What percentage of women older than 35 are reported to have uterine leiomyomas?

The correct answer indicates that 20-40 percent of women older than 35 are reported to have uterine leiomyomas, also known as fibroids. This range reflects various studies and clinical findings that demonstrate the prevalence of fibroids in women as they age, particularly past the reproductive years, when hormone levels fluctuate and predominantly estrogen plays a role in fibroid development.

Understanding that 20-40 percent is a commonly accepted statistic helps to underscore the significant impact that uterine leiomyomas can have on a population. These benign tumors of the uterus are especially prevalent in women over 35 due to reproductive history and hormonal influences. Factors such as race and hormonal exposure may also contribute to variations in these statistics, but the 20-40 percent range is a reliable estimate for this demographic.

The other options present figures that either understate or overstate the prevalence of uterine leiomyomas in women older than 35. Data from various studies support the selected range, making it the most accurate representation of the condition's prevalence in this age group.
