What are X-rays and How are They Used in Cancer Diagnosis?
X-rays are a form of electromagnetic radiation that can pass through the body, producing images of internal structures. They are particularly effective for detecting abnormalities in bones and certain soft tissues. In cancer care, X-rays are often the first step in identifying suspicious areas that may require further investigation. For example, a chest X-ray is a common test to look for lung cancer or metastases from other cancers. X-rays can also be used to check for bone metastases in cancers such as breast or prostate cancer. However, X-rays have limited ability to differentiate between benign and malignant tissues, which is why additional imaging may be required.
