PATHOLOGY

Detailed explanation-1: -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-2: -Tumors, including cancers, are caused by abnormal cells that multiply continuously. If the abnormal cells continue to divide unstopped, they can damage the tissues around them, spread to other parts of the body (malignancy), and even result in death.

Detailed explanation-3: -Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Detailed explanation-4: -Cancer isn’t a single disease. Cancer is a group of diseases characterized by the uncontrolled proliferation of cells. Ignoring the body’s signal to stop, malignant cells multiply to form tumors in organs and tissues or, in the case of blood cancers, crowd out normal cells in the blood stream and bone marrow.

Detailed explanation-5: -(KAN-ser) A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems.
