Common Oncological Care Procedures
A glossary of common procedures used to screen for, diagnose, stage, treat, monitor, and support people with cancer.
Oncological Care Procedures
Use this glossary to explain common procedures patients, families, caregivers, and healthcare professionals may hear when discussing cancer evaluation, diagnosis, treatment, side effects, supportive care, and follow-up.
Oncological care may include screening, diagnostic testing, biopsies, imaging, surgery, radiation therapy, medication treatment, vascular access, symptom management, rehabilitation, and survivorship care. The procedures used depend on the type and stage of cancer, the person’s overall health, biomarker results, treatment goals, preferences, and available services. Some procedures are performed by the oncology team, while others are coordinated with surgery, radiology, pathology, interventional services, or another specialty.
