Has your menstrual cycle suddenly become irregular? Or do you just feel a bloated, heavy feeling in your lower abdomen? Sometimes we think these are normal things, but today we are talking about a reason that may be a little worrying. This is a condition called Granulosa Cell Tumor (GCT). Don't be scared when you hear this name, it is very important to be aware of this.
Simply put, what is Granulosa Cell Tumor (GCT)?
Granulosa Cell Tumor (GCT) is a type of tumor that develops in the ovaries of women. As you know, the ovaries are a very important part of our female reproductive system. In addition to producing eggs, these ovaries also produce two female hormones called estrogen and progesterone.
The specialty of these GCT tumors is that they produce excessive amounts of the hormone estrogen . This is why various changes and symptoms appear in the body. Although these tumors can develop at any age, they are most commonly seen around the age of 50.
GCT is a very rare condition. It accounts for only 5% of all ovarian tumors. But it's important to be aware of it for your health.
Are these tumors malignant?
Yes, Granulosa Cell Tumor is a type of tumor that usually falls into the malignant category. But the most important thing you need to remember here is that most of these tumors grow very slowly . Because of this, there are more chances of detecting them in the early stages. If they are detected early, the results of treatment are also very good. So there is no need to worry.
Is there a difference between GCTs that develop in older people and younger people?
Yes, there is a slight difference. This condition is most commonly seen in older women. 95% of the patients diagnosed are well-developed older women.
However, if this tumor develops in a young person under the age of 30, it may be a type called Juvenile GCT . Sometimes this type of Juvenile GCT can grow a little faster than the type that develops in adults, and it may be slightly more likely to recur a few years after treatment.
What causes a GCT to form?
Experts still don't know exactly what causes this. But most of these tumors have a mutation, or change, in a gene called FOXL2 . The main function of this gene is to help granulosa cells grow healthy. So when there is a change in this gene, the cells can grow abnormally and form tumors like this.
Do you also have these symptoms?
The main symptom of a GCT is an increase in estrogen levels in the body. The symptoms that result from this can vary depending on your age.
- A young girl may show signs of puberty at an early age.
- In older women , the following symptoms are common.
| Symptom | Description |
|---|---|
| Irregular bleeding | Recurrent bleeding in women who have finished their menstrual cycle (after menopause) or abnormal uterine bleeding in young women. |
| Abdominal bloating | Enlargement or a feeling of swelling in the lower abdomen. |
| Changes in the menstrual cycle | Irregular or complete cessation of menstruation. |
| Breast pain | Breast pain or tenderness. |
| Lower abdominal pain | This usually only occurs if the cyst ruptures, which can cause sudden, severe pain. |
What complications can occur if left untreated?
If this condition is not treated in time, the risk of other health problems increases as estrogen levels in the body remain high.
| Possible complication | Simply put... |
|---|---|
| Endometrial Hyperplasia | Abnormal thickening of the inner wall of the uterus. |
| Uterine Cancer | Increased risk of developing uterine cancer cells. |
| Breast Cancer | The risk of breast cancer may also be slightly increased. |
| Infertility | Impact on the ability to have children. |
How do doctors diagnose this disease?
When you tell your doctor about the above symptoms, he or she will examine you and order several tests to confirm the condition.
- Imaging: This may involve a CT scan , MRI scan , or, most commonly , a transvaginal ultrasound , which is a scan done through the vagina.
- Blood Tests: These tests check for certain tumor markers, such as Inhibin, which is produced by GCTs. They also check for other conditions.
What are the treatment options?
The first and main treatment for GCT is surgery . Here, the surgeon tries to remove as much of the tumor as possible without damaging healthy tissue.
If you are young, not planning to have children, or are postmenopausal, your doctor may recommend an oophorectomy , which involves removing the entire ovary that contains the tumor. In some cases, a hysterectomy may also be necessary.
Determining the stage of cancer (staging)
After surgery, the "stage" is determined to see if the cancer has spread.
- Stage 1: The tumor is confined to the ovaries and has not spread.
- Stages 2 to 4: The cancer has spread (metastasized) to other parts of the body.
The good news is that 9 out of 10 GCT patients are diagnosed at stage 1 , when the cancer is confined to the ovaries. In such cases, surgery alone may be sufficient.
Depending on the size of the tumor and the risk of recurrence, other treatments may be recommended in addition to surgery.
- Chemotherapy
- Hormone therapy
- Radiation therapy
What happens after treatment?
After the tumor is removed, you will need to be under medical supervision for a long time, as these tumors can sometimes recur even after years . Therefore, your doctor will check you at regular intervals to make sure the tumor has not returned.
- Pelvic exams
- Blood tests for cancer markers
- Things like scans are used for this.
Is it possible to recover completely from this condition?
Yes, absolutely. Granulosa Cell Tumor can be completely cured, especially if detected early and surgically removed.
If the cancer is detected after it has spread to other parts of the body, the chances of a cure may be reduced. That's why we recommend that if you have symptoms of a GCT, see a doctor without delay .
Take-Home Message
- Granulosa Cell Tumor (GCT) is a rare, usually slow-growing cancerous tumor that forms in the ovaries.
- This causes excessive production of the hormone estrogen, which causes symptoms such as irregular bleeding and bloating.
- If a person whose menstrual cycle has stopped is bleeding again, or has any other unusual symptoms, do not delay. See a doctor immediately.
- If detected in the early stages, it can be completely cured with surgery.
- Long-term medical monitoring is very important, as these tumors can recur even after treatment.
