Health experts in the US have claimed that acupuncture treatment potentially increases breast cancer patients' sex drive and also reduces the side effects of hormone therapy.
According to researchers at Henry Ford Hospital, Detroit, acupuncture is as effective as drug therapy at reducing hot flashes in breast cancer patients and it also has the added benefit of potentially increasing a woman's sex drive and improving her sense of well-being.
The findings show that acupuncture, when compared to drug therapy, has a longer-lasting effect on the reduction of hot flashes and night sweats in the patients. Women also report that acupuncture improves their energy and clarity of thought.
"Acupuncture offers patients a safe, effective and durable treatment option for hot flashes, something that affects the majority of breast cancer survivors. Compared to drug therapy, acupuncture actually has benefits, as opposed to more side effects," says study lead author Eleanor Walker.
The study, published online in the Journal of Oncology, is the first randomly controlled trial to compare acupuncture and drug therapy in this way.
According to American National Cancer Institute, one in eight women will develop breast cancer in her lifetime. For these women, conventional medical treatment involves chemotherapy and five years of hormone therapy.

With such a long course of treatment, side effects of hormone therapy such as vasomotor symptoms ¿ hot flashes and night sweats ¿ can become a major cause of decreased quality of life, and even discontinuation of treatment.
Venlafaxine (Effexor) has been the drug therapy of choice to manage these common and debilitating side effects associated with breast cancer treatment. Venlafixine, however, comes with its own set of side-effects: dry mouth, decreased appetite, nausea and constipation.
Since acupuncture has been shown to effectively reduce hot flashes in menopausal women, Dr Walker and her team decided to test the use of acupuncture to combat vasomotor symptoms in breast cancer patients as an alternative to drug therapy.
To compare the two options, 50 patients were recruited from oncology clinics at Henry Ford. Patients were randomly assigned to receive either acupuncture or venlafaxine treatment for 12 weeks.
The study found that both groups initially experienced a 50 per cent decline in hot flashes and depressive symptoms, indicating that acupuncture is as effective as drug therapy.
Differences, however, between the two groups began to emerge two weeks post-treatment: The acupuncture group continued to experience minimal hot flashes, while the drug therapy group had a significant increase in hot flashes.
The acupuncture group did not experience an increase in the frequency of their hot flashes until three months post-treatment.
