False Certainty of evidence: high provisional C-CHM-12

Cancer patients should not take chemotherapy, radiotherapy or biological therapy (or should stop them) and follow the Tayebat system instead; 'we are against the word medicine'.

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: Advice to avoid or stop chemotherapy and radiotherapy for a diet contradicts strong evidence and can be life-threatening.

Scientific assessment

False – The statement contradicts the robust evidence.

Certainty of evidence: high – Further research is very unlikely to change the assessment.

1. What was claimed?

Rejection of chemotherapy, radiotherapy and biologicals; presentation of patients who refused or stopped chemotherapy as successes.

2. What is demonstrably correct?

Elawady sometimes said patients decide themselves (P86iybRnOE4: those who want chemo may take it). End-of-life chemotherapy is often not beneficial (C-CHM-07). Side effects are real (C-CHM-01..06).

3. What is wrong or exaggerated?

In curable cancers, refusing chemotherapy, radiotherapy or surgery costs lives: alternative-only treatment HR 2.50 for death (breast cancer HR 5.68) (I-CHM-03); excess mortality with complementary medicine was mediated by refusal of conventional therapy (I-CHM-04); chemotherapy reduces breast-cancer mortality by about one-third (I-CHM-01); childhood ALL survival 90% (I-CHM-05). Even delays matter: in observational data, each 4-week delay (studied range about 4-16 weeks, in patients who were eventually treated) was associated with higher mortality (I-CHM-07); this concerns delay, not refusal. Individual reports of patients doing well without chemotherapy (e.g., after surgery) cannot show that the diet caused the outcome.

4. What remains unclear?

The outcomes of the specific patients mentioned in the videos are not verifiable.

5. Which studies support it?

None for the claim.

6. Which studies contradict it?

I-CHM-01, I-CHM-02, I-CHM-03, I-CHM-04, I-CHM-05, I-CHM-07.

7. What applies to Germany and Europe?

Standard of care in Europe.

8. What is known about Egypt?

Standard of care in Egypt follows the same evidence.

9. What practical conclusion is appropriate?

Never replace indicated cancer treatment with a diet; nutrition questions should be discussed with the oncology team.

Assessment details

Rationale for certainty of evidence

Randomised trials and large registries consistently show survival benefit of indicated treatment and excess mortality with refusal or delay.

Source quality

Multiple machine transcripts; consistent pattern with some contrary statements.

Regional transferability

High.

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

In plain language

In several videos Dr. Diaa spoke against chemotherapy, radiotherapy and biological drugs, and presented patients who stopped chemotherapy as successes. The scientific evidence is clear: for many cancers these treatments greatly increase the chance of survival. People who replace them with alternative methods die much more often, for breast cancer about five times as often in one large study. Individual stories cannot show that a diet cured a cancer.

Studies contradicting or limiting the claim (6)

  • Chemotherapy after breast-cancer surgery reduces deaths by about a third

    EBCTCG. Lancet 2012 · PMID 22152853 · DOI 10.1016/S0140-6736(11)61625-5
    Meta-analysisindependent cross-checkfull text checked★ key study

    In 123 trials with 100,000 women, modern regimens cut breast-cancer deaths by about one-third, and overall deaths fell too.

    Refusing chemo forgoes ~1/3 mortality reduction

    Does the study support the specific claim? No · Methodological quality: high · Certainty of evidence: see overall assessment of the claim

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Compare chemotherapy regimens and no chemotherapy.

    How was the study done?

    IPD meta-analysis of RCTs.

    How many people, animals or samples were studied?

    ~100,000 women.

    What was actually found?

    ~1/3 lower breast-cancer mortality.

    How large was the observed effect?

    RR 0.64-0.78 vs none.

    What do the results mean in everyday life?

    For many women, chemotherapy substantially raises the chance of survival.

    What are the study's limitations?

    Trials versus no chemotherapy are old (median start 1986); a small excess of non-breast-cancer deaths (e.g. heart, leukaemia) occurred; benefit is small when baseline risk is low.

    What does it say about Elawady's specific claim?

    Contradicts claims that chemotherapy is useless.

    Do the results apply to Germany and Europe?

    High.

    What can explicitly not be concluded from this study?

    Individual benefit without risk assessment.

  • Radiotherapy after breast-conserving surgery halves recurrence

    Meta-analysisindependent cross-checkfull text checked★ key study

    Recurrence within 10 years fell from 35% to 19%, and breast-cancer deaths within 15 years from 25% to 21%.

    Refusing RT increases recurrence

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Measure radiotherapy benefit.

    How was the study done?

    IPD meta-analysis.

    How many people, animals or samples were studied?

    10,801 women.

    What was actually found?

    What do the results mean in everyday life?

    Benefit side.

    Do the results apply to Germany and Europe?

    High.

    What can explicitly not be concluded from this study?

General scientific assessment

False Advice to avoid or stop chemotherapy and radiotherapy for a diet contradicts strong evidence and can be life-threatening.

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