Doctor can examine: High school students almost never have bowel cancer. A person cannot tell if he is the rare unlucky one to get cancer at a young age, but more importantly, a person absolutely cannot live his life worrying about rare diseases. The best one can do is live a healthy life, see the doctor for evaluation. That means start with a full exam by one's primary care doctor, but can try a video visit first.
