Managing Lynch Syndrome . Screening tests are tests that are designed to detect cancer prior to the presence of any symptoms. Screening for cancer helps ensure that cancer is detected in its earliest stages when it is most treatable. The National Comprehensive Cancer Network (NCCN) provides a set of screening guidelines for individuals with Lynch syndrome.

Individuals with Lynch syndrome tend to develop polyps that are more difficult to detect, which may require the use of newer colonoscopy techniques, such as chromoendoscopy, which uses dye to color colon tissue and help detect flat polyps. Sigmoidoscopy is not recommended for individuals with Lynch syndrome as it only examines a small portion of the colon and does not look at the other portions of the colon which are at risk for developing cancer as well.
Signs and symptoms of colon cancer. Bleeding from the rectum. Blood in the stool or toilet after a bowel movement. A change in the shape of the stool (i. During an endometrial biopsy, a physician removes a small piece of tissue from the uterus to examine it for changes that may indicate cancer.
Some women with Lynch syndrome, particularly those with a family history of uterine cancer, choose to undergo an annual endometrial biopsy during their annual pelvic exam. Screening or not, abnormal uterine bleeding is always cause for further evaluation. Women with Lynch syndrome who experience bleeding (other than a menstrual period) should see a physician.

Pain on urination. Pain on sexual intercourse. Blood in the stool or urine. Ovarian Cancer: Because ovarian cancers begin deep in the pelvis, they often do not cause any symptoms until they are at an advanced stage. Ovarian cancer is difficult to detect through screening tests.
In the general population, screening for ovarian cancer has not been shown to reduce the risk of death. However, because women with Lynch syndrome have an increased risk of developing ovarian cancer, some clinicians believe that screening is warranted in this population. The NCCN has determined that screening may be considered at the clinician. There are two types of screening tests that can be used for ovarian cancer and neither has been shown to be sufficiently sensitive or specific: Transvaginal ultrasound: A transvaginal ultrasound is an imaging procedure during which a physician inserts a probe into the vagina to examine the reproductive organs and bladder. CA- 1. 25: CA- 1. The serum CA- 1. 25 test is a blood test that looks for high levels of CA- 1. The test is imperfect and is not considered a reliable method for detecting ovarian cancer.
Some physicians choose to use both transvaginal ultrasound and the serum CA- 1. Lynch syndrome. Signs and symptoms of ovarian cancer. The symptoms that are more likely seen in women with ovarian cancer than healthy women include: Bloating.
Pelvic or abdominal pain. Difficulty eating or feeling full quickly. Urinary symptoms (urgency or frequency)Transvaginal Ultrasound. Other Cancers: Screening recommendations for the less common Lynch- associated cancers vary based on family history. Urinary Tract: If your family has a history of cancers associated with the urinary tract, your doctor may recommend periodic screening for these cancers. Sometimes an annual urine analysis is recommended; however, there is no proven benefit to this screening test. The NCCN suggests considering annual urinalysis beginning at age 2.
Gastrointestinal Cancer: According to the NCCN guidelines, there is no clear evidence to support screening for gastric or small bowel cancer in individuals with Lynch syndrome. If your family has a history of stomach cancer or cancer of the small intestine, your doctor may recommend annual endoscopy screening for these cancers beginning at age 3. Skin Cancer: Lynch syndrome is associated with an increase risk of sebaceous skin cancer (which affects the sweat glands). Some people opt to undergo risk- reducing surgery in order to prevent cancer.
Some surgical options for preventing cancer include: Hysterectomy: A hysterectomy refers to surgical removal of the uterus. Removing the uterus eliminates the possibility of developing uterine cancer in the future; however, it also eliminates the possibility of pregnancy. Many women with Lynch syndrome opt to undergo hysterectomy once they are done having children and are approaching menopause.
Oophorectomy: An oophorectomy is a surgical procedure to remove the ovaries, which reduces the risk of ovarian cancer. Once done having children, many women with Lynch syndrome choose to undergo hysterectomy and oophorectomy (removal of the uterus, ovaries, and fallopian tubes) in order to reduce their risk of cancer. Colectomy. This is a drastic measure that is generally only considered when someone is unable to undergo regular screening colonoscopy, as there is little evidence that a colectomy has any advantage. Because Lynch syndrome increases the risk of certain types of cancer, preventive strategies are of the utmost importance. While you may not be able to completely eliminate the risk of developing cancer, there are steps that you can take to reduce the risk. Aspirin. The results of the CAPP2 trial (Cancer/Adenoma Prevention Program) indicate that a minimum of two years of 6. Lynch syndrome by about 6.

There are some side effects associated with regular aspirin use, including gastrointestinal ulcers and bleeding. There is also a small risk of developing cerebral hemorrhage (uncontrolled bleeding in the brain). If you are interested in using aspirin to reduce your risk of developing cancer, discuss the risks and benefits of daily aspirin with your physician. Oral Contraceptives. We recommend that you talk to your gynecologist about.
Lifestyle modifications. Several studies have indicated that a healthy diet and exercise may reduce the risk of developing cancer. Eating a diet rich in fruits, vegetables, and whole grains provides a number of health benefits, as does undergoing regular physical activity. Discussion should include known risks, limitations, and benefits of these technologies.
