do gastrointestinal cancer symptoms show up quickly or gradually?

Depends on the type: Gastrointestinal tumors take years to develop, but since they are not located in places you can see (and often, not feel) they can grow quietly without detection. Often, they are not diagnosed until symptoms appear (bleeding, weight loss, changes in bowel function, pain, etc.).
