Ozone Therapy for Breast Cancer: An Integrative Literature Review

Breast cancer is the most prevalent form of cancer in women. Despite significant advances in conventional treatment, additional safer complementary treatment options are needed. Recently, ozone therapy has been considered as a type of medical adjunctive treatment that could inhibit cancer cell survival and reduce chemoresistance. However, only a few studies have been conducted on its use in breast cancer, and the optimal dosage and time of administration are unknown. Currently, preclinical studies suggest that ozone alone or in combination with chemotherapy is an effective method for inhibiting breast cancer cell growth. However, rather than investigating the effects of ozone as an antitumor therapy, current clinical trials have generally assessed its effect as an adjunctive therapy for reducing chemotherapy-induced side effects, increasing oxygen tension, normalizing blood flow, restoring blood lymphocytes more rapidly, and reducing fatigue symptoms. In this article, the use of ozone as a medical adjunctive treatment for breast cancer and its role in integrative therapy are summarized and discussed.
