Doctors are expressing concern that some people diagnosed with cancer are choosing ivermectin—a drug typically used as an anti-parasitic treatment in animals—to try to treat their cancer, rather than pursuing standard chemotherapy. The reports describe a renewed public interest in ivermectin and note that its renewed attention is not linked to COVID-19 this time. Clinicians say the decision is worrying because ivermectin is not an established cancer therapy and can carry risks, including side effects and potential interactions with cancer treatments. Health professionals emphasize that cancer care decisions should be based on evidence from clinical trials and guidelines, and they warn that delaying or foregoing chemotherapy could allow cancers to progress. While the articles focus on doctors’ concerns and the trend toward ivermectin, they do not provide detailed information on how widespread the behavior is or specific patient outcomes. Overall, the coverage highlights the tension between patient-driven efforts to find alternative therapies and the medical community’s view that chemotherapy and other standard treatments remain the evidence-based options for most cancers.
