process of normal cells transforming into cancerous tumors
Tumorigenesis, also known as tumor formation, is the process by which normal cells transform into cancer cells and begin to grow uncontrollably, forming a mass or tumor. This process involves a series of genetic mutations and changes in cellular behavior that allow the cells to evade normal growth controls, resist cell death, and often gain the ability to invade surrounding tissues and spread to other parts of the body.
