The most efficient way to diagnose cancer is to use various diagnostic tests such as X-rays, ultrasounds, CT scans, and MRI scans. Blood tests can also be used to detect certain markers or substances in the body associated with the presence of cancer. In addition, biopsy, which involves taking a sample of the suspicious tissue, is often used to determine whether cancer is present.
