Why and/or how disruptions to the cell cycle can lead to cancer?

What do disruptions in the cell cycle lead to?

Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor .

What phase of the cell cycle causes cancer?

DNA Synthesis (S phase)

In many cancer cells the number of chromosomes is altered so that there are either too many or too few chromosomes in the cells. These cells are said to be aneuploid. Errors may occur during the DNA replication resulting in mutations and possibly the development of cancer.

What do cells do to cause cancer?

Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide.

Which is the shortest phase?

Note: The shortest phase of the cell cycle is the Mitotic phase (M phase) and the longest phase of the cell cycle is G-1 phase.
