Endometrial Cancer Screening (PDQ®): Screening - Patient Information [NCI] - Risks of Endometrial Cancer Screening
Screening tests have risks.
Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.
The diagnosis of an occult primary tumor is made only if no primary tumor is detected after careful search and does not appear during therapy. Patients with cervical lymph node metastases histologically related to a previously treated primary tumor and patients with lymphomas and adenocarcinoma are excluded. If the biopsy is an undifferentiated carcinoma (in particular, a lymphoepithelioma), the most probable primary site is in Waldeyer ring; for example, the nasopharynx, base of tongue, or tonsil...
The risks of endometrial cancer screening tests include the following:
Finding endometrial cancer may not improve health or help a woman live longer.
Screening may not improve your health or help you live longer if you have advanced endometrial cancer or if it has already spread to other places in your body.
Some cancers never cause symptoms or become life-threatening, but if found by a screening test, the cancer may be treated. It is not known if treatment of these cancers would help you live longer than if no treatment were given, and treatments for cancer may have serious side effects.
False-negative test results can occur.
Screening test results may appear to be normal even though endometrial cancer is present. A woman who receives a false-negative test result (one that shows there is no cancer when there really is) may delay seeking medical care even if she has symptoms.
False-positive test results can occur.
Screening test results may appear to be abnormal even though no cancer is present. A false-positive test result (one that shows there is cancer when there really isn't) can cause anxiety and is usually followed by more tests (such as biopsy), which also have risks.
Side effects may be caused by the test itself.
Side effects that may be caused by screening tests for endometrial cancer include:
Puncture of the uterus (rare).
If you have any questions about your risk for endometrial cancer or the need for screening tests, check with your doctor.
