Neoplasm is an abnormal growth of tissue, which if it forms a mass, is commonly referred to as a tumor. This abnormal growth (neoplasia) usually but not always forms a mass.

A tumor does not mean cancer-tumors can be benign (not cancerous), pre-malignant (pre-cancerous), or malignant (cancerous).There are many different types of tumors and a variety of names for them-their names usually reflect their shape and the kind of tissue they appear in.enign means it is non-progressive, it remains as it is. Most benign tumors are not harmful to human health. Even though they are not cancerous, some may press against nerves or blood vessels and cause pain or other negative effects.
