Hormone replacement therapy ups cancer risk
If you are a woman thinking of undergoing hormone replacement therapy (HRT), think again. I have found that studies conducted throughout the world suggest that long term HRT significantly increases the risk of cancer.
Long-term use of estrogen-only HRT increases the risk of breast cancer, a major US study suggests. Those who had been taking estrogen for fewer than 10 years did not appear to have a higher risk than those who had never taken hormones. But those who had been taking the hormone for more than 20 years had a significantly increased risk.
So whether you start or continue taking HRT needs to be an informed choice made with the help of your doctor. I feel you should also review the progress every year and decide accordingly.
