About 20-80 percent of women develop fibroids by the age of 50.

There are four types of fibroids.

  • Intramural: Fibroids grow into the uterine wall. These are the most common type.
  • Subserosal: They grow on the outside of the uterine wall.
  • Pedunculated: These types grow on stalks or stems. The stems are attached to the wall and can grow outside or inside of the uterine cavity.
  • Submucosal: Fibroids grow below the thin layer of tissue found in the uterus. They can protrude into the uterine cavity and are the rarest type.


1. What Are Fibroids?

Fibroids are smooth muscle tumors that grow in the uterus. They are benign, which means non-cancerous. Other terms used for the growth might include uterine leiomyomas or uterine fibroids. These masses range in size from very small to as large as a cantaloupe. Most of the time, fibroids do not cause any complications.
