Final answer:
Cancer is characterized by non-differentiated cells that exhibit loss of contact inhibition, uncontrolled growth, and the ability to invade tissues and metastasize.
Step-by-step explanation:
Cancer is characterized by non differentiated cells that exhibit loss of contact inhibition, uncontrolled growth, and the ability to invade tissues and metastasize. Cancer is a disease in which some of the body's cells grow and multiply uncontrolled. The uncontrolled division and growth of cells appear as a tumor, which can be benign if it remains limited in growth without harming the neighboring tissues, or malignant if it invades other tissues and interferes with their normal functions.
