Tumor cells
Tumor Cells
Tumor cells (pronunciation: /ˈtjuːmər sɛlz/) are abnormal cells that divide and grow uncontrollably in the body, forming a mass or lump known as a tumor. The term "tumor cell" is derived from the Latin word "tumere", which means "to swell", and the Old English word "cella", meaning "small room".
Tumor cells can originate from any type of cell in the body and can occur in any body part. They are a key component of cancer, a group of diseases characterized by the uncontrolled growth and spread of abnormal cells.
Characteristics
Tumor cells differ from normal cells in several ways. They have abnormal growth and division, lack differentiation, and can invade nearby tissues and spread to other parts of the body (metastasis). They also have the ability to evade the immune system and resist cell death (apoptosis).
Types
There are two main types of tumors: benign and malignant. Benign tumors are not cancerous and do not spread to other parts of the body. Malignant tumors, on the other hand, are cancerous and can invade nearby tissues and spread to other parts of the body.
Causes
The exact cause of tumor cells is not known, but they are thought to be caused by a combination of genetic and environmental factors. Certain oncogenes and tumor suppressor genes are known to play a role in the development of tumor cells.
Treatment
Treatment for tumor cells depends on the type and stage of the tumor, as well as the patient's overall health. Treatment options may include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, or a combination of these.
