What can PET scan do?
PET can help doctors locate the presence of cancer/infection anywhere in the body. Because cancers are multiplying and require energy for growth, the PET scan is designed to detect any mass that is growing fast. The PET scan involves the use of radioactive glucose which is injected into the body. The glucose is taken up by the cancer cells and this activity can be monitored by the PET scan. PET scan has the ability to identify tumors in their very early phase. The PET scan can also detect the spread of cancer in other parts of the body.
