Pregnancy tumors are growths that can occur during pregnancy. They are also known as fibroids, myomas, or leiomyomas. While these tumors are usually benign (non-cancerous), they can sometimes be cancerous. Pregnancy tumors are most commonly found in the uterus (womb).

However, they can also occur in other parts of the body, such as the breast, ovaries, or cervix. Pregnancy tumors are relatively common. It is estimated that up to 30% of women have fibroids, and up to 10% have myomas.

Symptoms of Pregnancy Tumors:

Pregnancy tumors are usually asymptomatic (do not cause symptoms). However, some women may experience one or more of the following symptoms:

1. Bleeding:

Fibroids can cause heavy bleeding, particularly during menstruation. Myomas can also cause bleeding between periods.

2. Pain:

Fibroids can sometimes cause pain or pressure in the pelvic area. Myomas can also cause pain during sex.

3. Miscarriage:

In rare cases, pregnancy tumors can cause miscarriage.

4. Preterm Labor:

In rare cases, pregnancy tumors can cause preterm labor (labor that occurs before 37 weeks of pregnancy).

5. Placental Abruption:

In rare cases, pregnancy tumors can cause placental abruption (when the placenta separates from the uterus before delivery).

If you have any of these symptoms, please speak to your doctor.

How are Pregnancy Tumors diagnosed?

Pregnancy tumors are typically diagnosed during a routine pelvic exam. Your doctor will feel for any unusual growths in your uterus.

In some cases, an ultrasound may also be used to confirm the diagnosis.

Treatment for Pregnancy Tumors:

  • Most pregnancy tumors do not require treatment. In most cases, they will go away on their own after delivery.
  • If a pregnancy tumor is causing symptoms or complications, treatment may be necessary. Treatment options include surgery, medication, or radiation therapy.
  • Surgery is the most common form of treatment for pregnancy tumors. Myomas can be removed through a procedure called a myomectomy. Fibroids can be removed through a procedure called a fibroidectomy.
  • In some cases, it may not be possible to remove the entire tumor. In these cases, medication or radiation therapy may be used to shrink the tumor.


Pregnancy tumors are usually benign (non-cancerous). However, in rare cases, they can be cancerous. If a pregnancy tumor is cancerous, it is important to get treatment as soon as possible. Treatment for cancerous pregnancy tumors may include surgery, radiation therapy, or chemotherapy.
