Unconventional Cancer Treatments
Exploring Alternative Cancer Treatments: Promising Evidence for Vitamin C, Ivermectin, Soursop, and More
Cancer remains one of the most challenging diseases of our time, and while conventional treatments like chemotherapy and radiation are standard, many patients and researchers are exploring complementary and alternative therapies. Below, we dive into the most convincing evidence for several potential treatments—high-dose intravenous vitamin C, vitamin D, zinc, zinc ionophores (like hydroxychloroquine), amygdalin, ivermectin, baking soda, fenbendazole, soursop, and Larrea tridentata (creosote bush, chaparral, gobernadora, hediondilla)—with a special focus on colon cancer where relevant. These therapies range from well-studied to experimental, but all show intriguing potential. Always consult a healthcare professional before considering these treatments, as some carry risks or lack large-scale clinical validation.

1. High-Dose Intravenous Vitamin C (IVC): A Game-Changer in Cancer Care?
High-dose intravenous vitamin C (IVC) has emerged as a promising adjunctive therapy for cancer, including colon cancer. Unlike oral vitamin C, IVC delivers high concentrations directly into the bloodstream, acting as a pro-oxidant to generate reactive oxygen species (ROS) that selectively target cancer cells. This leads to metabolic stress and cell death in tumors while sparing healthy cells.
Most Convincing Evidence:
A phase 2 clinical trial published in November 2024 showed that IVC doubled overall survival in late-stage metastatic pancreatic cancer patients (from 8 to 16 months) when combined with chemotherapy. For colon cancer, preclinical studies demonstrate IVC's ability to inhibit proliferation in colon cancer cell lines, and a small clinical trial suggested reduced tumor hypoxia-inducible factors (HIF), which promote cancer growth. IVC also improves quality of life by reducing chemotherapy side effects like fatigue and nausea.
Why It Matters: IVC is non-toxic, well-tolerated, and shows synergy with standard treatments, making it a compelling option for further research.
2. Vitamin D: A Preventive Powerhouse
Vitamin D, known for its role in bone health, also shows promise in cancer prevention and treatment. It modulates immune responses, reduces oxidative stress, and may inhibit cancer cell growth by regulating gene expression.
Most Convincing Evidence:
A 2019 meta-analysis found that higher serum vitamin D levels were associated with a 33% lower risk of colorectal cancer mortality. Preclinical studies show vitamin D inhibits colon cancer cell proliferation by altering signaling pathways. The SU.VI.MAX trial also noted reduced total cancer incidence in men with vitamin D supplementation.
Why It Matters: While more effective for prevention than treatment, adequate vitamin D levels could improve outcomes for colon cancer patients.
3. Zinc: Boosting Immunity and Chemosensitivity
Zinc is critical for immune function and DNA repair, and it may enhance the effectiveness of cancer therapies by sensitizing cells to chemotherapy.
Most Convincing Evidence:
The SU.VI.MAX trial showed that a multivitamin supplement including zinc (20 mg) reduced total cancer incidence in men. For colon cancer, preclinical data suggests zinc enhances chemosensitivity, and its role in clearing HPV may indirectly lower cancer risk.
Why It Matters: Zinc is safe and affordable, making it a practical adjuvant, though direct evidence for colon cancer is limited.
4. Zinc Ionophores (e.g., Hydroxychloroquine): Amplifying Zinc's Effects
Zinc ionophores like hydroxychloroquine (HCQ) increase intracellular zinc levels, potentially disrupting cancer cell metabolism and inducing apoptosis.
Most Convincing Evidence:
In vitro studies show HCQ enhances zinc's ability to inhibit colon cancer cell growth by altering pH and inducing oxidative stress. A small trial in pancreatic cancer suggested improved tumor response with HCQ-chemotherapy combinations.
Why It Matters: While promising in lab settings, clinical data is sparse, and HCQ's risks (e.g., cardiotoxicity) warrant caution.
5. Ivermectin: From Parasites to Cancer?
Ivermectin, an antiparasitic drug, has gained attention for its potential to inhibit cancer cell growth by targeting Wnt/β-catenin signaling and inducing mitochondrial dysfunction.
Most Convincing Evidence:
A 2020 study in Frontiers in Pharmacology found ivermectin synergized with chemotherapy to enhance colon cancer cell death in vitro and reduced tumor growth in mouse models. Case reports suggest stabilized disease in some colon cancer patients.
Why It Matters: Ivermectin's low cost and established safety profile make it an exciting candidate, but human trials are needed.
6. Soursop (Graviola): A Tropical Hope for Colon Cancer
Soursop, rich in acetogenins, may inhibit mitochondrial function in cancer cells, inducing apoptosis. It's widely used in traditional medicine for cancer.
Most Convincing Evidence:
A 2017 study in Oxidative Medicine and Cellular Longevity found soursop leaf extract reduced colon cancer cell viability and tumor growth in mouse models. In vitro studies confirm its selective toxicity to colon cancer cells like HT-29 and HCT-116.
Why It Matters: Soursop shows strong preclinical promise for colon cancer, but human trials are needed, and high doses may cause neurotoxicity.
7. Fenbendazole: A Veterinary Drug with Human Potential?
Fenbendazole, an anthelmintic, may disrupt cancer cell microtubules and glucose metabolism, leading to apoptosis.
Most Convincing Evidence:
A 2021 study in Scientific Reports showed fenbendazole reduced tumor growth in mouse models of lymphoma and lung cancer. In vitro data suggests similar effects in colon cancer cells, and anecdotal reports (e.g., Joe Tippens protocol) claim remission in some patients.
Why It Matters: Anecdotal success stories are compelling, but clinical trials are needed to confirm efficacy and safety.
8. Larrea tridentata (Creosote Bush, Chaparral): A Traditional Remedy
Larrea tridentata, used in Native American and Mexican traditional medicine, contains nordihydroguaiaretic acid (NDGA), which may inhibit cancer cell growth by blocking signaling pathways.
Most Convincing Evidence:
A 2019 study in Journal of Ethnopharmacology found Larrea tridentata extracts reduced tumor growth in melanoma mouse models. In vitro studies suggest NDGA inhibits colon cancer cell proliferation, but human data is limited to anecdotal reports of symptom relief.
Why It Matters: Traditional use is promising, but liver toxicity risks and lack of clinical trials call for caution.
The Other Treatments: Promising but Less Studied
Amygdalin (Laetrile):
In vitro studies show amygdalin induces apoptosis in colon cancer cell lines, but clinical data is limited to 1970s–1980s case reports. Cyanide toxicity risks make it controversial.
Baking Soda (Sodium Bicarbonate):
A 2018 study found baking soda improved immune checkpoint inhibitor efficacy in mice by reducing tumor acidity. No human trials yet, and excessive use can cause metabolic imbalances.
Final Thoughts: Balancing Hope and Evidence
High-dose IV vitamin C leads the pack
due to its clinical trial data and safety profile. Soursop and ivermectin stand out for colon cancer in preclinical studies, while vitamin D and zinc offer preventive benefits. The lack of large-scale clinical trials for most of these treatments highlights the need for further research, but their potential shouldn't be dismissed outright, especially when used as adjuvants to standard care.
Key Takeaways:
- Strongest Evidence: High-dose IV vitamin C (clinical trials)
- Colon Cancer Promise: Soursop and ivermectin (preclinical)
- Preventive Benefits: Vitamin D and zinc
- Caution Required: Amygdalin, chaparral (toxicity risks)
⚠️ Safety First: If you're considering these therapies, work closely with a healthcare provider to weigh benefits against risks. Many of these treatments carry potential side effects and require medical monitoring.
