Final answer:
Uncontrolled cell division often results in cancer, a disease characterized by rapid and unregulated cell growth that can form tumors, causing tissue damage and potentially death.
Step-by-step explanation:
Uncontrolled cell division can result in the formation of cancer. Cancer occurs when the mechanisms that regulate the cell cycle fail, often due to mutations in the genes that control this process. These mutations can arise from inherited genetic abnormalities or from environmental factors such as exposure to radiation or toxic chemicals. As a result of these changes, cells may divide rapidly, forming a mass known as a tumor, which can damage surrounding tissues and potentially lead to death.
