 How should women who may have been 
            prescribed DES during pregnancy be counseled?
 No specific 
              health behavior changes are recommended on the basis of DES exposure 
              alone. The contribution of DES exposure during pregnancy to breast 
              cancer risk should be considered when deciding about hormone replacement 
              therapy or the use of Tamoxifen to prevent breast cancer. Women 
              prescribed DES while pregnant should be encouraged to obtain regular 
              breast examinations and mammograms as currently recommended by the 
              National Cancer Institute, which can be found at www.cancer.gov, 
              or by the American Cancer Society, www.cancer.org. Women prescribed DES while pregnant should be 
              encouraged to inform children who may have been exposed in utero. 
              This is of particular importance since research on DES Daughters 
              and Sons is ongoing and may reveal currently unknown health effects. 
              Many women prescribed DES while pregnant are elderly. If their children 
              are not informed of their potential risk, opportunities for future 
              intervention may be lost.  For more information on health risks and ongoing studies for DES 
              Daughters, DES Sons and the Third Generation, refer to the following
