Healthcare must engage in a wider discussion about preventive medicine
by Alan Cassels
• “Preventive medicine displays all three elements of arrogance…Aggressively assertive…Presumptuous…Overbearing.”
Dr. David Sackett wrote those words over a decade ago in a neat little column in the Canadian Medical Association Journal. He was, in this case, talking about hormone replacement therapy, after the publication of one of the world’s largest studies in preventive healthcare. The results of the Women’s Health Initiative showed that giving estrogen and progestin to healthy women going through menopause, on the assumption that this was vital preventive medicine, did not protect them from cardiovascular disease. In fact, it increased rates of some forms of cancer, heart attacks, blood clots and strokes. In trying to preserve and protect health, the recommended therapies were harming women. On a massive scale, I should add.
