Answers
Answer:
Cancer is a group of more than 100 different diseases. It can develop almost anywhere in the body.
Explanation:
Cells are the basic units that make up the human body. Cells grow and divide to make new cells as the body needs them. Usually, cells die when they get too old or damaged. Then, new cells take their place.
Cancer begins when genetic changes interfere with this orderly process. Cells start to grow uncontrollably. These cells may form a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A benign tumor means the tumor can grow but will not spread.
Cancer is a board term. It describes the disease that results when cellular changes cause the uncontrolled growth and division of cells. Some types of cancer caused rapid cell growth,while other cause cell to grow and divide at a slower rate. ... cancerous cells may appear in one area, then spread via lymph nodes.
