Herbal remedies and mushroom-based treatments touted for cancer are not harmless by any means; they can be as dangerous to the body as conventional chemotherapy drugs. This warning appeared in Kommersant and has sparked caution among clinicians who study cancer care closely in North America and beyond.
In many cancer care settings, there are cytotoxic medications that originate from plant compounds. These agents are extremely potent poisons, capable of damaging cancer cells just as effectively as other chemical poisons used in chemotherapy, yet they are delivered through carefully controlled regimens. This understanding is echoed by Yana Mangasarova, who heads the department of chemotherapy for lymphatic tumors at a major national center focused on blood disorders. Her remarks emphasize that plant-derived compounds can be powerful cytotoxins, and their safety and dosing must be managed with the same rigor as synthetic drugs used in oncology. The implication for patients is clear: natural does not equal safe, and dose, timing, and medical supervision all matter profoundly in cancer treatment.
The expert also notes that combining certain herbs or mushrooms can create unpredictable and potentially life-threatening interactions. When medicines are used in tandem with other drugs, the interactions can alter how the body absorbs, metabolizes, or eliminates both substances. Conventional drugs have undergone extensive testing to map out these transformations, which helps doctors anticipate risks and tailor therapy to minimize harm. In contrast, the interactions within herbal blends are less predictable and often lack the same depth of study. The takeaway is simple: even seemingly gentle natural products can become dangerous when used without medical guidance, particularly for patients with cancer whose treatment plans rely on precise pharmacology and careful monitoring.
Herbal or fungal treatments can also erode the chances of recovery by delaying appropriate medical care. Mangasarova recounted a patient with a type of slow-growing lymphoma who chose to pursue a herbal approach instead of conventional therapy for an extended period. The patient began self-treating with a widely known mushroom, ingesting it daily for years while cancer progressed unchecked. Eventually the kidneys failed, leading to dialysis. The situation deteriorated to the point where the patient needed not only dialysis but also chemotherapy and, in some cases, organ transplantation later on. These drastic consequences illustrate a broader risk: delaying proven medical treatment in favor of alternative regimens can reduce the likelihood that standard therapies will be effective when they are finally pursued.
Years after the initial decision to avoid standard treatment, the cancer had accumulated additional mutations. This genetic evolution can blunt responsiveness to therapies that would have worked earlier, underscoring the central message that timely, evidence-based treatment often yields better outcomes. The oncologist highlighted that the best course of action is to pursue conventional treatment under the guidance of oncology professionals, with natural products approached only with informed caution and clear medical supervision. The history of this patient serves as a cautionary tale about how easily hopeful, self-directed choices can complicate medical trajectories, especially in hematologic cancers where responses can hinge on early, properly managed therapy.
In a broader sense, these discussions reinforce a practical principle for patients, families, and caregivers: talk openly with a physician about any herbs or supplements being considered, and share complete information about all medicines being used. This includes over-the-counter products, traditional remedies, and any mushrooms that might be part of daily meals or alternative regimens. Oncology teams can then assess potential risks, interactions, and the likelihood that a chosen natural product could interfere with standard treatment plans. Effective cancer care often depends on combining evidence-based medicine with patient education, ensuring that every step—from diagnosis to treatment choices and follow-up—rests on solid medical supervision and a clear understanding of potential side effects and interactions. This collaborative approach helps protect kidney function, liver health, and overall well-being while navigating the complexities of modern cancer therapy.
As in other regions with active cancer treatment programs, clinicians in North America and Europe stress that natural products must be evaluated with the same level of scrutiny as any prescribed drug. The aim is not to disparage herbal knowledge but to ensure patient safety and treatment efficacy. When used correctly, conventional therapies offer a track record of effectiveness that natural products cannot guarantee, especially given the serious consequences of delaying proven treatment. In this light, patients are encouraged to seek timely medical advice, understand the potential risks, and approach any alternative therapies with a clear plan that prioritizes evidence-based care and ongoing monitoring.
