Disseminated disease can refer to disseminatedcancer which is the movement ofcancerous cells from the originaltumor to other areas of the body,[1] or disseminated infection which is thepathogen's entry into the host, growth, and dissemination, which results in illness.[2]
After exiting the maintumor,cancer cells circulate throughout the body. They are known as circulating tumor cells once they are in the blood. Few circulating tumor cells can disseminate to distant locations and remain tumor cells. The amount of disseminated tumor cells that can develop intometastases is even lower.[3]
