Every person's cancer is unique.
A growing tumour is made up of many different cancer cells. If a cancer is malignant, a select population of cancer cells can escape the tumour mass and invade the blood stream. When this happens, the cancer is at a turning point. Escapee cancer cells in the blood stream can travel to another site in the body and grow a second tumour at a later stage, called a metastasis. These escapee cancer cells in the blood are called Circulating Tumour Cells, abbreviated as ‘CTCs.’
