tumor

A tumor is an abnormal mass of tissue formed by the uncontrolled growth of cells in the body. Tumors can be classified as benign (non-cancerous) or malignant (cancerous). Benign tumors usually don’t spread and are often not harmful, while malignant tumors can invade nearby tissues and may spread to other parts of the body. Tumors can develop in various organs and are often detected through symptoms, imaging tests, or biopsies. Understanding tumors is important for diagnosis and treatment, as different types require different approaches to manage them effectively.
