Cancer
Proteins called internal regulators and external regulators control the cell cycle. Internal regulatory proteins allow the cell cycle to proceed only when certain events have occurred in the cell itself. External regulatory proteins direct cells to speed up or slow down the cell cycle.
That is incorrect. Cancer can result when cells lose control over the cell cycle and continue to divide uncontrollably. This uncontrolled cell division can lead to the formation of tumors.
Key checkpoints in the cell cycle that control whether the cell will divide include the G1/S checkpoint, which assesses DNA damage and cell size before entering DNA synthesis phase, and the G2/M checkpoint, which checks for DNA replication and repairs before entering mitosis. Additionally, the cell relies on checkpoints during metaphase to ensure proper attachment of chromosomes to the mitotic spindle.
Cells must divide correctly to maintain tissue structure and function. Mistakes in cell division can lead to genetic mutations, DNA damage, and cell dysfunction, which can in turn cause diseases such as cancer. Proper cell division also ensures that new cells are produced to replace old or damaged cells, allowing for growth and tissue repair.
The cell control center, or nucleus, is typically located in the center of the cell. The cell membrane, which surrounds the cell and controls the entry and exit of substances, is located on the outer boundary of the cell.

The ability to stop mitosis. Cancer is cells that continually divide.
Loss of cell cycle control is typically an oncogenic process. For cancer to occur, the cells need to replicate beyond any normal physiological control. To answer your question, one factor that in important in controlling the cell cycle is p53. p53 is a checkpoint control in the G1 phase of the cell cycle. Defects in p53 cause a loss of cell cycle regulation and are considered an oncogenic transformation.

The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
