Findings also show there were additional benefits to acupuncture treatment for breast cancer patients, such as an increased sense of well being, more energy, and in some cases, a higher sex drive, that were not experienced in those patients who underwent drug treatment for their hot flashes.

"Our study shows that physicians and patients have an additional therapy for something that affects the majority of breast cancer survivors and actually has benefits, as opposed to more side effects. The effect is more durable than a drug commonly used to treat these vasomotor symptoms and, ultimately, is more cost-effective for insurance companies," Eleanor Walker, M.D., lead author of the study and a radiation oncologist at the Henry Ford Hospital Department of Radiation Oncology in Detroit, said.

The reduction in hot flashes lasted longer for those breast cancer patients after completing their acupuncture treatment, compared to patients after stopping their drug therapy plan.

Eighty percent of women treated for breast cancer suffer from hot flashes after being treated with chemotherapy and/or anti-estrogen hormones, such as Tamoxifen and Arimidex. Although hormone replacement therapy is typically used to relieve these symptoms, breast cancer patients cannot use this therapy because it may increase the risk of the cancer coming back.

As a treatment alternative, patients are generally treated with steroids and/or antidepressant drugs. These drugs, however, have additional side effects, such as weight gain, nausea, constipation and fatigue. The antidepressant, venlafaxine (Effexor), a selective serotonin reuptake inhibitor, is one of the most common drugs used to treat these hot flashes. However, many women decide against this treatment choice because of potential side effects, including decreased libido, insomnia, dizziness and nausea, or because they simply do not want to take any more medications.
