Background. Patients with cancer pursue all possible opportunities of effective remedies. In Saudi Arabia, most patients have tried complementary medicine during their cancer treatment plan; however, some complementary medicines might pose a danger to health. In Arab countries, studies regarding the use of complementary medicines and the intentions behind using complementary medicines among cancer patients are inadequate and all but nonexistent. The aim of this review was to focus on demographic, prevalence, and reasons for complementary and alternative medicine use among patients with cancer. Methods. A rigorous literature search was conducted for articles published in the English language, using the search terms “complementary and alternative medicine,” “oncology,” “malignancy” AND “cancer patients” in five scientific databases, namely, Medical Literature On-Line (MEDLINE), PubMed, Web of Science, Psychology Information (PsycINFO), and Google Scholar, from 2010 to 2020. Results. Of the 13,160 studies returned from the search, only 12 were eligible and included in this review. The combined prevalence for using complementary and alternative medicines across all studies totaled 25%–80% of cancer patients for the treatment of their cancers. Natural products, including vitamins and minerals, herbal products, and relaxation, were the most common type of complementary and alternative medicines used. The reason for using complementary and alternative medicines was reported to be their helpfulness in recovering, healing, and improving health. Most of the studies mentioned that participants obtained their complementary and alternative medicines from multiple sources, including the media, family and friends, and physicians. Conclusion. The use of complementary and alternative medicines in cancer patients can be inferred as an attempt to investigate all possibilities, a manifestation of a coping style, or an illustration of unmet desires in the cancer management continuum. Anyhow, there should be adequate communication between healthcare providers and patients, which is crucial for establishing a trusting healthcare provider-patient relationship. Relevance to clinical practice. It is crucial that healthcare providers explore the use of complementary and alternative medicines with their cancer patients, as well as educating them about the possible usefulness of therapies based on the available evidence.
