and 'takes on a life of its own' as it were. This fragment contains the ABL1 gene, connected to another gene. Due to this fusion, ABL1 works non-stop − stimulating cell growth unremittingly. This process leads to an uncontrolled growth of immat...

New method identifies chromosome changes in malignant cells
