What is Endometrial Cancer?
Endometrial cancer, also known as uterine cancer, begins in the lining of the uterus called the endometrium. It is the most common type of uterine cancer and predominantly affects women after menopause. This type of cancer can be categorized into two main types: endometrioid adenocarcinoma, which is the more common and less aggressive form, and non-endometrioid adenocarcinoma, which is rarer and typically more aggressive.
What are the Risk Factors?
Several risk factors are associated with the development of endometrial cancer. These include:
-
Age: Most cases occur in women who are over 50 years old.
-
Obesity: Excessive body fat can increase estrogen levels, which is a risk factor.
-
Hormone Replacement Therapy (HRT): Estrogen-only HRT can elevate the risk.
-
Genetics: Conditions like Lynch syndrome and a family history of uterine cancer can increase risk.
-
Menstrual History: Early onset of menstruation and late menopause can elevate risk due to prolonged estrogen exposure.
What are the Symptoms?
Common symptoms of endometrial cancer include:
-
Abnormal Vaginal Bleeding: This is the most common symptom, especially post-menopause.
-
Pelvic Pain: Discomfort or pain in the pelvis can be a sign.
-
Unusual Discharge: Non-bloody discharge can also indicate the presence of cancer.
-
Pain During Intercourse: This can sometimes be a symptom of endometrial cancer.
How is it Diagnosed?
Diagnosis typically involves several steps:
-
Physical Examination: A pelvic exam can help in detecting abnormalities.
-
Imaging Tests: Ultrasound, particularly transvaginal ultrasound, can be useful.
-
Biopsy: An endometrial biopsy is the definitive way to diagnose this cancer.
-
Hysteroscopy: This involves inserting a thin, lighted tube into the uterus to examine it and take tissue samples.
What are the Treatment Options?
Treatment depends on the stage and type of cancer, as well as the patient’s overall health. Common treatment modalities include:
-
Surgery: Often the first line of treatment, involving a hysterectomy to remove the uterus.
-
Radiation Therapy: Used to kill cancer cells or shrink tumors.
-
Chemotherapy: Often used if the cancer has spread or is aggressive.
-
Hormone Therapy: Can be effective in certain types of endometrial cancer that are hormone-sensitive.
What is the Prognosis?
The prognosis for endometrial cancer is generally favorable if detected early. The 5-year survival rate for early-stage endometrial cancer is quite high. However, the prognosis worsens if the cancer has spread to other parts of the body. Early detection through regular medical check-ups and being aware of symptoms is crucial for improving outcomes.
How Can It Be Prevented?
While not all cases can be prevented, certain measures can reduce risk:
-
Maintaining a Healthy Weight: Helps in regulating estrogen levels.
-
Regular Exercise: Can lower the risk of many cancers, including endometrial cancer.
-
Birth Control Pills: Long-term use of oral contraceptives has been shown to reduce the risk.
-
Managing Diabetes: Proper control of diabetes can help lower risk.
-
Genetic Counseling: For those with a family history, genetic counseling and regular screenings are advisable.
Importance of Follow-Up Care
After treatment, regular follow-up care is essential to monitor for any signs of recurrence. This typically includes physical exams, imaging tests, and sometimes blood tests. Being vigilant about follow-up care can significantly improve long-term outcomes.
