💡 Important:
Many of these signs can be caused by less serious conditions (like hemorrhoids, IBS, or infections), but persistent or multiple symptoms should never be ignored. Early detection through screening like colonoscopy dramatically improves outcomes.
If you want, I can make a simple chart showing each warning sign, what it looks like, and what to do—easy to reference. Do you want me to make that?
