Concepts of the neoplasia-tumor and cancer

Question

How dissimilar are the concepts of the neoplasia, tumor and cancer?

Answer 1

Not every tumor is neoplastic and not every neoplasia generates tumor. Tumor is the generic name given to the abnormal raise in volume or mass of any area of body (for illustration, the enlarged tonsils throughout throat infection are a type of tumor, any inflammation creating a swelled area characterize a tumor, and so on).

Neoplasias can form tumors, some of them extremely large, by aggregation of neoplastic cells in region where the neoplasia began or in distant implantations. Cancer is synonym for malign neoplasia.
