CD Since the publication of the Women s Health Initiative study, there has been an increase in the use of non-hormonal therapies for the management of menopausal symptoms. Particularly for women with CHD and breast cancer risk factors, non-hormonal therapies may offer an alternative to assist with symptom management. A wide range of therapies, both prescription and herbal, have been studied with varying degrees of success. In choosing a particular therapy, it is important to match patient symptoms with a therapy that is not only effective but also safe. 

HRT is indicated primarily for the relief of moderate to severe vasomotor symptoms. It remains the most effective treatment for vasomotor symptoms and should be considered only in women experiencing those symptoms. Women with mild vasomotor symptoms may benefit from nonpharmacologic therapy alone however, many women will seek medical treatment for these symptoms. The benefits of HRT outweigh the risks in women who do not have CHD or CHD and breast cancer risk factors however, careful consideration should be given to alternative therapies for the relief of menopausal symptoms in women with these risks. Women should be involved in the decision and may choose to use HRT despite having some risk factors owing to the severity of their symptoms. Regardless of the situation, HRT should be prescribed at the lowest dose that relieves or reduces menopausal symptoms and should be recommended only for short-term use. Women should be reassessed every 6 to 12 months, and discontinuation of therapy should be considered.

Michigan contamination episode (Henderson et al. 1995 Hoque et al. 1998), but the results are only suggestive due to factors such as small number of cases, insufficient information on know n breast cancer risk factors, and confounding exposures to other organochlorine chemicals. The evidence for an association betw een breast cancer and PCBs is also not conclusive (Agency for Toxic Substances and Disease Registry 2000), and the hypothesis that environmental exposure to PCBs can cause breast cancer in humans is controversial (Safe and Zacharewski 1997 Wolff and Toniolo 1995). Overall, tlie evidence for an association between breast cancer and PBBs is inconclusive and needs further study.

The studies carried out in France are the only ones, they failed to demonstrate alcohol as a cancer risk factor. The data gathered in other regions indicate alcohol as an important cause of carcinogenesis. The risk of cancer development increases with the amount of alcohol consumed and becomes particularly high when accompanied by cigarette smoking (Anon., 1997 Doll, 1999).

All women should have a comprehensive family history taken that focuses on all the known ovarian cancer risk factors. Rectovaginal pelvic exam should be performed as part of ordinary medical care. 

As discussed above, associations between PCBs and breast cancer have been reported in only a few of the many case-control studies. Inconsistencies in the results could be related to methodological differences in the studies. For example, most of the breast tissue studies are limited by small numbers of subjects and/or inadequate control for known breast cancer risk factors, not all of the blood studies...
