WHAT IS CANCER?
Cancer is a group of diseases which arises from a single mutation resulting in uncontrolled cell proliferation and spread (metastasis) to nearby tissue or secondary organs.

When the cells become capable of invading the surrounding tissue, it is called malignant, i.e., cancer. Learn More.
