Reiki, a stress reduction and relaxation technique, has become a subject of curiosity for cancer patients everywhere. Studies and anecdotal evidence has shown that, in addition to promoting relaxation among patients, Reiki can also be used to encourage healing and provide other benefits. In fact, some studies have even explored the effect of Reiki on patients who are undergoing cancer treatment concurrently. These studies have found that, although Reiki is not a substitute for other cancer treatments, it may enhance these treatments and offer a number of benefits to patients as they deal with the symptoms and stresses of cancer.
