The Cancer Definition Cancer is a condition in which some cells in the body grow out of control and spread to other regions of the body. Cancer may begin practically anywhere in the billions of cells that make up the human body. Human cells normally expand and multiply (via a process known as cell division) to generate new cells as needed by the body. Cells die as they get old or injured, and new cells replace them. This ordered process can sometimes break down, resulting in aberrant or damaged cells growing and multiplying when they shouldn't. Tumors, which are masses of tissue, can grow from these cells. Tumors may or may not be malignant (benign). Cancerous tumours can infect adjacent tissues and spread to other parts of the body, resulting in the formation of new tumours (a process called metastasis). Malignant tumours are another name for cancerous tumours. Many malignancies, including leukemias, create solid tumours, whereas cancers of the blood do not. Benign tumours do not
The body is composed of very small cells . Body cells grow , die and controlled manner . However, the cells continue to divide and grow uncontrolled sometimes , causing the appearance of abnormal growth called a tumor. If the tumor has not moved to nearby tissues and other organs of the body , called a tumor is benign or non-cancerous . Benign tumors do not cause death often . Begins to cancer , such as colon cancer , such as increased growth in normal cells normally , and called Bouliba or polyp . The cells continue to grow in the polyp uncontrolled and without control . If you have not been discovered , it has become cancerous . The more polyps were detected early and eradicated , the greater the chances of avoiding cancer and his recovery success . If the tumor has spread to nearby tissues and cells are destroyed , called a malignant tumor or cancer . Cancer is a deadly disease . Cancer cells may spread to other parts of the body through the blood vess
