Tumors are abnormal growths of cells that can develop in any part of the body. They can be benign (non-cancerous) or malignant (cancerous). Benign tumors typically grow slowly and do not spread to other tissues, often remaining localized and sometimes causing issues by pressing on nearby organs or structures. Malignant tumors, on the other hand, have the ability to invade nearby tissues and spread to distant parts of the body through a process called metastasis. The treatment and prognosis for tumors vary greatly depending on their type, location, and whether they are benign or malignant. Early detection and appropriate medical intervention are crucial for effective management.
