Q. What are neoplasias?
The Neoplasia is any abnormal and uncontrolled proliferation of cells of an organism. The Neoplasias can be benign or malign and benign neoplasias are those in which the cell proliferation is limited to a given site of the body and so neoplastic cells do not spread to other close regions or at distance through the circulation. The Malign neoplasias are those in which the neoplastic cells disseminate at distance to other sites and organs of the body, a process called metastasis, where they continue to proliferate. The Malign neoplasias injure tissues and if not eradicated they are fatal and benign neoplasia can also be deadly when it forms a tumor that grows and compresses vital organs.
