Most cases of Lynch syndrome are due to deficiencies in 1 of 4 DNA repair proteins. Only these 4 proteins are routinely tested by IHC. However, IHC is a screening test, and further genetic tests are needed to confirm a diagnosis of Lynch syndrome.
Not all people who have a tumor which lacks 1 or more of these DNA repair proteins has Lynch syndrome. The changes can also be due to a process called DNA methylation, which typically silences 1 of the more common dMMR genes in the tumor.
Family members may wish to be tested, too. People affected by Lynch syndrome should tell their doctors so they can receive increased screening for Lynch-associated cancers, such as more frequent colonoscopies. Other family members may consider preventive surgery for uterine and ovarian cancers.
If you have uterine cancer, ask your doctor if the cancer can be tested for Lynch syndrome and other possible inherited conditions. Learn more about Lynch syndrome in another section on this website.

Uterine Cancer: Introduction Approved by the Cancer. The uterus has 3 sections: The cervix, which is the narrow lower section The isthmus, which is the broad section in the middle The fundus, which is the dome-shaped top section.
Noncancerous conditions of the uterus include: Fibroids: Benign tumors in the muscle of the uterus Benign polyps: Abnormal growths in the lining of the uterus Endometriosis: A condition in which endometrial tissue, which usually lines the inside of the uterus, is found on the outside of the uterus or other organs Endometrial hyperplasia: A condition in which there is an increased number of cells and glandular structures in the uterine lining.
There are 2 major types of uterine cancer: Adenocarcinoma.

Generally, treatment for people with cancer of the endometrium includes one or more of the following. Pelvic lymph node dissection — removal of some lymph nodes from the pelvis.
Para-aortic lymphadenectomy — removal of lymph nodes that surround the aorta, the main artery of the heart. Laparoscopic lymph node sampling — removal of lymph nodes through a narrow viewing tube called a laparoscope, which is inserted through a small incision cut in the abdomen belly. Sentinel lymph node mapping — use of fluorescent imaging to identify potentially cancerous lymph nodes that would otherwise go undetected. Radiation therapy : the use of X-rays, gamma rays and charged particles to fight cancer.
Brachytherapy and external beam radiation are the most common radiation therapies used to treat endometrial cancer. Novel techniques in image-based brachytherapy with directed magnetic resonance MR guidance offer better patient outcomes and fewer side effects. Chemotherapy : the use of anticancer drugs to treat cancerous cells. Hormone therapy : medication or surgical procedures that interfere with hormone activity. Gynecologic cancers can often be difficult to treat, with traditional therapies — surgery, chemotherapy, radiation — becoming less effective with the recurrence of disease.
Immunotherapy has been showing promise in this area, though, particularly for endometrial cancer. Health Home Conditions and Diseases. What You Need to Know Endometrial cancer starts in the lining of the uterus — the endometrium. What is endometrial cancer?
