A woman’s life expectancy is not affected by the removal of the uterus, but by the disease for which the uterus was removed. If the hysterectomy is for a benign disease, it does not affect life expectancy. If the hysterectomy is for a malignant disease, survival depends on the severity of the disease and can be months or even decades. Removal of the uterus for benign diseases including uterine fibroids, adenomyosis, endometrial hyperplasia, and benign cervical disease does not affect life expectancy after surgery. Among malignant diseases, endometrial cancer has a better prognosis, with 80% of women surviving for more than 5 years. The prognosis of cervical cancer is more related to the stage, most of the early stage can survive for more than 5 years, and on average, 50%-60% of women survive for more than 5 years. In contrast, ovarian cancer has the worst prognosis, with only 20-30% of women surviving for more than 5 years, and the average survival period is 2-3 years. In addition, simple hysterectomy does not include removal of the ovaries. Preservation of the ovaries after hysterectomy for benign disease theoretically does not affect hormone levels or age at menopause, in addition to life expectancy.
