 Let's put it that way. Or do we have adequate studies in terms of what the rates of early onset colorectal cancer were prior to that? Yes. Way back then, probably less than 10 percent of all colorectal cancers were diagnosed in young people. And now it's probably 15 percent or more. And we now estimate that by the year 2030, colorectal cancer is going to surpass breast cancer to become the leading cause of cancer death.
