Hereditary nonpolyposis colorectal cancer (HNPCC) is a hereditary predisposition to colon cancer.. HNPCC includes (and was once synonymous with) [1] Lynch syndrome, an autosomal dominant genetic condition that is associated with a high risk of colon cancer, endometrial cancer (second most common), ovary, stomach, small intestine, hepatobiliary tract, upper urinary tract, brain, and skin. [2]
These were called the Amsterdam II clinical criteria for families with Lynch syndrome. [4] [6] Each of the following criteria must be fulfilled: 3 or more relatives with an associated cancer (colorectal cancer, or cancer of the endometrium, small intestine, ureter or renal pelvis); 2 or more successive generations affected;
The American Cancer Society reported that women under 65 are getting cancer at higher rates. Breast cancer cases are the most common, but female lung cancer diagnoses are also soaring.
Having Lynch syndrome means you're more likely to develop certain cancers before turning 50, ... substantially reduces somebody’s chances of getting colorectal cancer if they have Lynch syndrome ...
Hereditary cancer syndromes underlie 5 to 10% of all cancers and there are over 50 identifiable hereditary forms of cancer. [5] Scientific understanding of cancer susceptibility syndromes is actively expanding: additional syndromes are being found, [6] the underlying biology is becoming clearer, and genetic testing is improving detection, treatment, and prevention of cancer syndromes.

'It felt like all those years of forcing myself to run, eat high-fiber foods, and choke down kombucha were for nothing,' writes Maria Yagoda.
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
Under the name constitutional mismatch repair-deficiency (CMMR-D), it has been mapped to MLH1, MSH2, MSH6 or PMS2. [2] Monoallelic mutations of these genes are observed in the condition known as Lynch syndrome or hereditary nonpolyposis colorectal cancer, while biallelic mutations are observed in CMMR-D. [3] People expressing the HNPCC (which itself is considered autosomal dominant) trait are ...
