Endometrial cancer: risk factors, symptoms, diagnosis, and treatment
Complete information about risk factors, symptoms, diagnosis, and treatment of endometrial cancer.
The uterine cavity is lined by three layers: the peritoneal serosa, the myometrium, and the endometrium (the innermost layer). The endometrium is a mucous membrane whose main function is to allow the implantation of a fertilized egg. When fertilization or implantation fails, this tissue sheds, giving rise to menstruation. The endometrium subsequently regenerates to begin a new menstrual cycle.
The most common alterations that affect the endometrium are: endometrial polyps, submucosal fibroids, endometrial hyperplasia and endometrial cancer.
Today we will focus on the latter, which is more prevalent in developed countries and usually occurs a few decades after the onset of menopause. associated with excessive exposure to estrogen or an imbalance in another hormone called progesterone.
Risk factors associated with endometrial cancer
Endometrial cancer can occur in both premenopausal women (20%) and postmenopausal women (80%). The most commonly affected age is between 50 and 59 years., but it is also common to see cases in women under 40 years of age.
Generally, it is a tumor that can give suspicious symptoms in early stages of the disease. This situation, combined with appropriate periodic gynecological check-ups, allows for a very favorable prognosis in most cases.
Most women with endometrial cancer have a history of elevated estrogen levels accompanied by insufficient levels of estrogen's natural opponent, progesterone.
Elevated estrogen levels and, therefore, an increased risk of suffering from this disease may be due to:
- Obesity, especially >15 kg overweight.
- Estrogen-containing medications.
- Nulliparous women. That is, those who have never become pregnant.
- Sterility or inability to become pregnant.
- Premature menarche: the onset of menstruation at a very early age.
- Late menopause: cessation of menstruation at a very late age.
- Arterial hypertension.
- Syndrome polycystic ovary.
- Additionally, women with a history of endometrial polyps, those using estrogen hormone replacement therapy (if not taking regular progesterone at the same time), and those with diabetes are at increased risk of developing endometrial cancer.
- The drug tamoxifen, used to treat breast cancer, may also increase the risk of endometrial cancer.
Endometrial cancer
Symptom
- El abnormal vaginal bleeding -bleeding between periods or after menopause- is one of the most common symptoms that can detect endometrial cancer.
- Also anemia, caused by chronic blood loss, especially if the patient has ignored the symptoms of prolonged or abnormally frequent menstrual bleeding.
- Lower abdominal pain or intrapelvic cramps.
- Pain during sex.
- Whitish or colorless vaginal discharge in postmenopausal women.
These symptoms can be caused by other conditions, so it's very important to see a gynecologist as soon as possible if you detect any of them.
Diagnosis
The diagnosis of endometrial cancer consists of various phases.
It can be suspected based on the clinical picture, an altered cytology result, or endometrial thickening visible on vaginal ultrasound.
After this it is essential to carry out a diagnostic hysteroscopy with biopsy and pathological examination. The study should be completed with a pelvic-abdominal CT scan and/or magnetic resonance imaging.
Treatment
The treatment of endometrial cancer is surgical.
- Removal of the uterus and ovaries by laparoscopy or abdominal surgery, known as total hysterectomy with double annexectomy; and also:
- Removal of the pelvic and para-aortic lymph nodes when the tumor extends beyond the endometrium, invading more than half of the myometrium.
- In advanced cases, surgery must be supplemented with radiotherapy. In even more advanced cases, hormone therapy and chemotherapy are necessary.
