD session (Day 4) is dropped based on patient response, reducing to 3 days per week. The full protocol runs for 16–30 weeks (average 16–20).
Activating the Immune System
One of the most significant benefits of hyperthermia is its ability to activate the immune system. The body interprets therapeutic heat as a fever — and responds accordingly.
Fever-range temperatures trigger a powerful cascade of immune responses:
- Natural Killer Cell Activation: NK cells are the immune system's first line of defence against cancer. Hyperthermia significantly increases their activity and ability to recognise and target cancer cells.
- Dendritic Cell Maturation: Heat promotes the maturation of dendritic cells, which are responsible for presenting cancer antigens to the immune system — essentially teaching the immune system what to attack.
- Heat Shock Proteins: Cancer cells under heat stress release heat shock proteins on their surface, effectively "flagging" themselves for immune detection. This makes cancer cells more visible to the immune system.
- Cytokine Release: Hyperthermia stimulates the production of immune-signalling molecules that coordinate a broader, more effective immune response against cancer throughout the body.
This immune activation is a critical component of our treatment philosophy — empowering your own body to fight the cancer alongside the direct anti-cancer treatments in the protocol.
What to Expect During Treatment
Hyperthermia at Cancer SA is administered using an infrared blanket system — a comfortable, non-invasive approach that requires no injections, incisions, or anaesthesia.
- You will lie on a treatment bed and be wrapped in the infrared blanket.
- The infrared heat penetrates deeply into the body, gradually raising your core temperature to the therapeutic range of 39-42°C.
- Sessions typically last 45 to 60 minutes.
- Most patients describe the experience as warm and comfortable — similar to lying under a heated blanket. You may perspire, which is normal.
- Your temperature and vital signs are monitored throughout the session.
- When combined with IPTLD or IV Vitamin C, the hyperthermia session runs concurrently with the IV infusion.
Hyperthermia is an out-patient treatment. After your session, you can resume your normal activities. Some patients feel mild fatigue or increased thirst after treatment — staying well-hydrated before and after your session is recommended.
