  • Can be considered for improving quality of life in those with breast cancer
  • Insufficient evidence for use for neutropeniaan abnormally low number of neutrophils in the blood, leading to increased susceptibility to infection/leukopeniaan abnormally low number of white cells in the blood, leading to increased susceptibility to infection

Expert commentary

According to CancerChoices advisor Gunver Kienle, MD, about half of all cancer patients in Germany use mistletoe. Breast cancer patients represent more than half of those using it. Anyone can purchase it in the pharmacy, but Dr. Kienle says having a doctor to prescribe and monitor it is much better. About half of doctors prescribe it and appreciate it. Some physicians are very experienced and knowledgeable, using very sophisticated methods of applying mistletoe, such as directly injected into the tumor, or by intravenous (IV) administration. According to Dr. Kienle, “High-dose IV or intralesional use is considered off-label and should be restricted to and monitored by experienced physicians.”3Abrams DI, Weil AT. Integrative Oncology, 2nd Edition. New York, NY: Oxford University Press. 2014, p. 576.
