Natural Killer Cells lack the membrane molecules that identify B and T cells, but they have the ability to kill a wide variety of infected body cells and certain tumor cells.
Natural killer (NK) cells are nonspecific lymphocytes that play a crucial role in killing tumor cells and virus-infected cells. They are part of the innate immune system and can quickly identify and destroy abnormal cells without the need for prior exposure.
The cells mainly used to kill infectious microbes and tumor cells are immune cells called cytotoxic T cells and natural killer cells. These cells can recognize infected or abnormal cells and destroy them by releasing toxic chemicals or by inducing programmed cell death.
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.
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.

it kills tumor cells by breaking them apart
Radiation therapy kills malignant tumor cells by breaking them apart.
Natural killer cells are a type of lymphocyte that can directly kill infected cells and tumor cells. They promote the immune response by releasing chemicals that attract other immune cells to the site of infection. By targeting and destroying infected cells, natural killer cells help the body eliminate pathogens and limit the spread of infection.

Mitosis is not regulated in tumor cells
Cell division is not regulated in tumor cells.
An osteoblastoma is a tumor of immature bone 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.
The radiation kills cells (healthy & neoplastic alike). IF you can kill the tumor cells without destroying too much health tissue, THEN you can claim that it's a treatment.
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.
In any cancer tumor, there are what's called 'cancer stem cells'. These cancer stem cells behave like stem cells in that they are usually quiescent but when the tumor is destroyed by for example radiation therapy and chemotherapy, which targets dividing cells, the tumor stem cells can survive these treatments and begin to divide and recreate the tumor after the treatment has ceased. Right now there are no effective treatment except for surgery that can selectively target cancer stem cells and this is the cause of high recurrence rates in certain cancers. There are also studies that show that directly injecting neural stem cells into brains with neural tumors can directly reduce the size of the tumor without harming surrounding cells. This makes stem cells sound like the 'silver bullet' for neural tumors however much more research needs to be done before this effect can be understood enough for human usage or usage for other organs.
