Radiology plays a critical role in all stages of cancer management, from initial diagnosis to developing treatment plans, assessing response to therapies, and monitoring for recurrence. Imaging tests like CT scans, PET scans, ultrasounds, and MRIs allow radiologists to detect tumors early, biopsy suspicious areas, map cancer locations, and track changes over time. Radiology provides vital information to oncologists and helps guide important care decisions for patients with cancer.
