I was started on HRT aged 45 when suffering peri- menopausal symptoms. I had not even begun to consider HRT at that stage and had not looked into the pros and cons in any great detail before I found myself taking it on a locum doctor's advice. Of course my symptoms immediately disappeared and I felt wonderful. I raved to my friends about how marvellous it was and had no qualms about taking it, deciding that the benefits outweighed the risks. I began having problems about 5 years later. I have always had larger than average breast size (d cup when I began HRT) and I couldn't ignore the fact that they were getting larger. Not only that, they were becoming extremely painful, think pmt problems times 10! I then developed a large swollen area in one breast that was noticeable through my clothes and was extremely painful to touch. A mammogram showed that the problem was excess breast tissue, which was caused by the oestrogen in HRT. I was told I must come off it as soon as possible and I had horrendous symptoms, similar to all of the above mentioned ones in previous comments. It was so bad I was forced to go back on a different type of HRT, which I was eventually able to wean myself off over 6 months of gradually decreasing the daily dosage, becoming HRT free when I was 55. My point here is that although we are all aware there is an increased risk of breast cancer when taking HRT it is not really widely explained how the artificial hormones in HRT affects the production of breast tissue giving rise to the increased risk. The artificial hormone stimulates the production of tissue cells, but they do not behave in the same way as they do with natural oestrogen leading the breasts to enlarge and become very dense. This is not reversible, and I now am left with size G breasts and excess breast tissue in my armpits which always leads to a recall whenever I have a mammogram test. I really wish I had been better informed before starting on HRT, not least because I thought it meant you would miss the dreaded menopause... Not the case, because when coming off it you are still going to have symptoms as your body is having to adjust to the withdrawal of the hormones, even if they are artificial. It seems to me that in taking it, you are only delaying the time you will have to deal with it! This is only my own experience, and I completely understand that many of you are happy to take it as your symptoms are so impossible to live with. However if I had known then what I know now, I would never have taken it. I hope my experience helps some of you make an informed choice.
