Introduction to Cancer Genetics

Cancer is a group of diseases characterized by uncontrolled growth and spread of mutant body cells.

Mutant body cells in cancer are more metabolically active, depriving normal body cells of nutrients and essential requirements.

Cancer is the second leading cause of death after cardiovascular diseases due to its uncontrolled growth and spread of mutant cells.
