One-Page Truth-Telling Aid for Cancer Disclosure

The goal of this clinical trial is to learn whether a one-page communication aid can improve communication between physicians and patients with cancer during cancer-related truth-telling consultations. The one-page aid is designed to help physicians quickly understand patients' preferences and needs before the consultation. The main questions it aims to answer are: * Does the one-page communication aid improve patients' satisfaction with how cancer-related information is explained? * Does the one-page communication aid reduce patients' emotional distress after the consultation? * Does the one-page communication aid improve physicians' confidence in communicating cancer-related information? Researchers will compare patients whose physicians receive the one-page communication aid with patients whose physicians provide usual care with a blank sheet for patients to write down questions. This comparison will help determine whether the one-page aid improves communication, emotional outcomes, and physician confidence. Participants will: * Complete questionnaires before and after the consultation * Receive either the one-page communication aid or a blank sheet, depending on their physician's group * Complete follow-up questionnaires at 3 months and 6 months after the consultation Physicians will also complete brief questionnaires about their communication confidence at baseline, 1 week after recruitment of their first enrolled patient, 3 months, and 6 months.
