Cancer

Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells. Cells are the building blocks of living things. Cancer grows out of normal cells in the body. Normal cells multiply when your body needs them, and die when the body doesn’t need them. Cancer occurs when the growth of cells in the body is out of control and cells divide too quickly. Depending on the type and location of the tumor, the symptoms will vary. Treatment also varies based on the type of cancer and the stage that it’s in. The stage of cancer refers to how much it has grown and whether the tumor has spread from its original location.
