Benign tumor or cyst: This is the most straightforward answer to the question, as the term "benign" directly refers to non-cancerous growths or conditions that do not invade surrounding tissues or spread to other parts of the body.

Hyperplasia: A condition where there is an increase in the number of cells in an organ or tissue, which can be a response to injury or disease but is not cancerous.
Hemangioma: A common, benign vascular tumor made up of blood vessels that can appear early in life and often regress on their own.
Lipoma: A benign tumor composed of fat tissue, which is usually soft, movable, and painless.

Early stage cancer: Although the question asks about benign conditions, it's crucial not to miss early signs of cancer, which can sometimes present with benign-like symptoms or appear as benign growths initially.
Lymphoma (if applicable to the context): Certain types of lymphoma can present with benign-appearing lymph node enlargements or masses.
Phyllodes tumor (in the context of breast lesions): While mostly benign, a small percentage of phyllodes tumors can be malignant, making accurate diagnosis critical.

Hamartoma: A rare, benign growth that can occur in various parts of the body, composed of an abnormal mixture of cells and tissues normally found in the area of the body where the growth occurs.
Teratoma (mature): A rare type of benign tumor that can contain several different types of tissues, such as hair, muscle, and bone, usually found in the ovaries or testes but can occur in other locations.
Neurofibroma: A rare, benign tumor of the peripheral nerve sheath, often associated with neurofibromatosis type 1 (NF1), a genetic disorder.
