A review of complementary and alternative medicine used in cancer care: challenges and prospects

Cancer is a leading cause of death globally, and most patients with cancers frequently seek for complementary and alternative medicine (CAM) to ameliorate their condition. Some of the available CAM care include: acupuncture, aromatherapy, Ayurvedic medicinal drug, cannabis, chelation remedy, homeopathy, hypnotherapy, massage therapy, naturopathic medication, and conventional Chinese remedy amongst others. Despite the growing use of CAM, the evidence-base for its efficacy and safety is limited. Major challenges confronting the efficient deployment of CAM is lack of standardization and regulation; as well as the demand for more extensive studies to validate their safety and efficacy. Integrative oncology which is the combination of CAM and conventional cancer care is likewise complicated through the potential adverse interactions between CAM options and most cancers drugs. The article serves as a guide for healthcare providers and patients to determine how CAM can be safely integrated into the cancer care paradigm. Taking into account safety concerns, however, more studies need to be conducted to properly evaluate its efficacy. Ultimately, CAM can help cancer patients in achieving greater health and well-being.
