Is an intensified nodule a cancer?

Intensified nodules are not necessarily cancer. Intensified nodule is an imaging term that refers to a mass nodule that appears to have increased density after enhancement scan in imaging films such as CT and MRI. The reason for this is that the nodule has a very rich blood supply and a lot of contrast is absorbed through the blood after contrast is injected. Tumor tissues are generally very rich in blood supply, so more contrast agent is absorbed after enhancement scan, thus showing nodal enhancement. However, the enhancement of tumor nodules is generally heterogeneous, usually circular or partial enhancement, which is due to the heterogeneous density of blood vessels inside the tumor tissue. Others, such as inflammatory nodules, will also show different degrees of enhancement after enhancement scans due to higher blood flow supply as well. In addition, hemangioma is a benign tumor, which will show uniform and obvious enhancement after enhancement scan. Therefore, enhanced nodules are not necessarily cancerous, depending on the characteristics of enhancement.
