Aim: In Canada, osteopathic medicine, a well-known branch of complementary/alternative medicine, has received minimal attention for pain management within oncology. Purpose: This review reports both the existing literature and patient experience surrounding the application of osteopathy as an effective treatment for pain in breast cancer patients. Results: Both the literature and this case study support, to some degree, the benefits of osteopathy as pain management for breast cancer patients. Conclusion: Due to contradictory reported findings, more studies would be required to make firm conclusions, especially within a Canadian context. However, a lack of standardization of osteopathic procedures and collaboration between osteopaths and traditional healthcare professionals are challenges in including osteopathy as a standard service offered to breast cancer patients.
