Detecting cancer at an early stage can improve the chances of receiving timely treatment and achieving better outcomes. A CT scan, also called computed tomography or a CAT scan, is an advanced imaging test that provides doctors with detailed, three-dimensional views of the inside of the body. CT scans have many medical uses, including identifying internal bleeding or blood clots, bone fractures, and injuries involving the spine or brain. They are also an important tool for detecting and evaluating cancer. So, how can a CT scan help identify cancer?
Detecting Tumors Without an Invasive Procedure
A CT scan is a painless imaging procedure that allows doctors to examine possible tumors without making an incision or performing an invasive procedure.
- Southwest Diagnostic Center for Molecular Imaging can identify a cancerous tumor because CT imaging provides detailed information about its size, shape, location, and overall mass. It may also show blood vessels supplying the tumor.
- CT scans are commonly used during cancer staging to help determine how advanced the cancer is and whether it has spread to nearby lymph nodes or other organs.
- CT imaging can help doctors look for signs that cancer has returned after treatment.
- CT scans may also help determine whether a specific cancer treatment is working effectively.
In some cases, a contrast agent may be used to make certain tissues or areas of concern easier to see. Together, these details can help doctors develop an appropriate treatment plan.
Which Cancers Can CT Scans Detect?
One of the cancers frequently evaluated with CT imaging is lung cancer. People over age 50 who have a history of heavy smoking may be advised to undergo annual low-dose CT screening to help identify lung cancer at an earlier stage.
CT scans are also commonly used when evaluating cancers in the abdomen, including:
- Bladder cancer
- Pancreatic cancer
- Kidney cancer
- Ovarian cancer
- Stomach cancer
Additional Testing May Be Used Alongside CT Scans
Depending on the situation, your doctor may recommend other tests in addition to a CT scan. For example, an ultrasound or MRI may be used to provide additional information when evaluating certain cancers, including those involving the brain.
CT scans, along with blood tests, physical examinations, and biopsies, can give your healthcare team a more complete picture of your health and help guide diagnosis and treatment.
