Cancer Tests Overview

  • Understanding Cancer Tests
  • Cancer Diagnostic Imaging

    Imaging—X-rays, CT scans, MRIs—is a process that produces pictures of body structures and organs. It is used to detect tumors and other abnormalities, to determine the extent of disease, and to evaluate the effectiveness of treatment.

  • Laboratory Tests for Cancer

    Lab tests are used in cancer diagnosis to look for tumor markers. These are substances either released by cancer cells into the blood or urine or substances created by the body in response to cancer cells.

  • Endoscopic Examination for Cancer

    An endoscope is a small, flexible tube with a light and a lens on the end used to look into the esophagus, stomach, duodenum, colon, or rectum. It can also be used to take tissue from the body for testing or to take color photographs of the inside of the body.

  • Biopsy

    Detailed information on biopsy, including the most common types of biopsy such as endoscopic biopsy, bone marrow biopsy, excisional biopsy, incisional biopsy, fine needle aspiration biopsy, punch biopsy, shave biopsy, and skin biopsy

  • Blood Test

    Your doctor might order a blood test to find out if you are sick, if your body is responding to an allergy, or if you are at risk for certain health conditions.

  • Lymphangiogram

    A lymphangiogram is a type of X-ray that is used to look at the lymph nodes and lymph vessels, structures that make up your child's lymphatic system.
