How do we check for cancer?

As an expert in the field of medical diagnostics, I can provide you with information on how cancer is typically detected. It's important to note that cancer detection can involve a variety of methods, and the approach often depends on the type of cancer suspected, the patient's symptoms, and their medical history. Blood tests are one way to detect cancer, particularly for blood cancers like leukemia or lymphoma. A Complete Blood Count (CBC) is a common test that measures the levels of different types of blood cells. Abnormalities in the number of cells or the presence of abnormal cells can be indicative of cancer. Other diagnostic methods include: 1. Imaging tests like X-rays, CT scans, MRIs, and PET scans, which can reveal abnormalities in organs and tissues. 2. Biopsy, where a small sample of tissue is taken and examined under a microscope for cancerous cells. 3. Endoscopic exams, which use a thin, flexible tube with a light and camera to view the inside of certain organs. 4. Physical exams and self-examinations, where doctors or patients can sometimes detect lumps or other changes that may be signs of cancer. 5. Molecular and genetic testing, which can identify specific genetic mutations associated with certain types of cancer. It's crucial to remember that not all lumps or abnormalities detected are cancerous, and further testing is often required for a definitive diagnosis.

Examples of blood tests used to diagnose cancer include: Complete blood count (CBC). This common blood test measures the amount of various types of blood cells in a sample of your blood. Blood cancers may be detected using this test if too many or too few of a type of blood cell or abnormal cells are found.
