Common and Rare Side Effects
Women rarely have severe side effects from taking estrogens to replace estrogen. Discuss these possible effects with your doctor:
The prolonged use of estrogens has been reported to increase the risk of endometrial cancer (cancer of the lining of the uterus) in women after menopause. This risk seems to increase as the dose and the length of use increase. When estrogens are used in low doses for less than 1 year, there is less risk. The risk is also reduced if a progestin (another female hormone) is added to, or replaces part of, your estrogen dose. If the uterus has been removed by surgery (total hysterectomy), there is no risk of endometrial cancer, and no need to take an estrogen and progestin combination.
It is not yet known whether the use of estrogens increases the risk of breast cancer in women. Although some large studies show an increased risk, most studies and information gathered to date do not support this idea.
