Cancer Types And The Cells They Originate From

Myeloma

When cancer originates in an individual's plasma cells, which are responsible for the production of infection-fighting antibodies, it is referred to as myeloma. Myeloma forms in specific plasma cells called plasma B cells when they are inside an individual's bone marrow. Myelomas are a type of plasma cell dyscrasia that can be classified into one of several forms. Multiple myelomas are the variation where numerous areas around the patient's body are affected and are the most common form of myeloma. Plasmacytoma is the form of myeloma characterized by a single focal site of myeloma cells in the body. Plasmacytoma often manifests as a tumor in a patient's skin, lung, bone, or muscle. Localized myeloma is a form similar to plasmacytoma, but it includes the added criteria that neighboring sites of the tumor have been exposed. Extramedullary myeloma is a classification of myeloma characterized by tissue involvement outside the patient's bone marrow, including the muscles, lungs, or skin.

Glioma

Glioma is a type of tumor that starts in the glial cells in the brain. Glial cells are the cells in the central nervous system that are supportive and do not conduct electrical impulses. These types of cells are responsible for providing insulation and support for neurons by surrounding them. Gliomas are considered intra-axial brain tumors due to their tendency to develop within the brain substance and mingle with normal brain tissues. There are six different types of glial cells and several types of gliomas that can form in the central nervous system. Astrocytomas are tumors that begin in the astrocytes or connective tissue cells. Brain stem gliomas develop in the glial cells of the brain stem. Ependymomas are tumors that develop out of the cells responsible for lining the spinal cord and brain ventricles. Mixed gliomas are brain tumors that include more than one type of glial cell. Oligodendrogliomas are tumors that develop in the oligodendrocytes or glial cells of the cerebrum. Optic pathway gliomas are cancerous tumors that develop in the cells that make up the optic chiasm or nerve.
