Tumorigenesis

Tumorigenesis is the process by which normal cells transform into cancerous cells, leading to the formation of tumors. This transformation can occur due to genetic mutations, which may be triggered by factors such as exposure to carcinogens (like tobacco smoke), radiation, or certain viruses. As these mutated cells grow uncontrollably, they can invade nearby tissues and spread to other parts of the body. Understanding tumorigenesis helps in developing targeted treatments and preventive measures against cancer.
