How Do You Check For Fibroids Tests And Exams?

If you are experiencing heavy periods, pelvic pressure, or lower back pain, your doctor may want to check for uterine fibroids. These noncancerous growths in the uterus are common, but they do not always cause symptoms. To check for fibroids, a doctor typically starts with a pelvic exam and then confirms the finding with imaging, most often an ultrasound. The combination of a physical exam and imaging gives the clearest picture of whether fibroids are present, their size, and their location.

What Happens During a Pelvic Exam for Fibroids?

The pelvic exam is usually the first step. Your doctor will feel the uterus and surrounding structures from the outside and inside. This allows them to detect an enlarged uterus or an irregular shape that fibroids can cause.

During the exam, the doctor inserts two gloved fingers into the vagina while pressing on the abdomen with the other hand. This is called a bimanual exam. It helps the doctor assess the size and position of the uterus. If the uterus feels larger than expected or has a lumpy texture, fibroids may be present.

A pelvic exam alone cannot confirm fibroids. It can only suggest they might be there. Other conditions, such as ovarian cysts or adenomyosis, can cause similar findings. For this reason, imaging is needed for a definitive diagnosis.

How Do You Check For Fibroids Tests And Exams Using Ultrasound?

Ultrasound is the standard imaging test for fibroids. It uses sound waves to create a picture of the uterus on a screen. It is safe, painless, and does not involve radiation.

There are two ways to perform this ultrasound. A transabdominal ultrasound involves moving a wand over the lower belly. A transvaginal ultrasound uses a smaller wand inserted into the vagina. The transvaginal approach provides a closer and clearer view of the uterus, especially for small fibroids.

Ultrasound can show the number of fibroids, their size, and where they are located. This information matters because fibroids that bulge into the uterine cavity can cause different symptoms than those growing on the outer surface of the uterus. The ultrasound report will describe fibroids by their location, such as submucosal, intramural, or subserosal.

When Is an MRI Recommended for Fibroids?

An MRI is not the first test most women receive. It is usually ordered when the ultrasound results are unclear or when surgery is being planned. MRI stands for magnetic resonance imaging and uses magnets and radio waves to create detailed images.

An MRI provides a much more precise map of the uterus than an ultrasound. It can show the exact size of each fibroid and how deep they are in the uterine wall. This detail is valuable before a myomectomy, which is surgery to remove fibroids while keeping the uterus.

MRI can also distinguish fibroids from other types of pelvic masses. If a growth looks unusual on ultrasound, an MRI can help clarify what it is. Some research suggests that MRI detects small fibroids that ultrasound may miss, though most fibroids found on ultrasound do not require an MRI.

What Other Tests Are Used to Evaluate Fibroids?

In certain situations, a doctor may recommend additional tests. These are not routine for every patient, but they provide specific information in specific circumstances.

Hysterosonography is a special ultrasound where sterile fluid is placed into the uterine cavity through a thin tube. The fluid expands the cavity, making it easier to see fibroids that bulge inward. This test is especially useful for evaluating submucosal fibroids, which can cause heavy bleeding and fertility problems.

Hysteroscopy is a procedure where a small camera is inserted through the cervix into the uterus. It allows the doctor to see the uterine cavity directly. A hysteroscopy can confirm the presence of submucosal fibroids and can sometimes be used to remove them at the same time. This is performed in an office or operating room, depending on the complexity.

Blood tests are not used to diagnose fibroids. However, a complete blood count may be ordered to check for anemia if heavy menstrual bleeding is a concern. Anemia is a low red blood cell count and is a common complication of heavy periods caused by fibroids.

Can a Biopsy Be Needed to Rule Out Other Conditions?

A biopsy is not a standard test for fibroids. Imaging is usually sufficient to make the diagnosis. However, a biopsy may be recommended if the imaging looks unusual or if the doctor suspects a different condition.

An endometrial biopsy takes a small sample of the uterine lining. It is used to check for abnormal cells or cancer. Fibroids themselves are almost always benign, meaning they are not cancerous. But the symptoms of fibroids can overlap with other conditions, so a biopsy helps clarify the cause in specific cases.

If you have unusual bleeding patterns or postmenopausal bleeding, a biopsy is more likely to be part of the evaluation. This is because the risk of uterine cancer increases after menopause, and fibroids are less likely to be the sole explanation for new bleeding at that age.

What Can You Expect After the Tests?

After the imaging is complete, your doctor will review the results with you. The findings will determine whether treatment is needed and what options are appropriate. Many women with fibroids need no treatment at all.

Fibroids that cause no symptoms can be monitored with periodic exams and ultrasounds. Your doctor may suggest checking the size again in six months or a year to see if they are growing. Fibroids that cause heavy bleeding, pain, or pressure may warrant treatment.

Treatment options range from medications that manage symptoms to procedures that remove or shrink fibroids. Surgery, such as hysterectomy or myomectomy, is reserved for more significant cases. The choice depends on your symptoms, your age, whether you want to have children, and the size and location of the fibroids.

How Accurate Are These Tests at Finding Fibroids?

Ultrasound is highly accurate for detecting fibroids that are large enough to cause symptoms. It is less reliable for very small fibroids or those in difficult positions. Studies show that transvaginal ultrasound is particularly effective at identifying fibroids that affect the uterine cavity.

MRI is considered the most accurate imaging method for fibroids. It provides the most complete picture of the uterus and is the gold standard for surgical planning. However, it is more expensive and not necessary for every patient.

No test is perfect. Fibroids can be missed, especially if they are small or if the uterus is enlarged for other reasons. If symptoms persist but initial tests are normal, a repeat ultrasound or an MRI may be warranted. Persistent symptoms should always be discussed with your doctor rather than dismissed.
