Family medical history is one of the first things discussed during a routine doctor’s appointment, but it is often one of the easiest details to overlook. A few questions are asked, a few boxes are checked, and the conversation moves on. For many people, that is perfectly reasonable. For others, those answers may hold important clues about health risks that have existed for generations.
Inherited conditions such as Lynch syndrome are linked to a significantly higher lifetime risk of several cancers. The condition is associated with mutations in DNA repair genes, including the MSH2 gene mutation, and it can pass quietly through families for years before anyone realizes it is there. In many cases, the pattern only becomes obvious after multiple relatives have already faced a cancer diagnosis.
That reality has changed the way many healthcare professionals think about prevention. Rather than waiting for symptoms to appear, hereditary cancer screening offers an opportunity to identify elevated risks earlier and tailor future medical care around that knowledge. Jackie Wenzel’s story shows what that can look like in practice.
Wenzel was diagnosed with uterine cancer at the age of 30, but her family’s history of Lynch syndrome had already raised questions about inherited risk. Even with that knowledge, deciding to undergo genetic testing was difficult, but when she eventually moved forward with testing, the results confirmed that she carried the MSH2 mutation.
Her awareness proved important over the following year as she experienced symptoms including prolonged menstrual cycles, heavy bleeding, and debilitating fatigue. Doctors originally believed she was experiencing hormone-related issues, a common cause of those symptoms. But Wenzel knew that Lynch syndrome placed her at a higher risk for uterine cancer, so rather than accepting the first explanation, she continued seeking additional evaluations until doctors finally discovered she had cancer.
The diagnosis came with difficult decisions, but she also found out early enough to improve her situation. Wenzel wanted to have children, which she managed to do by working closely with her medical team. While she eventually had to undergo a radical hysterectomy, she gave birth to two daughters before then and is now cancer-free.
Her experience is a great example of one of genetic testing’s greatest strengths. It does not guarantee that someone will develop cancer, nor can it prevent every disease, but it can provide information that helps patients and physicians make more informed decisions about screenings, follow-up care, and when symptoms deserve closer attention.
The challenge is that access to hereditary cancer screening has not always been simple. Finding specialists, traveling for appointments, and understanding what type of testing is appropriate can discourage people from taking the next step, even when they know cancer runs in their family.
Lowering those barriers is exactly what jscreen set out to do. The nonprofit has built its work around expanding access to genetic testing and counseling. Through its at-home testing program, individuals can provide a simple saliva sample from home, receive comprehensive genetic analysis through a clinical laboratory, and discuss the results with licensed genetic counselors who help explain what the findings may mean for them and their families.
“A genetic test only helps if people can actually access it,” said Karen Grinzaid, Founding Executive Director of jscreen. “When testing can happen at home and a counselor is there to walk someone through the results, the families who most need that information are no longer left out because the system felt too hard to navigate.”
Not everyone needs genetic testing, but those with a significant family history of hereditary cancers should have a path toward understanding their own risks and discussing them with their healthcare providers.
As conversations around prevention continue to evolve, access may prove just as important as the technology itself. A genetic test only becomes valuable if people are able and willing to take it. For families living with inherited cancer risk, removing those barriers could make the difference between discovering a problem after symptoms appear and understanding the risk before they ever do.
