What Is a Full Body PET Scan for Cancer?
A full body PET scan (Positron Emission Tomography) is an advanced imaging technique used to detect cancer and monitor its spread throughout the body. This non-invasive procedure involves injecting a small amount of radioactive glucose into the body, which is absorbed by cancer cells that are more active than normal cells. The PET scanner then captures detailed images of these areas, allowing doctors to identify tumors, measure their size, and assess how far cancer has spread. One of the key advantages of a full body PET scan is its ability to detect cancer in its early stages, even before it is visible on other imaging tests like X-rays or CT scans. It helps doctors to accurately stage cancer, determine the best course of treatment, and evaluate the effectiveness of ongoing treatments like chemotherapy or radiation.
While a PET scan is typically used for patients with suspected or known cancer, it can also be useful for detecting recurrences after treatment. The procedure is generally quick, with minimal discomfort, and provides valuable insights into the presence of cancer or other abnormalities. For individuals diagnosed with cancer or at high risk, a full body PET scan is an essential tool for understanding the disease's progression and ensuring appropriate, timely interventions.
