Adnexal Mass Statistics
Some people use statistics to try to figure out their chances of getting cancer or of being cured. But statistics show what happens with large groups of people. Since no two people are alike, statistics cannot show what will happen to an individual.
These are some 2005 statistics on adnexal masses. They come from the American Cancer Society:
- Adnexal masses are found in women of all ages—from fetuses to the elderly. They are most likely to be malignant in girls younger than 15.
- Usually these masses are functional cysts. These disappear on their own and need no treatment.
- The chance you will develop an adnexal mass that’s malignant is about 1.5 percent over the course of your life.
