Know the Signs: Understanding Gestational Trophoblastic Disease (GTD)

Most pregnancies develop normally, but in rare cases, abnormal tissue can form inside the uterus instead of a healthy pregnancy. This condition is known as Gestational Trophoblastic Disease (GTD).

GTD is a rare pregnancy-related condition that affects approximately 1 in 1,000 pregnancies in the United States. While some forms of GTD can become cancerous, most are not cancerous and are highly treatable.

Because GTD is uncommon, many women have never heard of it until they or someone they love receives a diagnosis. Understanding the signs and symptoms can help women know when to seek medical care and ask questions.

What Is Gestational Trophoblastic Disease?

Gestational Trophoblastic Disease (GTD) is a group of rare conditions that develop from cells that normally help form the placenta during pregnancy. These cells grow abnormally, creating tissue or tumors inside the uterus.

Some forms of GTD remain non-cancerous, while others can develop into a type of cancer called Gestational Trophoblastic Neoplasia (GTN). Fortunately, GTD is one of the most treatable gynecologic conditions, and outcomes are often excellent when it is diagnosed and treated appropriately.

What Are the Signs and Symptoms?

Many symptoms of GTD can resemble those of pregnancy or other gynecologic conditions, which is why it is important to pay attention to changes in your body and speak with your healthcare provider if something feels unusual.

Common signs and symptoms may include:

  • Vaginal bleeding during or after pregnancy
  • Severe nausea and vomiting
  • Pelvic pain or pressure
  • A uterus that measures larger than expected during pregnancy
  • Swelling of the hands and feet early in pregnancy
  • Vaginal bleeding that continues after a miscarriage, abortion, or childbirth

In some cases, GTD may also affect the thyroid, causing symptoms such as a rapid heartbeat, shakiness, sweating, or unexplained weight loss.

Why Awareness Matters

Because GTD is rare, many women are unfamiliar with the condition and may not recognize when symptoms warrant medical attention.

Symptoms such as abnormal bleeding or prolonged recovery after a pregnancy loss can have many causes, but they should never be ignored. Early evaluation can help identify the cause and, if necessary, lead to earlier diagnosis and treatment.

Knowing what is normal for your body—and speaking up when something feels different—can make a meaningful difference.

How Is GTD Diagnosed?

Healthcare providers may use several tools to diagnose GTD, including:

  • A pelvic examination
  • Ultrasound imaging
  • Blood tests to measure pregnancy hormone (hCG) levels

Because GTD is often associated with elevated hCG levels, blood testing and ultrasound are typically the first steps in diagnosis.

Who is at Risk?

Anyone who becomes pregnant can develop GTD, but certain factors may increase risk, including:

  • Pregnancy before age 20 or after age 35
  • A previous molar pregnancy
  • A history of miscarriage

Having one or more risk factors does not mean you will develop GTD. Many women diagnosed with GTD have no known risk factors.

How Is GTD Treated?

Treatment depends on the type of GTD, whether it has spread, and a patient’s overall health and future fertility goals.

Treatment options may include:

  • Removal of abnormal tissue from the uterus
  • Chemotherapy
  • Surgery in certain situations
  • Radiation therapy in rare cases

Your healthcare team will recommend a treatment plan tailored to your specific diagnosis and needs.

The good news is that GTD is often highly responsive to treatment, and outcomes are generally very favorable.

What Happens After Treatment?

Follow-up care is an important part of GTD treatment.

After treatment, healthcare providers typically monitor hCG levels through regular blood tests to ensure the abnormal cells have been eliminated and to watch for any signs of recurrence.

Although GTD can sometimes return, ongoing monitoring helps healthcare teams identify and address problems early.

Can I Have Children After GTD?

For many women, the answer is yes.

One of the most common concerns after a GTD diagnosis is whether future pregnancy is possible. The encouraging news is that many women treated for GTD go on to have healthy pregnancies and healthy babies.

Your healthcare team will discuss how long to wait before trying to conceive and provide guidance based on your treatment and follow-up results.

When Should You Contact a Healthcare Provider?

Talk with your healthcare provider if you experience:

  • Vaginal bleeding that seems unusual
  • Persistent bleeding after pregnancy, miscarriage, or childbirth
  • Severe nausea and vomiting
  • Pelvic pain or pressure
  • Symptoms that concern you during or after pregnancy

While these symptoms are often caused by conditions other than GTD, they should always be evaluated by a healthcare professional.

The Bottom Line

Gestational Trophoblastic Disease is rare, but awareness matters.

Most forms of GTD are highly treatable, and many women go on to live healthy lives and have future pregnancies after treatment. Understanding the signs, paying attention to changes in your body, and speaking with your healthcare provider when something feels unusual can help lead to earlier diagnosis and care.

If you have questions about GTD or other gynecologic cancers, talk with your healthcare provider and learn more through the Foundation for Women’s Cancer.
