GENERAL HISTOLOGY

Detailed explanation-1: -Cancer cells are insensitive to the chemical signalling molecules that modulate cell growth and division. This ability to ignore the usual restraints on cellular growth and division apparently occurs as a result of genetic mutation, which alters oncogene or tumour-suppressor gene activity.

Detailed explanation-2: -If you ask an oncologist – a doctor who treats cancer patients – she or he will likely answer with a resounding yes. Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators.
