Hormone Replacement Therapy (HRT) is most often used for women undergoing menopause, either natural or surgical-induced.  It is used to improve the symptoms associated with menopause, such as hot flashes, mood swings, dry vagina, and urinary problems.

Women undergoing menopause experience these symptoms due to the lack of estrogen and/or progesterone.  Women who have had hysterectomies usually take estrogen while women who still have their uterus need to take a combination of estrogen and progesterone.

Research
HRT was widely used until 2002, when research indicated that it could be harmful and cause women to be at higher risk of certain diseases, such as heart attack, stroke, and breast cancer.  Most of the research, however, was done on women in their 60’s instead of in their 40’s and 50’s.  It is thought that the younger groups of women are at lower risk of getting these diseases than the older group.  On a brighter note, however, women’s risk levels for the other diseases go back down once they have been off of HRT for 4 to 5 years.

Fibroid tumors are non-cancerous cell overgrowths of the uterus.  They can form on the inside, outside, or wall of the uterus and can be as small as a pinpoint or as large as a well-developed pregnancy.  Fibroids occur during a woman’s childbearing years but once menopause starts, they often diminish in size.

What makes fibroids grow?
Both estrogen and progesterone must be present in order for fibroid tumors to grow in size.  Once women enter menopause, they stop making estrogen and progesterone, which is why fibroids become less of a problem at that time.

Birth control pills are thought to play a role in the growth of fibroid tumors, though not the actual cause of them.  It appears that the tumors grow when birth control pills are present in the system and slow down or stop if the pills are discontinued.
