This prospective observational study will follow adults who are scheduled for a clinically indicated biopsy because of a suspected solid tumor involving bone or soft tissue. The period before biopsy, the disclosure of pathology results, and the start of treatment may be associated with changing levels of psychological stress and anxiety. The purpose of the study is to compare psychological stress and anxiety in the same participants at three points in their care: before biopsy, after the pathology result or diagnosis is explained, and at treatment initiation. The investigators hypothesize that psychological questionnaire scores will differ across these three time points and may be associated with age, sex, disease stage, metastasis status, and treatment type. Participants will complete the Hospital Anxiety and Depression Scale, Perceived Stress Scale, and Distress Thermometer. The study team will also collect relevant demographic and routine clinical information from medical records. The study will not assign any biopsy, diagnostic procedure, or treatment. All diagnostic and treatment decisions will be made by the treating clinical team as part of routine care.
