Is breast cancer infectious?
No, breast cancer is not infectious. It is a type of cancer that develops in breast cells when they grow uncontrollably. The causes of breast cancer are primarily genetic and environmental factors, not due to any infectious agent.
How are tumor cells different from normal cells?
Cell division is not regulated in tumor cells.
What is the medical term meaning compression of surrounding cells by the 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.
How do maligant tumor cells differ to benige tumor cells?
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.
What are disseminated tumor cells?
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.
