Cell fusion is a process in which a number of cells combine to form a new cell with more than one nucleus. Cell fusion has been postulated just as one cause for some cancers since it could describe the occurrence of multiple genetic adjustments considered to underlie cancer. However, direct evidence that fusion of normal cells alone could trigger cancer has not been reported. Now, a new study published in The American Journal of Pathology supplies the missing link between a single untoward event, cell fusion, and the multiple catastrophic genetic changes that eventually transform normal cells into cancerous cells.
