cancerous
Step-by-step explanation:
Cancer can be defined as the uncontrolled division of certain body cells, which then invade the surronding tissues and interfere with the normal functioning of the body. It is caused by exposure to extremely dangerous radioactive substances such as gamma ray, uranium etc.
Some examples of cancer are breast cancer, prostrate cancer, carcinoma, etc.
A tumor can be defined as an abnormal mass of tissue formed when various body cells grow and divide more than its required or fail to when necessary (required). Thus, it usually degenerate into cancerous growths (cancer).
