 Right. You know, I had a friend that just had this done within the last month and he went in for a regular exam and they did the test and found out that he is actually at stage 3 cancer. So he had no symptoms for a long time and they caught it and he told me the other day that he thought his prognosis was going to be really good. So it's important to get that screening done. And colorectal cancer, the same type situation?
