Re: Hormone replacement therapy
Martha Hickey and colleagues’ attempt to resurrect Hormone Replacement Therapy (HRT), by cobbling together selected data for 50 to 59 year olds from two disparate studies, still finds significant increases in breast cancer, strokes and venous thrombotic diseases.1
In reality women aged 50 to 59 cannot have a reduced overall mortality if they take HRT because cancers, vascular diseases and mental diseases are increased in women who take hormones at any age. Mortality was increased 3 fold in women under age 30 if they had ever taken oral contraceptives in the Royal College of General Practitioners study.2
Oral contraceptives were used previously by twice as many women taking oestrogen HRT than non-oestrogen takers in the Nurses’ Health Study. At baseline women who already had cancer were excluded, as were women who had coronary artery disease at each two yearly survey. By 1993 only 9% of the nurses enrolled were still taking HRT, 43% were taking vitamins and nine out of 10 did not believe that HRT was beneficial.3
Similarly HRT gave no overall benefit in the quality of life and doubled mortality from breast and lung cancers in the WHI randomised double blind trial.4,5 The Million Women Study found HRT doubled mortality from ovarian cancer.6
Simple physiological ways of avoiding vasomotor over-reactivity and osteoporosis at the normal physiological event of the menopause include repletion of measurable essential nutrient deficiencies and avoidance of masked food allergies, smoking, alcohol use and contributing medications. 7,8
The message should be that “HRT is dead and needs to be buried”.
