How is nonpolyposis colorectal cancer discovered if there are no polyps to detect during sigmoi/colonoscopy?
I’m trying to understand what the early symptoms of this form of colorectal cancer are and how they differ from classic adenomatous CRC. If you are qualified to answer this question, I appreciate your answer and thank you in advance.

This is a rare hereditary cancer so you would be genetically tested. There are no early symptoms and you should never wait for symptoms. It is recommended that screening start 5years before the age of the youngest family member at diagnosis.
