    en.wikipedia.org/wiki/Circulating_Tumor_Cell

    A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1] CTCs are carried around the body to other organs where they may leave the circulation and become the seeds for the subsequent growth of secondary tumors .

    Tumor stroma and extracellular matrix in hypoxia.

    Carcinocythemia, also known as carcinoma cell leukemia, [2] is a condition in which cells from malignant tumours of non-hematopoietic origin are visible on the peripheral blood smear. [ 3 ] [ 4 ] It is an extremely rare condition, [ 5 ] with 33 cases identified in the literature from 1960 to 2018. [ 4 ]
