Hormone replacement therapy, or HRT, can be a highly effective way to relieve disruptive menopause symptoms, including hot flashes, night sweats, sleep disturbances, and mood changes. Dr. Truong Nguyen, an assistant professor in the Department of Obstetrics and Gynecology and director of Minimally Invasive Gynecologic Surgery (MIGS) at The University of Texas Medical Branch (UTMB), said it is not a one-size-fits-all solution.
As many board-certified OB-GYNs emphasize, the decision to use HRT depends on a careful balance of benefits and risks, including a patient’s medical history, age, and symptom severity. For healthy menopausal patients without contraindications, systemic estrogen — with or without progesterone — can safely restore quality of life. Low-dose vaginal estrogen may be used specifically for localized symptoms such as vaginal dryness or recurrent urinary tract infections.
The risk-benefit calculation is especially important for women with a history of cancer. Even for women with a history of endometrial cancer, hormone therapy is not automatically off the table. Instead, it requires an individualized, collaborative approach among the patient, gynecologist, and oncologist to determine what is safe and effective.
Nguyen offers insight and guidance for women considering HRT as they move through perimenopause and menopause.
What exactly is hormone replacement therapy, and how do I know if it might be right for me?
“If a woman is having symptoms that are interfering with her quality of life, such as night sweats, hot flashes, and sleep disturbance, and has no history of breast cancer, blood clots, stroke, or other cardiovascular conditions, then I recommend starting a low dose of estrogen or progesterone,” Nguyen said. “The purpose of systemic HRT is to replace the hormones that are diminishing during perimenopause and menopause and to treat these systemic symptoms.”
Nguyen said some women benefit from estrogen alone, while others may do better with a combination of estrogen and progesterone to protect both bone and uterine health.
“The goal is to help each patient feel more like herself again, taking all the risks and benefits of her medical history into consideration,” he said.
If I’ve had endometrial cancer, does that mean hormone therapy is off the table?
“There is a concern that HRT might influence cancer cells, so we have to individualize the treatment,” Nguyen said. “For example, if a woman is using vaginal estrogen to address vaginal dryness or recurrent bladder infections, that is not considered HRT. These treatments do not contain enough hormones to address broader menopausal symptoms — only localized vaginal symptoms.”
For patients with a history of endometrial cancer, Nguyen said outcomes are not affected by the twice-weekly use of vaginal estrogen.
“Young women with early-stage endometrial cancer who have completed treatment and are stable may be candidates for systemic hormone replacement in the form of a pill, patch, or cream,” he said.
What’s the difference between full hormone therapy and vaginal estrogen — and why would I use one over the other?
Both vaginal estrogen and full, or systemic, hormone therapy treats menopause symptoms but in different ways.
Vaginal estrogen is a low-dose, localized treatment used to relieve symptoms such as dryness, urinary discomfort, burning, itching, or painful intercourse caused by thinning vaginal tissue, a condition known as genitourinary syndrome. Because it remains localized and does not significantly enter the bloodstream, it is considered safe for many patients, including those who may not be candidates for systemic HRT.
“Full HRT involves estrogen and progesterone that circulate throughout the body,” Nguyen said. “This can include pills, patches, gels, or sprays and is typically prescribed when symptoms are more widespread or severe.”
Nguyen emphasized the importance of listening to patients and tailoring care accordingly.
“We listen to the patient to treat the specific problem she is having,” he said. “If it’s painful intercourse, a lubricant may be all that’s needed. If she is younger and at low risk for cancer, vaginal estrogen two or three times a week is very safe and effective.”
How do doctors decide if estrogen is safe for someone with a history of endometrial cancer?
Determining whether estrogen is safe after endometrial cancer treatment depends on several factors, including cancer type and stage, current health status, and symptom severity.
“During active cancer treatment, managing menopausal symptoms usually involves nonhormonal methods,” Nguyen said. “Once treatments are completed, we begin discussing quality of life issues, including vaginal discomfort and other symptoms. I would consult with her oncologist, and if there were no objections, I would prescribe vaginal estrogen.”
Because vaginal estrogen is minimally absorbed, it is generally considered low risk, even for patients with a cancer history.
Nguyen said decisions about systemic HRT require careful discussion among the patient and her care team.
“If a patient has been stable and cancer-free for some time, she may be a better candidate for systemic HRT,” he said. “Some cancers are hormone-sensitive, which may affect risk. Ultimately, we consider how much the symptoms are affecting her daily life.”
If I can’t or don’t want to take hormones, what other options do I have?
Every woman’s menopause experience is different. For those who choose not to use hormone therapy, nonhormonal options are available.
“Hormone therapy is effective, but it is not the only way to manage menopause symptoms,” Nguyen said. “If a patient cannot or prefers not to take hormones, there are still options. Nonhormonal lubricants can help with painful intercourse, and other medications may help with mood swings, hot flashes, and sleep disturbances.”
Nguyen said menopause care should be individualized and guided by open communication between patients and their healthcare providers. Whether a woman chooses HRT, nonhormonal treatments or a combination of approaches, the goal remains the same.
“We can find safe and effective ways to improve each woman’s quality of life,” he said. “With the right support and an individualized plan, women can manage menopause in a way that aligns with their health and personal preferences."
