Lynch syndrome is a genetic condition that increases the risk of developing certain types of cancer, particularly colorectal cancer and endometrial cancer. It is caused by inherited mutations in specific genes responsible for repairing DNA. People with Lynch syndrome may develop these cancers at a younger age than the general population, making regular screenings and preventive measures essential. Individuals with Lynch syndrome also have a higher risk of other cancers, such as ovarian cancer and stomach cancer. Genetic testing can help identify those at risk, allowing for early detection and better management of potential health issues.
