Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms regulating the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.

What is the cause of uncontrolled mitosis?
Overexpression of growth factors or a lack of suppressor proteins can lead to rapid uncontrolled cell division. As cells proliferate without regulation, tumors occur that can become deadly if not treated. Mitosis occurs infinitely.
What is caused by uncontrolled mitosis?
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
What occurs when there is uncontrolled cell division?
Tumors, including cancers, are caused by abnormal cells that multiply continuously. If the abnormal cells continue to divide unstopped, they can damage the tissues around them, spread to other parts of the body (malignancy), and even result in death.
The Cell Cycle (And Cancer) [Updated]
What happens when mitosis is uncontrolled?
Mitosis and Cancer Missense mutations can multiply over time, leading to cell cycle disruption and the formation of tumors , which are the product of runaway cell reproduction. Cancer occurs when mutated cells ignore or override the normal "checkpoints" regulating mitosis and begin to reproduce uncontrollably.
What is an uncontrolled division of cells called?
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
What causes uncontrolled cell division at the genetic level?
Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms regulating the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.
Mutations (Updated)
What occurs during uncontrolled cell division?
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
What is uncontrolled cell growth called?
Cancer is a disease in which some of the body's cells grow uncontrollably. There are many different types of cancer, and each begins when a single cell acquires a genomic change (or mutation) that allows the cell to divide and multiply unchecked.
Genetic Changes That Affect Cell Cycle Control
What is uncontrolled mitosis called?
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators.
What gene causes cell division?
Summary. Two classes of genes, oncogenes and tumor suppressor genes, link cell cycle control to tumor formation and development. Oncogenes in their proto-oncogene state drive the cell cycle forward, allowing cells to proceed from one cell cycle stage to the next.
