====== Tumor ======

A tumor is an abnormal mass of tissue that results from excessive or uncontrolled cell growth. Tumors can be benign (non-cancerous), meaning they do not spread to other parts of the body, or malignant (cancerous), meaning they can invade nearby tissues and potentially metastasize (spread) to distant organs. Tumors can occur in any tissue or organ and vary widely in their behavior, appearance, and clinical impact.
