Benign neoplasms are non-cancerous growths that arise from the abnormal proliferation of cells. Unlike malignant tumors, they do not invade surrounding tissues or spread to other parts of the body. Common examples include lipomas, which are fatty tumors, and adenomas, which develop from glandular tissue. These growths can occur in various organs and may vary in size. While benign neoplasms are generally not life-threatening, they can cause problems if they press on nearby structures or organs. Treatment may involve monitoring or surgical removal, depending on their size and location.
