Neoplasia (literally: new growth) is sudden and abnormal growth in a tissue or organ. Such a growth is called a neoplasm, also known as a tumor. Neoplasia and cancer are often used interchangeably, although technically the latter refers specifically to malignant neoplasia.
The word neoplasm literally means a new growth, from the Greek neo-, new + plasma, that which is formed, or a growth = a new growth.
Cancer - Learn about cancer types, disease statistics, facts, and survival rates, and get information about how malignanttumors (cancerous growths) metastasize or spread.
For example, fibromas are neoplasms of fibrous connective tissue, and melanomas are abnormal growths of pigment (melanin) cells.
In practice it is not always possible to determine the degree of malignancy, and it may be difficult even to determine whether particular tumor tissue is benign or malignant.
