Several diagnostic tests are used to confirm the presence of cancer:
Imaging Tests: These include X-rays, CT scans, MRI scans, ultrasounds, and PET scans. These tests help visualize the inside of the body and identify abnormal growths. Biopsy: A biopsy involves taking a small sample of tissue for examination under a microscope. This is often the most definitive way to diagnose cancer. Laboratory Tests: Blood, urine, and other body fluids can be tested to detect cancer markers. Endoscopy: This involves using a thin, flexible tube with a camera to examine the internal organs.
