I recently read a press- release that very attractively used the term fly-paper to describe a novel invention by researchers at UCLA that can be used to grab maverick cancer cells circulating in the blood stream. These ‘mavericks’ I might add are known in Cancer jargon as Circulating Tumour Cells or CTCs. These tumour cells escape from an already formed tumour in the body and begin to circulate in the body via the bloodstream that involuntarily acts as a transport medium for these dangerous cells. The CTCs now form newer tumours in locations distinct from that of the original tumour, resulting in formation of ‘satellite tumours’ or colonies of tumour cells, giving rise to one of the most Distinctive and scaring features of a malignant tumour, namely, Metastasis.
