Cancer diagnosis involves a series of tests and evaluations to determine the presence of cancer in the body. Common methods include imaging tests like X-rays, CT scans, and MRIs, as well as laboratory tests such as blood tests and biopsies. A biopsy involves taking a small sample of tissue to examine it for cancer cells. Once the tests are completed, a healthcare professional, often an oncologist, reviews the results to confirm whether cancer is present and to identify its type and stage. This information is crucial for developing an effective treatment plan tailored to the patient's specific needs.
