They divide infinitely without slopping. So they increase in size
A benign tumor is an abnormal mass of essentially normal cells that does not spread to other parts of the body.
One key difference is that cancer cells can divide uncontrollably whereas normal cells have a regulated cell division process. This uncontrolled division is one of the factors that leads to tumor formation in cancer cells.
A mass of abnormal cells is a tumor. Sometimes this is cancer and sometimes not.
When cells reproduce out of control, it can lead to the formation of a mass of cells called a tumor. If the tumor is benign, it is not cancerous and typically does not spread to other parts of the body. However, if the tumor is malignant, it is cancerous and can invade nearby tissues or spread to other parts of the body, a process known as metastasis.
Simply: tumor cells tend to be more radiosensitive because they spend more time on average undergoing uncontrolled mitosis than normal cells. Since mitosis is the most sensitive phase of the cell cycle (phase through which the cell is most easily lethally damaged by radiation), their risk is increased. On another note, depending on which genes are causing the cell to become cancerous, certain blockers that would prevent a cell whose DNA had been damaged by radiation might not stop that cell from moving into mitosis, failing, and committing apoptosis (preprogrammed cell death).
Mitosis is not regulated in Tumor Cells -> Apexvs

Cell division is not regulated in tumor cells.
Yes, tumor viruses can contain genes found in normal cells. Some tumor viruses are able to integrate their genetic material into the host cell's genome, which can disrupt normal cellular functions and lead to uncontrolled cell division and tumor formation.
They're different because they grow faster than normal cells and start to kill the cells around them, which can result in a tumor and cause cancer.
Mitosis is not regulated in tumor cells
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
not in all cases, however, but yes
tumor
There is a chance that normal cell that grow in disk can become tumors. This chance is slim.
