Treatment of Sweats and Hot Flashes in Patients with Cancer

    continued...

    Comfort measures may be used to treat sweats related to cancer. Since body temperature goes up before a hot flash, doing the following may control body temperature and help control symptoms:

    • Wear loose-fitting clothes made of cotton.
    • Use fans and open windows to keep air moving.
    • Practice relaxation training and slow, deep breathing.
    • Learn and practice self-hypnosis.

    Herbs and dietary supplements should be used with caution.

    Studies of vitamin E for the relief of hot flashes show that it is only slightly better than a placebo (pill that has no effect). Most studies of soy and black cohosh show they are no better than a placebo in reducing hot flashes. Soy contains estrogen-like substances; the effect of soy on the risk of breast cancer growth or recurrence is not clear. Studies of ground flaxseed to treat hot flashes have shown mixed results.

    Claims are made about several other plant-based and natural products as remedies for hot flashes. These include dong quai, milk thistle, red clover, licorice root extract, and chaste tree berry. Since little is known about how these products work or whether they affect the risk of breast cancer, women should be cautious about using them.

    Acupuncture may be used to treat hot flashes.

    Several studies have looked at the use of acupuncture to treat hot flashes. Results are not clear and more studies are needed. (See the Vasomotor symptoms section in the PDQ summary on Acupuncture for more information.)
