Endometrial cancer, also known as uterine cancer, is a type of cancer that develops in the lining of the uterus, known as the endometrium. It is the most common type of uterine cancer and primarily affects women during or after menopause.
Understanding the causes, symptoms, and treatment options for endometrial cancer is crucial for early detection and effective management of this disease.
Causes of Endometrial Cancer
Endometrial cancer occurs when the cells in the endometrium undergo abnormal growth and multiply rapidly. While the exact cause of this abnormal cell growth is unclear, certain factors may increase the risk of developing endometrial cancer:.
1. Hormonal Imbalances
An imbalance in the hormones estrogen and progesterone can lead to the excessive growth of the endometrium, increasing the risk of developing endometrial cancer.
Conditions such as polycystic ovary syndrome (PCOS) or estrogen hormone replacement therapy without progesterone can contribute to hormonal imbalances.
2. Obesity
Obese women have a higher risk of developing endometrial cancer due to the higher levels of estrogen produced by adipose tissues. Fat cells can also produce hormones and growth factors that promote abnormal cell growth in the endometrium.
3. Age and Menopause
Endometrial cancer primarily affects women after menopause. The risk increases with age, particularly in women over the age of 50.
This may be because the hormonal changes during menopause disrupt the balance between estrogen and progesterone, leading to abnormal cell growth.
4. Family History
Having a family history of endometrial cancer or certain hereditary conditions, such as Lynch syndrome, can increase the risk of developing this disease.
Lynch syndrome is a genetic disorder that increases the risk of various types of cancer, including endometrial cancer.
5. Diabetes
Women with diabetes, particularly those with uncontrolled blood sugar levels, are at a higher risk of developing endometrial cancer.
The excess insulin or insulin resistance associated with diabetes can promote cell division and increase estrogen levels, leading to the development of endometrial cancer.
Symptoms of Endometrial Cancer
Endometrial cancer may cause various symptoms, although not all women may experience them. It is important to be aware of these symptoms and seek medical attention if they persist:.
1. Abnormal Vaginal Bleeding
One of the most common symptoms of endometrial cancer is abnormal vaginal bleeding, particularly after menopause. This may include bleeding between periods, prolonged periods, or heavy vaginal bleeding.
2. Pelvic Pain
Some women with endometrial cancer may experience pelvic pain that is unrelated to menstruation or other conditions. The pain may be dull or sharp and may worsen over time.
3. Painful Urination
Endometrial cancer can sometimes cause pain or discomfort during urination. This symptom may indicate the presence of cancer cells in the nearby tissues of the bladder or urinary tract.
4. Painful Intercourse
Women with endometrial cancer may experience pain during sexual intercourse. This may be due to the presence of tumors or the spread of cancer to surrounding tissues.

5. Unexplained Weight Loss
Sudden and unexplained weight loss can be a sign of advanced endometrial cancer. The cancer cells may cause a decrease in appetite or interfere with the body’s ability to absorb nutrients.
Diagnosis and Treatment Options
Early detection and accurate diagnosis are crucial for successful treatment of endometrial cancer. If endometrial cancer is suspected, the following diagnostic tests may be performed:.
1. Transvaginal Ultrasound
A transvaginal ultrasound is a non-invasive imaging test that uses sound waves to create images of the uterus. It can help detect abnormalities in the thickness or structure of the endometrium.
2. Biopsy
A biopsy involves the removal of a small sample of tissue from the endometrium for examination under a microscope. This allows for the identification of abnormal cells and the determination of whether they are cancerous.
3. Hysteroscopy
A hysteroscopy is a procedure that involves the insertion of a thin, lighted tube called a hysteroscope into the uterus. It allows for the direct visualization of the endometrium and can be used to collect biopsy samples or remove small growths.
4. Imaging Tests
Imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans may be performed to determine the extent of the cancer and whether it has spread to other organs.
5. Treatment Options
The treatment of endometrial cancer depends on several factors, including the stage of the cancer, the woman’s overall health, and her desire for future childbearing. The main treatment options for endometrial cancer include:.
1. Surgery
Surgery is the most common treatment for endometrial cancer. It involves the removal of the uterus (hysterectomy) and may also include the removal of the fallopian tubes, ovaries, and nearby lymph nodes.
In some cases, minimally invasive procedures such as laparoscopy or robot-assisted surgery may be used.
2. Radiation Therapy
Radiation therapy involves the use of high-energy X-rays or other types of radiation to kill cancer cells or prevent their growth.
It may be used before surgery to shrink tumors, after surgery to destroy any remaining cancer cells, or as the primary treatment for women who are not candidates for surgery.
3. Chemotherapy
Chemotherapy uses drugs to destroy cancer cells throughout the body. It may be administered orally or intravenously and is often used in advanced stages of endometrial cancer or when the cancer has spread to other organs.
4. Hormone Therapy
Hormone therapy involves the use of medications to block the effects of estrogen on the growth of cancer cells. It is typically used in women with advanced or recurrent endometrial cancer.
5. Targeted Therapy
Targeted therapy uses drugs that specifically target certain molecules or genetic mutations involved in the growth and spread of cancer cells.
It may be used in combination with other treatments or as a standalone therapy for advanced endometrial cancer.
Conclusion
Endometrial cancer is a common type of cancer that primarily affects women after menopause. Understanding the causes, recognizing the symptoms, and seeking early diagnosis are essential for effective treatment and improved outcomes.
With advancements in medical technology and various treatment options available, the prognosis for women diagnosed with endometrial cancer continues to improve.
