What is the Difference Between Fibroid and Ovarian Cyst?

🆚 Go to Comparative Table 🆚

Fibroids and ovarian cysts are both growths that can occur in the female reproductive system, but they differ in their composition, location, and symptoms. Here are the main differences between the two:

  1. Location: Fibroids develop on the uterus, while cysts occur in the ovaries.
  2. Composition: Fibroids are noncancerous masses made of muscle and fibrous tissue, and they may develop inside or outside the uterine wall. In contrast, cysts are fluid-filled sacs that develop on the outside of the ovary.
  3. Symptoms: Fibroids can cause heavy menstrual bleeding, abdominal pain, and pelvic pain. Ovarian cysts, on the other hand, may cause abdominal pain on only one side, pain during sex, and irregular menstrual cycles.
  4. Causes: The exact cause of uterine fibroids is unclear, but female sex hormone levels and genetics may play a role. Ovarian cysts can form when one of the follicles responsible for releasing the egg fails to open.

Both fibroids and cysts can be detected through an ultrasound scan, and treatment depends on the symptoms, plans for a family, and the size and location of the growth. In some cases, surgical intervention may be necessary.

Comparative Table: Fibroid vs Ovarian Cyst

Here is a table comparing the differences between fibroids and ovarian cysts:

Fibroids Ovarian Cysts
Noncancerous growths that develop in the uterus Fluid-filled sacs that develop in or on the ovaries
Made of smooth muscle tissue Composed of fluid
Can cause pelvic pain and abnormal uterine bleeding Can cause pelvic pain and abnormal uterine bleeding
Affect 33% of women during their childbearing years, and 70-80% of women by age 50 Common, especially among women before menopause
Diagnosed through ultrasound Diagnosed through ultrasound
50% of all women will have fibroids by the time they reach 50 Most common type of ovarian cyst is a follicular cyst, which usually resolves on its own
Some cysts can become cancerous in rare situations, such as dermoid cysts Rarely become cancerous

Both fibroids and ovarian cysts are common in females, especially before menopause. Fibroids are noncancerous tumors that form in the muscular wall of the uterus, while ovarian cysts are fluid-filled pouches that develop in or on the ovaries. They can both present with similar symptoms, such as pelvic pain and abnormal uterine bleeding, and in some cases, can affect fertility.
