Can a CT scan tell if a tumor is cancerous?

A CT scan can identify the size, shape and location of a tumor and provide important clues about whether it may be cancerous. However, a CT scan alone cannot confirm a cancer diagnosis. If a finding looks suspicious, your doctor may recommend a biopsy to collect a tissue sample and determine definitively whether a tumor is cancerous. CT-guided biopsies allow your doctor to pinpoint exactly where the biopsy should be taken.

How small of a tumor can a CT scan detect?

Advanced multi-slice CT technology can detect tumors and nodules just a few millimeters in size. Low-dose CT lung screening, for example, can detect lung nodules as small as a grain of rice. The size of the tumor that can be detected may vary depending on the type of scan, the area of the body being imaged and whether contrast dye is used.

Is a CT scan better than an MRI for cancer?

Both CT scans and MRIs are advanced imaging tools, and each has specific strengths. CT scans are fast, widely available and particularly effective for evaluating solid organs, bones and the chest. MRI provides highly detailed images of soft tissues and is often preferred for brain, spinal cord and musculoskeletal cancers. Your doctor will choose the imaging test that best fits your specific situation, symptoms and the type of cancer being evaluated.

Are CT scans safe for detecting cancer?

CT scans are considered safe and are widely used for cancer detection. One concern some patients have is radiation exposure, but modern CT technology uses a low level of radiation. Your doctor will only recommend CT imaging when the information it provides can help guide care.

What happens after a CT scan shows something unusual?

If a CT scan shows an unusual finding, your doctor will review the results with you and recommend next steps based on what the radiologist found. Depending on the size, appearance and location of the finding, you may need a follow-up CT scan, additional imaging such as a PET-CT or MRI, or a biopsy to gather more information. Finding something on a scan is not automatically a cause for alarm. Your care team will guide you through what the finding means and what to do next.
