Sometimes cell divisioncell division:
The process of one cell splitting into two daughter cells. occurs without being properly regulated. This can be caused by things like smoking, radiation, and any chemical known to be a carcinogen carcinogen:
Any cancer-causing substance..
When cells grow and divide in an uncontrolled fashion, they can form masses of cells called tumors. Tumor cells no longer have a cell cycle that is regulated correctly. They could cause damage to nearby tissues, but they generally stay in one place in the body.

What happens to the rapidly dividing cells when the healing process nearest completion?
The rate of cell division slows down, controls on growth are restored, and everything returns to normal.
Do cancer cells divide?
Yes, cancer cells divide. Uncontrolled cell division is one of the hallmarks of cancer. Normally, cell division is tightly regulated by the cell cycle, a series of steps that ensure cells divide in an orderly manner to replace old or damaged cells and to support growth and development. However, cancer cells lose this regulation and can divide uncontrollably, leading to the formation of tumors. The uncontrolled division of cancer cells can result from various genetic mutations and abnormalities that disrupt the normal regulatory mechanisms of the cell cycle. These mutations can affect genes that control cell growth, cell division, DNA repair, and cell death (apoptosis). Cancer cells may also have the ability to evade signals that normally inhibit cell division, allowing them to continue dividing even when external signals would normally prompt them to stop. Moreover, cancer cells often have the ability to bypass the normal mechanisms that limit the number of times a cell can divide (known as replicative senescence), allowing them to continue dividing indefinitely. The uncontrolled division of cancer cells can lead to the formation of tumors, which can grow and invade surrounding tissues. This unregulated growth and invasion can lead to the spread of cancer to other parts of the body, a process known as metastasis. Understanding the mechanisms of cell division in cancer cells is crucial for developing effective treatments that target the specific vulnerabilities of cancer cells while minimizing harm to normal cells. Many cancer treatments, such as chemotherapy, radiation therapy, and targeted therapy, work by interfering with various aspects of cell division and growth in cancer cells.
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state?
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state stimulate changes to occur in the opposite direction.
Describe a Situation in the human body that would cause an increase in the rate of cell division of certain cells followed by a return to the normal rate of division?
Lets say you get a small injury, like a cut. The skin cells would rapidly divide until the external regulators tell the cell to stop. this will be followed by a return to the normal division rate
What might occur in a leukemia cell that does not occur in a normal cell?
regulation in cell division and growth is stopped
Regulatory function of blood?
maintain normal PH in body tissues.
Describe the body's mechanisms for controlling blood glucose levels under normal and stress conditions.?
Describe the body's mechanisms for controlling blood glucose levels under normal and stress conditions.?
Normal cells become cancer when?
Cells go through a cycle of replication that is normally regulated by a tumor-supressor gene (kind of like a red light for cells). During cancer, that part of the regulatory system is deactivated. What this means is cells can continuously replicated (kind of like a traffic jam).
What happens to the rapidly dividing cells when the healing process nearest completion?
The rate of cell division slows down, controls on growth are restored, and everything returns to normal.
How does cancer happens?
Cells in our body grow, divide, and die in a certain way. Cancer happens when cells either grow, divide, or die wrong or in the wrong way. It ends up being an unpredictable manner that causes uncontrolled growth and division.

Cancer cells do not have the ability to control what?
Cancer cells lose the ability to control their growth and division, which is a fundamental characteristic of cancer. In a healthy organism, cell growth and division are tightly regulated processes, with cells dividing to replace damaged or dying cells and maintaining the overall health of the body. Cancer cells, however, undergo a series of genetic mutations that disrupt the normal regulatory mechanisms, leading to uncontrolled and abnormal cell growth. This loss of control over cell division is one of the defining features of cancer. As a result, cancer cells continue to divide and accumulate, forming tumors and potentially invading nearby tissues and spreading to other parts of the body, a process known as metastasis.
Why should cell division and mitosis should not be used interchangeably?
Not all cell division is mitosis so using the terms interchangeably could be incorrect in some instances.
How have Malignant cells changed?
Malignant cells have changed such that they lose normal control mechanisms governing growth
Which process restores normal cellular function?
cell division
