Mostly false Certainty of evidence: moderate provisional C-CAN-01

Cancer is the body's own plan ('a self plan'): body cells are ordered to transform because this was necessary for the person's life; it is not caused by external agents.

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: Cancer is not a protective 'self plan'; it has well-established causes and can be attacked by the immune system.

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?

Cancer is a purposeful, protective transformation ordered by the body.

2. What is demonstrably correct?

Cancer cells derive from the body's own cells and use normal cellular programmes (growth, migration, hormone production), and tumours partly evade immune control - points Elawady describes.

3. What is wrong or exaggerated?

There is no evidence that tumours are 'ordered' for the person's benefit. About 40-44% of cancer cases/deaths are attributable to external modifiable factors, led by smoking (I-CAN-02, I-CAN-03); 2.2 million cancers per year are caused by infections (I-CAN-05). Nordic twin data show a heritable component of about 33%, with most of the remaining variation due to non-shared (individual) environment and chance; the authors stress that heritability is not a population-attributable fraction and does not reduce the role of lifestyle and environment (I-CAN-04). Neither finding supports a purely internal cause. When immune tolerance is lifted, the immune system can control metastatic cancer (I-CHM-08).

4. What remains unclear?

The teleological claim that the body 'orders' cancer for a purpose cannot be tested scientifically. The relative weight of chance, external and inherited factors differs between cancer types.

5. Which studies support it?

None for the claim that cancer is purposeful. The kernel that cancer arises from the body's own cells is textbook biology (not separately sourced).

6. Which studies contradict it?

I-CAN-01, I-CAN-02, I-CAN-03, I-CAN-04, I-CAN-05, I-CHM-08.

7. What applies to Germany and Europe?

Not region-specific; the heritability data come from Nordic twin cohorts (I-CAN-04) and the attributable fractions from US and global analyses (I-CAN-02, I-CAN-03).

8. What is known about Egypt?

Hepatitis B/C-related liver cancer is an example of an infection-driven cancer relevant to Egypt (I-CAN-05, global data).

9. What practical conclusion is appropriate?

Prevention (no tobacco, vaccination, healthy weight) and treatment are evidence-based; viewing cancer as protective may lead to dangerous delays.

Assessment details

Rationale for certainty of evidence

Not testable in its teleological form; contradicted by strong evidence on carcinogens, infections, heredity and immune control. Partial truth: cancer arises from the body's own cells and exploits normal programmes.

Regional scope of the claim
general (biological/medical)
Last reviewed
25 October 2026 provisional

In plain language

Dr. Diaa described cancer as a plan of the body that is necessary for the person. Science shows that cancer starts in our own cells, but it is mostly caused by damage to the genes from smoking, infections, alcohol, radiation, inherited factors and chance. The immune system can attack cancer when helped by modern drugs. There is no evidence that a tumour protects the body.
