What Is a Fibroid Tumor in Uterus?

They consist mostly of smooth muscle tissue. They can be of different sizes, and there can be more than one fibroid tumors in a uterus. Fibroid tumors range from small, barely visible myomas, to huge tumors larger than a baseball.

Types of Fibroid Tumors

There are 4 kinds of fibroid tumors, and it’s possible to have more than one kind of myomas.

  • Intramural fibroid tumors are the most common kind. They grow in the wall of the uterus.
  • Subserosal fibroid tumors grow on the outside of the uterus. As they grow larger, they can cause pain due to their size or press on organs like bladder, for example. This can lead to other common symptoms of subserosal myomas like frequent urination (among other symptoms).
  • Submucosal fibroid tumors grow just underneath the uterine lining and can fill the uterus cavity leading to heavy bleeding, unusually long periods, and in some cases, anemia.
  • Pedunculated fibroid tumors grow on small stalks inside or outside the uterus.
