AI overview
A tumor is an abnormal growth of cells in the body that forms a lump or mass. Understanding tumors matters because they can vary widely in how dangerous they are—some are benign (non-cancerous) and harmless, while others are malignant (cancerous) and can spread to other parts of the body, making them a serious health concern.
