What was claimed

A new study showed over 50% of skin cancer was healed with Vitamin C and DMSO (promoting Ivermectin + DMSO regimen).

Our verdict

Inaccurate

The cited studies used topical ascorbic acid in DMSO or imiquimod as a comparator. Ivermectin is not part of the trial described in the sources. A study did report 56% complete histologic resolution in SCC in situ lesions and 86.7% resolution in a basal cell carcinoma trial, but the wording overstates this as a general skin-cancer cure and omits that the evidence is limited to small studies.

Detailed Analysis

The claim is materially wrong. The cited study was about topical ascorbic acid (vitamin C) in DMSO for biopsy-confirmed basal cell carcinoma and SCC in situ, not a broad result that “over 50% of skin cancer was healed,” and it did not involve ivermectin.[14] [8] [9] Authoritative cancer sources also state there is no evidence that DMSO treats cancer in humans.[9] [13]

Vitamin C and DMSO healed skin cancer.

Can’t verify78%
Small studies reported lesion clearance or reduction in selected non-melanoma skin cancers, but major cancer sources say there is no evidence DMSO treats cancer in humans. That makes a broad healing claim unsupported.[9] [13]

What other AI think

The claim contains a mix of accurate and significantly misleading elements. While vitamin C and DMSO studies do show promising results for certain skin cancers, the claim misrepresents the evidence and makes an unsubstantiated claim about ivermectin. The "over 50%" figure is accurate for one specific study, but the statement about "promoting Ivermectin + DMSO regimen" is false—no clinical evidence supports ivermectin for skin cancer treatment.

Claims checked

The regimen promotes Ivermectin + DMSO for skin cancer treatment

Incorrect95%
No clinical evidence supports ivermectin for skin cancer treatment in humans. Ivermectin has shown effects only in laboratory studies, not in human trials. The claim that this regimen 'promotes' ivermectin is false—the actual studies tested vitamin C in DMSO, not ivermectin. Ivermectin is not approved for cancer treatment and lacks high-quality clinical evidence.

This claim may mislead readers without added context.

A new study showed over 50% of skin cancer was healed with Vitamin C and DMSO

Misleading92%
A 2025 study did find 56% complete histologic resolution of squamous cell carcinoma in situ with vitamin C and DMSO. However, this applies only to one specific type of skin cancer (SCCIS), not 'skin cancer' broadly. Additionally, a 2022 study on basal cell carcinoma found 86.7% resolution, not 50%. The claim oversimplifies and misrepresents which study achieved which results.

This claim may mislead readers without added context.

Vitamin C and DMSO combination is effective for skin cancer

Verified88%
Clinical studies do show promising results. A 2022 randomized trial found 86.7% complete resolution for basal cell carcinoma, and a 2025 study found 56% complete resolution for squamous cell carcinoma in situ. However, these are small studies and results are specific to certain skin cancer types.
The statement mixes two different and not-equivalent claims. Early clinical reports and preprints do report promising response rates for topical ascorbic acid (vitamin C) in DMSO against specific non‑melanoma skin cancers, but those results are limited, tumor-type specific, and not definitive. There is no robust clinical evidence that an Ivermectin + DMSO regimen cures skin cancer or that the vitamin C+DMSO studies endorse ivermectin use.

Claims checked

The study promoted an Ivermectin + DMSO regimen for treating skin cancer.

Incorrect95%
The vitamin C + DMSO studies do not provide evidence endorsing ivermectin with DMSO as a cancer cure, and there are no high‑quality clinical trials showing ivermectin+DMSO cures human skin cancer.

This claim may mislead readers without added context.

A new study showed over 50% of skin cancer was healed with Vitamin C and DMSO.

Misleading86%
Recent small trials and preprints report high complete-response rates (for example, reports of ~56% elimination or higher in specific basal cell or squamous cell in situ cohorts), but these are limited, tumor‑type specific, often preprint or small open‑label trials, and not general proof that 'over 50% of skin cancer' is cured across all skin cancers.
