 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 and we can identify those who are at high risk and target that population for earlier screenings.
