Benign prostatic hyperplasia: A common, noncancerous enlargement of the prostate gland.

Benign vs Malignant. The two terms malignant and benign are medical terms and they are often confused with each other. The fact is that they are poles apart in meaning. Malignant means that the affected cells in the body are cancerous. The tumors which are malignant can attack the tissues lying the surrounding region and spread in the body. On the other hand, benign tumor means that the tumor is not cancerous. It might grow in size but it will not spread to other parts of the body.
