Endometrial Cancer
Endometrial 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 most often occurs after menopause, although it can develop at any age.
What causes endometrial cancer?
The exact causes of endometrial cancer are not fully understood, but several factors are linked to its development:
- Hormonal imbalance - An increase in estrogen levels without sufficient progesterone can promote the growth of the endometrial lining. Conditions like polycystic ovary syndrome (PCOS) and estrogen-secreting tumors also contribute to this imbalance.
- Obesity - Excess body fat can lead to higher estrogen levels in the body.
- Age - The risk of endometrial cancer increases with age, especially after menopause.
- Diabetes- Women with diabetes, particularly those who are overweight, are at a higher risk of the disease.
- Genetic factors - A family history of endometrial, ovarian, or colorectal cancer can increase the risk of developing endometrial cancer. Certain genetic syndromes, such as Lynch syndrome (hereditary nonpolyposis colorectal cancer), are also linked to endometrial cancer.
- Menstrual history - Women with irregular menstrual cycles or who have never been pregnant may be at higher risk.
- Hormone replacement therapy (HRT) - Taking estrogen alone (without progesterone) during menopause may increase the risk, especially in women.
- Use of medication - Certain medications can increase the risk of endometrial cancer, though the benefits of their use often outweigh this risk.
Symptoms of Endometrial Cancer
Symptoms of endometrial cancer can vary, but common signs to watch for include:
- Vaginal bleeding -This may include bleeding between periods, heavy menstrual bleeding, or bleeding after menopause;
- Pelvic pain - Persistent pain in the pelvic area that is not related to menstrual pain;
- Changes in menstrual cycle - Such as irregular menstrual periods;
- Unexplained weight loss;
- Pain or discomfort during intercourse;
- Watery vaginal discharge or any unusual discharge, especially if it is blood-stained.
- Fatigue - Severe tiredness that does not go away with rest.
Diagnosis of Endometrial Cancer
The diagnosis of endometrial cancer involves a pelvic exam and imaging studies. Ultrasound may be used to visualize the uterus and assess the thickness of the endometrial lining, while, if necessary, CT (computed tomography) or MRI (magnetic resonance imaging) scans can help check the extent and spread of the cancer.
An essential step in diagnosis is an endometrial biopsy—a procedure where a small sample of endometrial tissue is taken and examined for cancer cells.
Treatment of Endometrial Cancer
Treatment for endometrial cancer depends on factors such as the stage and grade of the cancer and the patient’s overall health. Common treatment options include surgery (hysterectomy and lymphadenectomy), chemotherapy, hormone therapy, or radiation therapy.
Regular follow-up is crucial to monitor for recurrence and manage any side effects of treatment.
