AUTHORS ' CONCLUSIONS : Women with intolerable menopausal symptoms may wish to weigh the benefits of symptom relief against the small absolute risk of harm arising from short-term use of low-dose HT , provided they do not have specific contraindications .
HT may be unsuitable for some women , including those at increased risk of cardiovascular disease , increased risk of thromboembolic disease ( such as those with obesity or a history of venous thrombosis ) or increased risk of some types of cancer ( such as breast cancer , in women with a uterus ) .
The risk of endometrial cancer among women with a uterus taking oestrogen-only HT is well documented .
HT is not indicated for primary or secondary prevention of cardiovascular disease or dementia , nor for prevention of deterioration of cognitive function in postmenopausal women .
Although HT is considered effective for the prevention of postmenopausal osteoporosis , it is generally recommended as an option only for women at significant risk for whom non-oestrogen therapies are unsuitable .

Effects of estrogen plus progestin on risk of fracture and bone mineral density: the Women's Health Initiative randomized trial.
CONTEXT In the Women 's Health Initiative trial of estrogen-plus-progestin therapy , women assigned to active treatment had fewer fractures . OBJECTIVE To test the hypothesis that the relative risk reduction of estrogen plus progestin on fractures differs according to risk factors for fractures . DESIGN , SETTING , AND PARTICIPANTS R and omized controlled trial ( September 1993-July 2002 ) in which 16 608 postmenopausal women aged 50 to 79 years with an intact uterus at baseline were recruited at 40 US clinical centers and followed up for an average of 5.6 years . INTERVENTION Women were r and omly assigned to receive conjugated equine estrogen , 0.625 mg/d , plus medroxyprogesterone acetate , 2.5 mg/d , in 1 tablet ( n = 8506 ) or placebo ( n = 8102 ) . MAIN OUTCOME MEASURES All confirmed osteoporotic fracture events that occurred from enrollment to discontinuation of the trial ( July 7 , 2002 ) ; bone mineral density ( BMD ) , measured in a subset of women ( n = 1024 ) at baseline and years 1 and 3 ; and a global index , developed to summarize the balance of risks and benefits to test whether the risk-benefit profile differed across tertiles of fracture risk . RESULTS Seven hundred thirty-three women ( 8.6 % ) in the estrogen-plus-progestin group and 896 women ( 11.1 % ) in the placebo group experienced a fracture ( hazard ratio [ HR ] , 0.76 ; 95 % confidence interval [ CI ] , 0.69 - 0.83 ) . The effect did not differ in women stratified by age , body mass index , smoking status , history of falls , personal and family history of fracture , total calcium intake , past use of hormone therapy , BMD , or summary fracture risk score . Total hip BMD increased 3.7 % after 3 years of treatment with estrogen plus progestin compared with 0.14 % in the placebo group ( P<.001 ) . The HR for the global index was similar across tertiles of the fracture risk scale ( lowest fracture risk tertile , HR , 1.20 ; 95 % CI , 0.93 - 1.58 ; middle tertile , HR , 1.23 ; 95 % CI , 1.04 - 1.46 ; highest tertile , HR , 1.03 ; 95 % CI , 0.88 - 1.24 ) ( P for interaction = .54 ) . CONCLUSIONS This study demonstrates that estrogen plus progestin increases BMD and reduces the risk of fracture in healthy postmenopausal women . The decreased risk of fracture attributed to estrogen plus progestin appeared to be present in all subgroups of women examined . When considering the effects of hormone therapy on other important disease outcomes in a global model , there was no net benefit , even in women considered to be at high risk of fracture
