Many people who have been diagnosed with cancer use complementary health approaches. According to the 2007 National Health Interview Survey (NHIS), which included a comprehensive survey on the use of complementary health approaches by Americans, 65 percent of respondents who had ever been diagnosed with cancer had used complementary approaches. Those who had been diagnosed with cancer were more likely than others to have used complementary approaches for general wellness, immune enhancement, and pain management.
A substantial amount of evidence suggests that some complementary health approaches, such as acupuncture, massage therapy, mindfulness-based stress reduction, and yoga may help to manage some cancer symptoms and side effects of treatment. For other complementary approaches (e.g., natural products), the evidence is more limited. This issue of the digest provides information on the evidence base on complementary and integrative health approaches for cancer-related symptoms and treatment side effects.
Modality and Summary of Current Evidence
Acupuncture
a Mind and Body Approach
There is evidence that acupuncture can help to manage chemotherapeutic-induced nausea and vomiting in cancer patients. There isn’t enough evidence to determine whether acupuncture relieves cancer pain or other symptoms such as treatment-related hot flashes or xerostomia.
Massage
a Mind and Body Approach
Studies suggest that massage therapy may help to relieve cancer-related symptoms such as pain, nausea, anxiety, and depression. However, investigators haven’t reached any conclusions about the effects of massage therapy because rigorous research in this field is lacking.
Mindfulness-Based Stress Reduction
a Mind and Body Approach
There is evidence that mindfulness-based stress reduction can help patients with cancer relieve anxiety, stress, fatigue, and general mood and sleep disturbances, thus improving their quality of life. Most participants in mindfulness studies have been patients with early-stage cancer, primarily breast cancer, so the evidence favoring mindfulness training is strongest for this population.

Yoga
a Mind and Body Approach
Preliminary evidence suggests that yoga may help to decrease anxiety, depression, and stress in people with cancer. It also may help to lessen fatigue in breast cancer patients and survivors. However, only a small number of yoga studies in cancer patients have been completed, and some of the research has not been high quality.
Ginger
a Natural Product
Recent studies suggest that the herb ginger may help to control nausea related to cancer chemotherapy when used as adjunctive therapy to conventional anti-emetics.
