Step 1

This test uses computer analysis of scanning X-ray images to create cross-sectional pictures. These pictures can portray a tumor's size, location, and X positioning. This technique is particularly useful in detecting and analyzing tumors. Show more…

Key Concepts

Imaging Techniques

Imaging techniques use various technologies such as X-rays, CT scans, MRI, and ultrasound to generate detailed images of the body’s internal structures. These methods help in identifying unusual masses or lesions that could indicate the presence of cancer, and they are often used for initial screening as well as for staging and monitoring treatment progress.

Biomarker Screening

Biomarker screening involves testing for specific molecules, such as proteins, genes, or other indicators in blood or other bodily fluids, that may signal abnormal processes like cancer. These tests can detect changes at the molecular level, providing early warning signs and guiding the need for further diagnostic evaluation.

Tissue Biopsy

A tissue biopsy is a procedure where a small sample of tissue is removed from a suspicious area to be examined under a microscope. This definitive diagnostic test allows pathologists to determine whether cancer cells are present, to identify the specific type of cancer, and to assess its aggressiveness, which is critical for planning appropriate treatment.
