A white blood cell formed in the thymus that attacks cancer cells is a type of T lymphocyte known as a cytotoxic T cell. These cells recognize and destroy abnormal cells, including cancer cells, to help protect the body from disease and infection.
Cancer is classified as an abnormal growth of cells. This may happen because of a mutation in the cells DNA. When the cells grow abnormal, it usually grows too fast.
pre cancer cells are cells with an abnormal appearance suggestive of an increased cancer risk. These cells are not cancerous by themselves alone.
Cancer is the disorder characterized by abnormal replication of cells that can lead to the formation of tumors.
The abnormal development or growth of cells is called tumor or neoplasm, which can be benign or malignant. In the case of cancer, the cells divide uncontrollably and can invade surrounding tissues.
a mass of abnormal cells
Atypical cells are cells that appear to be abnormal and need further testing to determine why they are abnormal. Sometimes these cells can end up being cancer but not all atypical cells will.
Cells of the immune system, particularly certain types of white blood cells, primarily target cancer cells. The main types of immune cells involved in targeting cancer cells include: Cytotoxic T Cells (CD8+ T Cells): These cells directly attack and destroy cancer cells by recognizing specific antigens present on the surface of the cancer cells. Natural Killer (NK) Cells: NK cells are a type of lymphocyte that can recognize and kill abnormal cells, including cancer cells, without prior sensitization or the need for specific antigens. Macrophages: Macrophages are immune cells that engulf and digest foreign substances, including cancer cells, through a process called phagocytosis. They also play a role in presenting antigens to other immune cells to initiate an immune response against cancer. Dendritic Cells: Dendritic cells are antigen-presenting cells that capture antigens from cancer cells and present them to T cells, thereby activating an adaptive immune response against the cancer. Tumor-Infiltrating Lymphocytes (TILs): These are lymphocytes that have migrated into the tumor microenvironment and are involved in recognizing and attacking cancer cells. Cytokine-Induced Killer (CIK) Cells: CIK cells are a type of immune cell that has been activated and expanded outside the body and then reintroduced into the patient to target and kill cancer cells. These immune cells, along with other components of the immune system, form a complex network known as the immune response, which plays a crucial role in recognizing and eliminating cancer cells from the body.
The disease characterized by the unrestrained growth of abnormal cells in or on tissues of the body is known as cancer.
Killer cells, specifically cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells, play a crucial role in the immune system's defense against cancer. They recognize and bind to cancer cells that display abnormal antigens or stress signals, leading to the release of cytotoxic molecules that induce apoptosis, or programmed cell death, in the targeted cancer cells. This process is essential for controlling tumor growth and preventing metastasis. Additionally, the effectiveness of killer cells can be enhanced by immunotherapy, which aims to boost their activity against cancer.
i think it is Alzheimer's disease. that's what it said on GoogleCancer is abnormal cell division.
