Menopause is a natural process that usually occurs in women between the ages of 45 and 55. However, some women experience menopause earlier due to medical interventions. Medically induced menopause can result from treatments such as surgery, chemotherapy, radiation, or hormone therapy. Unlike natural menopause, which develops gradually, medically induced menopause often happens suddenly, causing a rapid decrease in hormones like estrogen, progesterone, testosterone, and other androgens. This abrupt change can intensify menopause symptoms.
“It’s like flipping a switch,” said Lauren Oshry, M.D., a breast medical oncologist at Sylvester Comprehensive Cancer Center, part of UHealth – University of Miami Health System. “Patients don’t get the gradual hormonal decline that comes with natural menopause. Instead, they’re suddenly dealing with hot flashes, mood swings and other symptoms without warning.”
There are several reasons why menopause may be medically induced. It is sometimes a side effect of cancer treatments such as chemotherapy or radiation. In other cases, it is an intentional part of treatment or a method to reduce cancer risk. For hormone-sensitive cancers like breast cancer, lowering estrogen and progesterone levels can help prevent recurrence. This is often achieved through medications or surgical removal of the ovaries. Women with certain genetic mutations may choose preventive surgery to reduce their risk of ovarian or breast cancer. Medically induced menopause may also be used to treat severe endometriosis or to manage fibroids and heavy menstrual bleeding when other treatments are not effective.
Roxana Chaviano, a breast cancer survivor, experienced medically induced menopause as part of her treatment plan. After chemotherapy and radiation, she received monthly hormone injections to suppress her ovaries’ production of hormones. “It was a lot to take in,” Roxana said. “I wasn’t just dealing with cancer. I was suddenly in menopause at 30.”
The side effects of medically induced menopause are similar to those of natural menopause but may appear more quickly and intensely. Common symptoms include hot flashes, night sweats, vaginal dryness, mood changes, sleep disturbances, decreased libido, cognitive changes such as brain fog, bone density loss, and increased risk of osteoporosis and cardiovascular changes.
“Patients often tell me they feel like their bodies betrayed them,” Dr. Oshry said. “It’s not just physical — it’s emotional. Especially for younger women, the loss of fertility and hormonal shifts can be overwhelming.”
To manage medically induced menopause, experts recommend several strategies. Patients should talk to their health care team before starting treatments that could cause menopause to discuss fertility preservation and symptom management options. “Planning ahead is key,” said Dr. Oshry. “We want patients to feel empowered, not blindsided.”
Maintaining bone health is important since estrogen loss can weaken bones. Calcium and vitamin D supplements and weight-bearing exercise are recommended preventive measures. Regular bone-density scans can help detect early bone loss.
Sexual and genitourinary health may also be affected by menopause. Symptoms such as vaginal dryness and urinary issues can often be improved with moisturizers, lubricants, or pelvic floor therapy. Sylvester’s MUSIC — Menopause Urogenital Sexual Health and Intimacy Clinic — program addresses these concerns in cancer survivors.
Cardiovascular health should also be monitored because estrogen supports heart function. Maintaining a healthy lifestyle and monitoring blood pressure and cholesterol are advised.
Exercise is beneficial for bone health, heart health, cognition, and mood during menopause. Programs like Sylvester’s Believe in You training and wellness program offer support for cancer survivors starting or maintaining exercise routines.
Emotional support is also important. Therapy, support groups, and peer networks can help individuals cope with the psychological effects of early menopause. Roxana found support in community breast cancer groups.
Staying informed about treatment options and symptom management empowers patients to better handle medically induced menopause.
“Menopause — whether natural or medically induced — is a transition, not an ending,” said Dr. Oshry. “It’s our job to help patients move through it with confidence, compassion and clarity.”
