However, with so many diagnostic scans available, how can you tell which one is best for detecting cancer?

The doctor will look at the entire inside of your mouth, and might feel around in it with a gloved finger. CTC scans are generally accurate at detecting cancer and large polyps. Examples of common nuclear scans include the PET scan or the combined PET/CT scan.

For more information, see the PDQ® Breast Cancer Screening summary. Blood tests are sometimes ordered to help doctors diagnose cancer, but different ones are required depending on the type of cancer suspected. Ultrasounds work best on soft tissues, like the breasts, testicles and abdomen. The PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal. BRCA Gene Mutations: Cancer Risk and Genetic Testing, Common Moles, Dysplastic Nevi, and Risk of Melanoma, PDQ® Endometrial Cancer Screening summary, PDQ® Cancer Information Summaries: Screening/Detection (Testing for Cancer), In an Era of Precision Medicine, Testing New Approaches to Breast Cancer Screening, U.S. Department of Health and Human Services, Reduce the chance that someone who is screened regularly will die from the cancer, Have more potential benefits than harms. They prevent the disease because they allow abnormal cells to be found and treated before they become cancer. A CT scan can help doctors find cancer and show things like a tumor’s shape and size. There are three types of CT scan for pancreatic cancer detection. (By comparison, the estimated average annual dose received from natural sources of radiation is about 3 mSv.) For more information, see the PDQ® Ovarian Cancer Screening summary and the PDQ® Endometrial Cancer Screening summary. You are then placed in a tunnel-like device that is able to detect and translate the emitted radiation into three-dimensional images. It's used to help diagnose some conditions including cancer. For more information, see the PDQ® Liver (Hepatocellular) Cancer Screening summary. In our modern-day, there exist several reliable imaging diagnostic systems: X-rays, ultrasound, MRI, CT, and PET scans.

PET stands for positron emission tomography. This imaging test, which can create pictures of a woman’s ovaries and uterus, is sometimes used in women who are at increased risk of ovarian cancer (because they carry a harmful BRCA1 or BRCA2 mutation) or of endometrial cancer (because they have a condition called Lynch syndrome). Ultrasound is one of the few diagnostic scans that does not use radiation, so it is safe for use on pregnant women and children, and others concerned about limiting radiation exposure. Screening tests that have not been shown to be effective may still be offered, especially to people who are known to be at increased risk of cancer. That's because these tests can find abnormal colon growths (polyps) that can be removed before they become cancer. Together, you can decide whether prostate cancer screening is right for you.… For more information, see the Tests to Detect Colorectal Cancer and Polyps fact sheet and the PDQ® Colorectal Cancer Screening summary.

This glucose (FDG) tracer is useful in detecting bone and soft-tissue prostate cancer metastases, although it is less sensitive, therefore not as good as a bone scan for prostate cancer Lastly, FDG tracer are now less favorable in use for prostate cancer compared to others discussed below. The positron emission tomography scan, or PET scan, is the most effective cancer scan in use for detecting and staging cancer. Although this test can help to diagnose ovarian cancer in women who have symptoms and can be used to evaluate the recurrence of cancer in women previously diagnosed with the disease, it has not been shown to be an effective ovarian cancer screening test. Expert groups generally recommend that people who are at average risk for colorectal cancer have screening with one of these tests at ages 50 through 75.
