Cancer remains a major global health concern, with an estimated 19.3 million new cases reported worldwide in 2020. Conventional treatments such as surgery, chemotherapy, and radiotherapy, although effective, are often associated with significant adverse effects that impact patients’ quality of life (QoL). Increasingly, patients are exploring complementary and alternative medicine (CAM), including homoeopathy, as supportive care. Homoeopathy, based on the principle of “like cures like,” aims to stimulate the body’s self-healing mechanisms through individualized treatment. Evidence suggests that adjunctive homoeopathic care may help alleviate treatment-related side effects and improve QoL in cancer patients. This review highlights the role of homoeopathy as a complementary approach in cancer management, emphasizing its potential benefits in enhancing patient well-being alongside conventional therapies.
