The efficacy of surveillance has only been proven for CRC; however, specialists have proposed surveillance for other LS associated tumors. or. Lynch syndrome is due to inherited changes (mutations) in genes that affect DNA mismatch repair, a process that fixes mistakes made when DNA is copied. Though we have not identified genetic causes for all types of cancer, we do know several gene changes, or mutatations, that can be passed down from parent to child and increase a person's risk of developing the disease. Lynch syndrome families may also include individuals with other gastrointestinal, gynecologic, and genitourinary cancers, or other extracolonic cancers.

When the MMR genes were identified as the underlying genetic etiology of Lynch syndrome in the early 1990s, little was known about the optimal means of diagnosis of families with Lynch syndrome or prevention of Lynch-associated cancers, and the malignancies that developed were treated in exactly the same way as their sporadic counterparts. an ongoing registry, which we will continue to study for an indefinite period of time, since new genes and risk factors may be identified in the coming years. In Lynch Syndrome (LS), the abnormality is a mutation of the deoxyribonucleic acid (DNA) repair system.

This is a survey study to describe how women with Lynch syndrome are being screened for gynecologic cancer risk, their perception of cancer risk, and uptake of risk reducing surgery. Lynch syndrome is the most common cause of inherited colorectal cancer (CRC). Lynch Syndrome is an autosomal dominant disorder that involves a germline mutation to a DNA mismatch repair (MMR) gene (MLH1, MSH1, MSH6 or PMS2). Researchers have identified the majority (94%) of MSH2 variants that could cause Lynch syndrome, a type of inherited cancer. l hese guidelines t are summarized in ablet 1, and the reader is encouraged to refer to them directly for supplementary content.
