I want to do a whole body cancer cell test, blood can detect it, what is the name big

For systemic cancer cell testing, you can check whether there are malignant tumor cells in the body through blood tests, but if you want to confirm cancer, you need to go through other tests to confirm the diagnosis. The most commonly used for systemic cancer cell testing is PET-CT whole body scan, which is used for early cancer screening. Secondly, it needs to be combined with CT and MRI to check the tumor pathology before it can be /confirm/ied.
