Get the Facts: http://genefacts.org Lynch syndrome is a cancer predisposition syndrome caused by inherited mutations in genes responsible for correcting DNA replication errors. Individuals with Lynch syndrome have a greatly increased risk for colorectal, endometrial, and stomach cancers, and a moderately increased risk for other cancers. Key Points 1-3% of colon cancers attributable to Lynch syndrome Dominant inheritance with reduced penetrance (not all patients with mutations will manifest disease) Diagnosis based on clinical and family history, tumor pathology and/or genetic testing Screening and prophylactic surgeries effective in reducing some, but not all cancer risks Mutations in any of several genes can cause the syndrome

Check out this website/blog find!  Great information on Hereditary Colon Cancer and representative of our family's experience with this disease.  It's important to stay informed and stay connected. http://www.ihavelynchsyndrome.com We had our first Tweet Chat on Twitter last night (#LynchsyndromeChat) and almost reached 500,000 people within one hour!

What is Lynch syndrome? Lynch syndrome, often called hereditary nonpolyposis colorectal cancer (HNPCC), is an inherited disorder that increases the risk of many types of cancer, particularly cancers of the colon (large intestine) and rectum, which are collectively referred to as colorectal cancer. People with Lynch syndrome also have an increased risk of cancers of the stomach, small intestine, liver, gallbladder ducts, upper urinary tract, brain, and skin. Additionally, women with this disorder have a high risk of cancer of the ovaries and lining of the uterus (the endometrium). People with Lynch syndrome may occasionally have noncancerous (benign) growths (polyps) in the colon, called colon polyps. In individuals with this disorder, colon polyps occur earlier but not in greater numbers than they do in the general population.

July 10, 2009: Lynch syndrome, often called hereditary nonpolyposis colorectal cancer (HNPCC), is a type of inherited cancer of the digestive tract, particularly the colon (large intestine) and rectum. People with Lynch syndrome have an increased risk of cancers of the stomach, small intestine, liver, gallbladder ducts, upper urinary tract, brain, skin, and prostate. Women with this disorder also have a high risk of cancer of the endometrium (lining of the uterus) and ovaries. Even though the disorder was originally described as not involving noncancerous (benign) growths (polyps) in the colon, people with Lynch syndrome may occasionally have colon polyps. In individuals with this disorder, colon polyps occur at an earlier age than in the general population. Although the polyps do not occur in greater numbers than in the general population, they are more likely to become cancerous.

Reducing the Risk of Colon Cancer Here are some of the preventive steps you and your doctor can take if your genetic test indicates a risk of developing an inherited cancer: Increased Surveillance Colonoscopy every one to two years beginning at age 20-25 or 5-10 years before the earliest age of a diagnosed colorectal cancer in your family, whichever comes first. Colonoscopy annually after age 40. Preventive Surgery If colon cancer (or an advanced precancerous polyp) is diagnosed in a patient with HNPCC , a full, rather than partial, colectomy is recommended. In carefully selected people, for example, those not willing or able to undergo periodic screening, preventive colectomy may be an option based on a positive genetic test result for HNPCC. Preventive Drug Therapies for Colorectal Cancer: Different drugs for the prevention of colorectal cancer are currently being researched for individuals with HNPCC. None of these drugs are currently approved by the FDA for this purpose. Increa...

What's the Genetic Information Nondiscrimination Act (GINA)? The Genetic Information Nondiscrimination Act of 2008, also referred to as GINA, is a new federal law that protects Americans from being treated unfairly because of differences in their DNA that may affect their health. The new law prevents discrimination from health insurers and employers. The President signed the act into federal law on May 21, 2008. The parts of the law relating to health insurers will take effect by May 2009, and those relating to employers will take effect by November 2009. What's genetic discrimination? Genetic discrimination occurs if people are treated unfairly because of differences in their DNA that increase their chances of getting a certain disease. For example, a health insurer might refuse to give coverage to a woman who has a DNA difference that raises her odds of getting breast cancer. Employers also could use DNA information to decide whether to hire or fire workers.
