Detailed explanation-1: -Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body. Cancer can start almost anywhere in the human body, which is made up of trillions of cells.

Detailed explanation-2: -The American Cancer Society (ACS) defines cancer as a group of diseases characterized by uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death. A cancer cell is a cell that grows out of control.

Detailed explanation-3: -Definition. 00:00. … Cancer is a disease in which some of the body’s cells grow uncontrollably. There are many different types of cancer, and each begins when a single cell acquires a genomic change (or mutation) that allows the cell to divide and multiply unchecked.

Detailed explanation-4: -With increasing cell growth, cancer cells spread or infiltrate to involve other organs, displacing normal tissue and severely depleting nutrient and metabolic resources, which results in death either from cancer cachexia or from mechanical disruption of normal organ function.

Detailed explanation-5: -Gene mutations in cancer cells interfere with the normal instructions in a cell and can cause it to grow out of control or not die when it should. A cancer can continue to grow because cancer cells act differently than normal cells.
