Cell division is not regulated in tumor cells.

Mitosis is not regulated in tumor cells. This can cause the rapid proliferation of a large number of non-functional cells, whose only actions are to divide into more cells.
Tumor cells multiply too quickly.
Tumor cells exhibit uncontrolled growth and division, whereas normal cells follow a controlled growth cycle. Tumor cells may also have the ability to evade the immune system and resist cell death mechanisms that would normally eliminate damaged cells. Furthermore, tumor cells can acquire mutations that allow them to spread to other parts of the body, a process known as metastasis.
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.
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).
Disseminated tumor cells are cancer cells that have detached from the primary tumor and spread through the bloodstream or lymphatic system to other parts of the body. These cells can potentially form new tumors, leading to the progression of cancer in different organs. Detection of disseminated tumor cells in the blood or bone marrow is a negative prognostic factor for cancer patients.
The medical term for compression of surrounding cells by tumor cells is "mass effect." This occurs when a tumor grows and displaces nearby tissues or organs, causing them to become compressed or distorted. It can lead to various symptoms depending on the location and size of the tumor.
Malignant tumor cells are cancerous, tend to grow rapidly, spread to other parts of the body, and can be life-threatening. Benign tumor cells are non-cancerous, grow slowly, do not invade nearby tissues, and are typically not life-threatening.
