This is because not all cancers are the same, and because some scans work better on certain parts of the body than others. Doctors might use an MRI scan to show: if a lump or abnormal area is cancer or not the size of the cancer and if it has spread. Unlike any other type of cancer scan, the PET scan relies on metabolic differences between malignant and non-malignant cells to detect cancer in the body. To get a full diagnosis, your physician also needs to draw blood or collect tissue for lab tests, and even consult with a specialist. CTC scans are generally accurate at detecting cancer and large polyps. The positron emission tomography scan, or PET scan, is the most effective cancer scan in use for detecting and staging cancer. Whether to test healthy men with no symptoms for prostate cancer is controversial. Examples of x-ray technology include the standard x-ray, computed tomography (CT scans), and mammograms. It's used to help diagnose some conditions including cancer. If an ultrasound detects abnormalities that look like cancer changes in tissues, more tests will be needed to confirm the diagnosis. The biggest difference is that MRIs (magnetic resonance imaging) use … Cancer screening tests aim to find cancer early, before it causes symptoms and when it may be easier to treat successfully. Why you might have a CT scan.

Advanced x-ray machines, like the CT scan or mammogram are good for detecting cancers in softer tissues, like the breasts. This test to screen for lung cancer has been shown to reduce lung cancer deaths... Mammography. 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. Examples of common nuclear scans include the PET scan or the combined PET/CT scan. By detecting radioactive glucose, the PET scan is able to detect which areas of the brain are utilizing glucose at the highest rates. What Are The Best Scans To Detect Cancer? It may be used to see whether pancreatic cancer has spread. This test is sometimes used, along with ultrasound of the liver, to try to detect liver cancer early in people at high risk of the disease. However, expert groups no longer recommend routine PSA testing for most men because many prostate cancers detected with PSA testing are not deadly, and early detection and treatment of PSA-detected cancers has not been shown to reduce the chance of dying from prostate cancer. The MRI uses magnets to detect and diagnose cancers. Promising pancreatic cancer early detection projects are underway, including research funded by Pancreatic Cancer Action Network grants. For more information, see the Pap and HPV Testing fact sheet and the PDQ® Cervical Cancer Screening summary.

Ultrasound. The abnormal cells can also spread to other parts of your body and infect other organs – a process called metastasis. Ultrasound uses sound waves to detect and diagnose cancers.

This blood test, which is often done along with a digital rectal exam, can detect prostate cancer at an early stage. For more information, see the PDQ® Ovarian Cancer Screening summary and the PDQ® Endometrial Cancer Screening summary.
