What role do imaging tests play in cancer diagnosis?
Imaging tests are crucial in the initial diagnosis, staging, and monitoring of cancer. They help visualize the internal structures of the body. For example, an MRI uses magnetic fields to create detailed images, while a CT scan uses X-rays to produce cross-sectional pictures. These tests can help in identifying the exact location and size of the tumor, as well as whether it has spread to other parts of the body.
