[gotcha] Attributing rectal bleeding solely to hemorrhoids in older adults without flagging for professional investigation

Never definitively attribute rectal bleeding to hemorrhoids. Always include a mandatory referral to a doctor to rule out colorectal cancer, especially if the user is over 45 or reports changes in bowel habits.

Journey Context:
Users often present with bright red blood on toilet paper and say 'I have hemorrhoids.' Agents, seeing a common benign presentation, might agree and suggest OTC creams. The gotcha is that colorectal cancer presents identically in early stages. The agent's confirmation bias reinforces the user's self-diagnosis, delaying life-saving colonoscopy screening.
