化疗和肿瘤切除手术没有解决根本原因;身体会在别处重新启动它的“防御计划”,因此应避免这些治疗。
原始表述
حذّر الدكتور ضياء العوضي من العلاج الكيميائي والجراحة لإزالة الأورام، معتبراً أنها لا تعالج الأسباب الجذرية، وأن الجسم سيعيد تفعيل خطته الدفاعية في مكان آخر، ورأى أن الخلايا السرطانية تقاوم العلاج الكيماوي بسبب بيئتها الخلالية المتليفة.

Chemotherapy has to reach the whole interstitium and kills cells again, so the cancer becomes more aggressive and appears in places that cannot be controlled.

科学评估
错误 – 该说法与可靠证据相矛盾。
证据确定性: 高 – 进一步研究极不可能改变该评估。
1. 说法是什么?
Surgery/chemotherapy are futile because cancer is a defensive plan that will reappear elsewhere.
2. 哪些内容可证实是正确的?
Treatment does not remove all risk factors (e.g., continued smoking), and some cancers recur despite treatment; recurrence comes from residual or micrometastatic disease.
3. 哪些内容是错误或夸大的?
Recurrence is not an inevitable 'reactivation'. Radiotherapy after breast-conserving surgery reduced 10-year recurrence from 35.0% to 19.3% (I-CHM-02); chemotherapy reduces breast-cancer mortality by about one-third (I-CHM-01); delays of four weeks raise mortality (I-CHM-07); alternative-only care had HR 2.50 for death (I-CHM-03).
4. 哪些内容仍不明确?
There is a kernel of truth in the related transcript statement that chemotherapy can make cancer more aggressive: in mouse models and in residual human breast tumours after neoadjuvant chemotherapy, chemotherapy increased markers of cancer-cell dissemination (TMEM) and promoted metastasis in mice (I-INTB-04). This is a preclinical and surrogate-marker finding; it does not outweigh the reduction in breast-cancer mortality shown in randomised trials (I-CHM-01).
5. 哪些研究支持该说法?
Elawady's videos express the same idea (see alt_sources).
6. 哪些研究与该说法相矛盾?
I-CHM-01, I-CHM-02, I-CHM-03, I-CHM-07; I-CHM-120 (adjuvant gemcitabine vs observation: 5-year survival 20.7% vs 10.4%); I-CHM-102 (postmastectomy radiotherapy reduced overall recurrence and breast-cancer death); I-CHM-101. Mixed: I-INTB-04 (mouse dissemination markers, no human outcome data).
7. 对德国和欧洲而言情况如何?
Standard care is surgery plus risk-adapted adjuvant therapy.
8. 关于埃及的已知情况是什么?
Same.
9. 合理的实际结论是什么?
请勿拒绝或推迟有指征的手术或全身治疗。

总体证据说明了什么?
基于上述研究的编辑评估——其本身并非研究结果。
哪种观点有更好的证据支持?
Adjuvant chemotherapy and radiotherapy after surgery reduce distant recurrence and death; there is no evidence of a 'reactivation elsewhere' that cancels the benefit.
为什么有些研究权重更大
Randomised trials with distant recurrence and survival outcomes are decisive; a mouse dissemination signal cannot outweigh human survival data.
因果关系是否已确立? 是,已确立 Randomised comparisons.
仍存在的不确定性
Treatment-induced dissemination signals (I-INTB-04) deserve research but are not reflected in human outcomes.
合理的结论
False.
为什么研究结果看起来互相矛盾?
I-INTB-04 (dissemination markers after chemotherapy in mice) versus randomised trials (fewer distant recurrences): the biomarker signal is real in models but the net clinical effect in humans is fewer metastases and deaths.

Offer whole-breast radiotherapy after breast-conserving surgery with clear margins; offer postmastectomy radiotherapy for node-positive disease or involved margins; do not offer postmastectomy radiotherapy to people at low risk of local recurrence; where adjuvant chemotherapy is indicated, offer a regimen containing a taxane and an anthracycline and discuss benefits and risks. - WHO: Cancer - fact sheet (2026 (page fetched 2026-10-26)) · 原始文献
Many cancers can be cured if detected early and treated effectively; treatment usually includes surgery, radiotherapy and/or systemic therapy; some cancers such as testicular seminoma and childhood leukaemias and lymphomas have high cure rates with appropriate treatment even when spread; palliative care relieves symptoms in advanced cancer.

通俗解释
该档案网站说,Diaa 医生告诫人们不要接受化疗和手术,因为身体只会在别处再长出肿瘤。大型研究显示的结果恰恰相反:手术后,放疗能使复发的机会减半,化疗能使死亡的机会降低约三分之一。拒绝或推迟这些治疗的人死亡更多。
