उत्तर
Cancer is an abnormal and uncontrolled division of cells that invade and destroy the surrounding tissue, forming a tumour or neoplasm. It is a heterogeneous group of cells, that do not respond to the normal cell division. The cancer cells move to distant parts of bodies such as lungs, bones, liver, skin and brain.
