That a benging tumor does not metastasize.
Cell division is not regulated in tumor cells.
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.
Tumor cells differ from normal cells primarily in their growth and behavior; they exhibit uncontrolled proliferation, evading the regulatory mechanisms that typically keep cell division in check. Unlike normal cells, which undergo apoptosis (programmed cell death) when damaged or dysfunctional, tumor cells often develop resistance to this process, allowing them to survive and proliferate despite genetic abnormalities. Additionally, tumor cells can invade surrounding tissues and metastasize to distant sites, a characteristic not observed in healthy cells. Furthermore, they may undergo metabolic changes and express different surface markers compared to normal cells.
Tumor cells differ from normal cells primarily in their growth and behavior. They often exhibit uncontrolled proliferation, evading the regulatory mechanisms that typically limit cell division in normal cells. Additionally, tumor cells can undergo genetic mutations, leading to alterations in their metabolism and ability to invade surrounding tissues. Moreover, they frequently acquire resistance to apoptosis, allowing them to survive despite signals that would normally trigger cell death.
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.
they do not. In fact, a maligant tumor goes through uncontrolled mitosis, and does not stop reproducing.
They divide infinitely without slopping. So they increase in size
Mitosis is not regulated in tumor cells
Cell division is not regulated in tumor cells.
An osteoblastoma is a tumor of immature bone cells.

Some can, not all. If the tumor contains cells that can it will metastasize.
Metastasis
It is called as malignant tumor.
A mass of diseased cells is a tumor.
A lipoma is a benign tumor of fat cells.
