Hi, I'm a 27 year old male, and have been having a lot of problems with constant constipation, diarrhea, blood in my stool, cramping, fatigue and nausea, and I'm always tired. I've been to the ER multiple times and they said it was hemorrhoids, but what they prescribe me has never worked. Cancer runs in my family. And I'm just wondering if these symptoms I've been having are cancer related?
