How are most cancers found?

FAQ

Most cancers are found through a combination of different methods, including:

  1. Screening tests: These are tests that are performed in people who do not have any symptoms of cancer but may be at higher risk due to factors such as age, family history, or exposure to certain carcinogens. Examples of common cancer screening tests include mammograms for breast cancer, colonoscopy for colorectal cancer, Pap test for cervical cancer, and PSA test for prostate cancer.
  2. Diagnostic tests: These are tests that are performed when a person presents with symptoms that may be suggestive of cancer, such as unexplained weight loss, persistent pain, changes in the skin, or abnormal bleeding. Diagnostic tests may include imaging studies such as X-rays, CT scans, MRI scans, or PET scans, as well as biopsies, where a sample of tissue is taken for examination under a microscope to determine if it is cancerous.
  3. Physical examinations: A healthcare provider may perform a physical examination to look for any signs or symptoms of cancer, such as lumps or abnormalities in organs or tissues.
  4. Laboratory tests: Blood tests, urine tests, and other laboratory tests can sometimes detect markers or substances in the body that may indicate the presence of cancer, although these tests are usually used in combination with other methods for a definitive diagnosis.
  5. Imaging studies: Imaging studies such as X-rays, CT scans, MRI scans, or PET scans may be used to visualize internal structures of the body and identify any abnormalities that could be indicative of cancer.

It’s important to note that early detection of cancer greatly increases the chances of successful treatment and outcomes. If you have any concerns about cancer or your risk for cancer, it’s best to consult with a qualified healthcare professional for appropriate screening or diagnostic tests.
