Mostly false Certainty of evidence: moderate provisional C-CAN-03

The immune system does not fight cancer (no antibodies form against it), which shows the body accepts the tumour; therefore attacking it with chemotherapy is wrong.

Safety note: Do not refuse, stop or delay recommended cancer treatment (surgery, chemotherapy, radiotherapy, hormone or targeted therapy) in favour of a diet. In curable cancers, replacing standard treatment with alternative approaches is associated with a markedly higher risk of death (I-CHM-03, I-CHM-04), and even four-week delays are associated with higher mortality (I-CHM-07). Late effects are real and are managed by survivorship and cardio-oncology care; discuss them with the treating oncology team. Nutrition can be adapted alongside treatment with the oncology team. No individual medical advice is given here.
Conclusion: Immune evasion is a feature of cancer, not proof that the body wants the tumour.

Scientific assessment

Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.

Certainty of evidence: moderate – Further research may still affect the assessment.

1. What was claimed?

No immune response to cancer; the body tolerates it on purpose.

2. What is demonstrably correct?

Tumours evade immune control (e.g., via checkpoint pathways) and grow despite lymph-node passage; this is a real research topic.

3. What is wrong or exaggerated?

Releasing immune checkpoints lets T cells control metastatic melanoma in many patients (5-year survival 52% vs 26%; I-CHM-08). Immune evasion is a mechanism of cancer, not a sign that the tumour is beneficial.

4. What remains unclear?

Why some cancers respond to immunotherapy and others do not is still being studied; the cited trial concerns metastatic melanoma (I-CHM-08).

5. Which studies support it?

None for the conclusion. The kernel that tumours evade immune control (for example via checkpoint pathways) is real; checkpoint-inhibitor therapy (I-CHM-08) is built on it.

6. Which studies contradict it?

I-CHM-08.

7. What applies to Germany and Europe?

Not region-specific; checkpoint immunotherapy is used in European oncology for several cancers (not audited in detail).

8. What is known about Egypt?

Not region-specific; access to immunotherapy in Egypt was not reviewed.

9. What practical conclusion is appropriate?

Immunotherapy is an option for some cancers, chosen by oncologists.

Assessment details

Rationale for certainty of evidence

Immune evasion by tumours is real, but randomised immunotherapy trials show the immune system can control cancer; the conclusion against treatment does not follow.

general (biological/medical)
Last reviewed
25 October 2026 provisional

In plain language

Dr. Diaa argued that the body does not fight cancer and therefore wants it. In fact, cancers grow partly because they switch off immune defences. Modern drugs that remove these 'brakes' let the immune system attack the cancer, and half of patients with advanced melanoma were alive after five years.

    How was the study done?

    RCT.

General scientific assessment

Mostly false Immune evasion is a feature of cancer, not proof that the body wants the tumour.

This statement concerns biological or medical relationships. The scientific assessment above applies regardless of the country; country-specific food data do not change it.
