 This is why it's important to actually ask your family about your family history, because if there is, for example, a first-degree relative who has had colorectal cancer or an advanced polyp at a young age, you may be eligible to get screening earlier, and then insurance companies may cover that. But for the vast majority of the 20-year-olds and 30-year-olds, this is why we need more research about the causes of underlying young-onset cancer. If we know the causes, then we can identify those who are at high risk and target that population for earlier screenings.
