Cancer diagnostics refers to the methods and tests used to identify the presence of cancer in the body. This process often begins with a physical examination and a review of medical history. Common diagnostic tools include imaging techniques like X-rays, CT scans, and MRI, as well as laboratory tests such as blood tests and biopsies, where a sample of tissue is examined for cancer cells. Early and accurate cancer diagnostics are crucial for effective treatment. The results help doctors determine the type and stage of cancer, guiding decisions on the best treatment options. Advances in technology, such as genetic testing and liquid biopsies, are improving the ability to detect cancer earlier and more precisely.
