Oh ya this Angmoh the best woman mentioned one of the doctors wrongly used hormone treatment on her that worsened the cancer.
Hormone factors
A woman's hormone balance plays a part in the development of most endometrial cancers. Many of the risk factors for endometrial cancer affect estrogen levels. Before menopause, the ovaries are the major source of the 2 main types of female hormones -- estrogen and progesterone.
The balance between these hormones changes each month during a woman's menstrual cycle. This produces a woman's monthly periods and keeps the endometrium healthy. A shift in the balance of these hormones toward more estrogen increases a woman's risk for endometrial cancer.
After menopause, the ovaries stop making these hormones, but a small amount of estrogen is still made naturally in fat tissue. Estrogen from fat tissue has a bigger impact after menopause than it does before menopause.
Estrogen therapy
Treating the symptoms of menopause with hormones is known as menopausal hormone therapy (or sometimes hormone replacement therapy). Estrogen is the major part of this treatment. Estrogen treatment can help reduce hot flashes, improve vaginal dryness, and help prevent the weakening of the bones (osteoporosis) that can occur with menopause.
But using estrogen alone (without progesterone) can lead to endometrial cancer in women who still have a uterus. To lower that risk, a progestin (progesterone or a drug like it) must be given along with estrogen. This is called combination hormone therapy.
Women who take progesterone along with estrogen to treat menopausal symptoms do not have an increased risk of endometrial cancer. Still, taking this combination increases a woman's chance of developing breast cancer and also increases the risk of serious blood clots.
If you are taking (or plan to take) hormones after menopause, it's important to discuss the possible risks (including cancer, blood clots, heart attacks, and stroke) with your doctor.
Like any other medicine, hormones should be used at the lowest dose needed and for the shortest possible time to control symptoms. As with any other medicine you take for a long time, you’ll need to see your doctor regularly. Experts recommend yearly follow-up pelvic exams. If you have any abnormal bleeding or discharge from your vagina you should see a health care provider right away. (Do not wait until your next check-up).
