What Is the Importance of Endometrial Cancer Screening?
Endometrial cancer is the most common gynecological cancer and an important health problem. It is most commonly seen in women after menopause. The uterus is connected to the cervix, which is the lower part of the uterus that opens into the vagina. Because of this connection, doctors can sometimes detect signs of endometrial cancer from cells shed from the uterus.
Endometrial cancer is usually diagnosed in women around the age of 60. Common symptoms include vaginal bleeding after menopause, bleeding between periods, and pelvic pain. It can be managed if noticed early. The number of new cases and deaths from endometrial cancer is increasing every year.
What Are the Risk Elements of Developing Endometrial Cancer?
Many things can increase the risk of endometrial cancer.
-
Taking Tamoxifen: This medicine is used to prevent breast cancer. Taking it for more than two years may increase the risk of uterine cancer, especially in older women after menopause.
-
Being Overweight or Obese: Women who are overweight have increased chances of getting endometrial cancer. The risk increases with body weight.
-
Eating Too Much Fatty Food: Diets high in unhealthy fats (like trans fats) may increase the risk.
-
Taking Estrogen Alone: Taking estrogen alone in hormone therapy, without progesterone, may raise the risk of developing endometrial cancer.
-
Late Menopause or Early Periods: Starting periods before age 12 or reaching menopause late means more menstrual cycles. This can increase the risk.
-
Inherited Colon Cancer (Lynch Syndrome): This genetic condition can increase the risk of endometrial cancer. Women with this condition may develop cancer at a younger age.
-
Other things that may increase risk include metabolic syndrome, family history, certain ethnic backgrounds, and genetic factors.
How Is Endometrial Cancer Screening Done?
There is no standard screening test to find endometrial cancer early. The presence of risk factors does not mean a woman will definitely get cancer. However, regular checkups can help doctors find problems early. For women with Lynch syndrome, doctors may recommend yearly endometrial sampling and vaginal ultrasound, even if they do not have symptoms. The tests used to check for endometrial cancer include:
-
Pelvic Exam: During this exam, the doctor checks the vagina, cervix, uterus, ovaries, and rectum. The doctor may use a gloved hand or a speculum. The doctor also gently checks the abdomen externally.
-
Papanicolaou (Pap) Test: The Pap test is mainly used to find cervical cancer, not endometrial cancer. Using a brush, cells are extracted from the cervix. Sometimes the test may show abnormal cells in the uterus, and further testing may then be needed.
-
Transvaginal Ultrasound (TVU): Transvaginal ultrasound uses sound waves to create pictures of the uterus. It helps doctors see the thickness and growth of the endometrium. It can also help find the area that may need a biopsy. Doctors may recommend yearly TVU screening for women with Lynch syndrome starting at age 25. Women taking Tamoxifen may also need this test if they have vaginal bleeding. However, there is no strong proof that TVU reduces deaths from endometrial cancer. About 85% of endometrial cancer cases are found at an early stage.
-
Endometrial Biopsy: A doctor takes a small sample of endometrial tissue. A thin tube, brush, or curette is passed through the cervix to collect the tissue. After that, a pathologist uses a microscope to examine the tissue for cancer cells. Like TVU, there is not enough proof that this screening lowers death rates.
If a woman has already suffered from endometrial cancer, a different plan is required to check for recurrence. The screening plans apply to women expected to live for at least ten years. They are not for women with a health condition that makes it hard to diagnose or treat endometrial cancer.
What Are the Risks Associated With Endometrial Cancer Screening Tests?
Screening tests can also have some risks. The risks of endometrial cancer screening include:
-
Screening May Not Help a Woman Live Longer: Finding cancer through screening may not always improve health or increase lifespan. This is especially true if the cancer is already advanced or has spread to other parts of the body.
-
False-Negative Test Results: Sometimes a test may say everything is normal, even when cancer is present. This is called a false-negative result. Because of this, a woman may delay seeking medical care even if she has symptoms.
-
False-Positive Test Results: Sometimes a test may show cancer when there is none. This is called a false-positive result. It can cause worry and stress. It may also lead to unnecessary tests.
-
Side Effects of Screening Tests: Some screening tests may cause discomfort, pain, bleeding, infection, or injury to the uterus.
Conclusion
Endometrial cancer screening is usually done for women at high risk or with symptoms. This is because about 90% of women with endometrial cancer have abnormal vaginal bleeding. Screening works best when it detects early changes in the uterus and improves treatment outcomes. Talk to our female reproductive system specialist for more information about screening.
