Lynch syndrome


What are the main symptoms of Lynch syndrome?

The main symptom or feature of Lynch syndrome is an increased risk to develop cancer. In general, people with Lynch syndrome have an increased risk to develop colorectal (colon/rectal), uterine (endometrial), ovarian, and stomach cancer. Cancers of the small intestine, urinary tract, brain/central nervous system, liver, biliary tract, and pancreas are also associated with Lynch syndrome. Sebaceous neoplasms, or small growths on the skin, may also be seen with Lynch syndrome. These skins findings can be either benign (non-cancerous) or malignant (cancerous).
