cancer (CA)
general term for a group of diseases characterized by an abnormal, uncontrolled growth of cells
cancerous
pertaining to cancer
carcinogen
any cancer-causing substance or organism
differentiation
acquiring characteristics or functions different from that of the original cell
dysplasia
abnormal growth of tissue
in situ
in the original place or site without any expansion or spread
invasion
the direct migration and penetration of cancerous cells into neighboring tissues
lesion
a pathologic change in tissue resulting from disease or injury
malignant
tumor that invades surrounding tissue and may spread to other body parts; cancerous
metastasis
spread of disease from one part of the body to another
oncogenes
mutated forms of genes that cause normal cells to grow out of control and become cancer cells
oncogenic
causing or being suitable for the development of a tumor
recurrence
the return of cancer or disease
remission
lessening in severity of disease symptoms; the period of time when a cancer is responding to treatment or is under control
TNM staging
abbreviation for cancer classification based on characteristics of the tumors, nodal involvement, and extent of metastasis
tumor staging
the extent of spread of a cancer from its original site
adenocarcinoma
malignant neoplasm composed of glandular tissue
adenoma
benign neoplasm composed of glandular tissue
carcinoma (CA)
malignant neoplasm derived from epithelial tissue, chiefly glandular (adenocarcinoma) or squamous (squamous cell carcinoma)
fibroma
benign neoplasm of fibrous connective tissue
fibrosarcoma
malignant neoplasm of deep fibrous tissue
lipoma
benign neoplasm of adipose (fat) tissue
liposarcoma
malignant neoplasm of adipose (fat) tissue
malignant neoplasm
tumor that invades surrounding tissue and is usually capable of metastasizing; can be located in any organ or tissue in the body
melanoma
tumor characterized by a dark appearance; most commonly occurs in the skin or in the eye
neoplasm
tumor; abnormal growth of new tissue into a mass; can be benign or malignant
neuroma
tumor derived from nervous tissue
myeloma
tumor composed of cells derived from bone marrow
sarcoma
malignant neoplasm of connective tissue or nonepithelial tissue
basal cell carcinoma (BCC)
a cancer that begins in the lowest layer of the epidermis of the skin
Kaposi sarcoma
cancer of the skin and sometimes lymph codes that causes purplish-red patches on the skin; most commonly seen in patients with acquired immunodeficiency syndrome (AIDS)
melanoma
a malignant skin cancer that arises from the melanocytes in the epidermis, usually caused by exposure to ultraviolet (UV) radiation
squamous cell carcinoma (SCC)
a cancer that begins in the squamous cells located in the upper levels of the epidermis of the skin
chondrosarcoma
a large malignant tumor arising from cartilage cells
Ewing tumor; Ewing sarcoma
a malignant tumor found in bone or soft tissue
giant cell tumor
a tumor of the tendon sheath that can be either benign or malignant
leiomyoma
benign tumor of smooth (nonstriated) muscle
leiomyosarcoma
malignant tumor of smooth (nonstriated) muscle
liposarcoma
a malignant tumor of adipose (fat) tissue in deep soft tissue; occurs in the retroperitoneal tissues and the thigh
osteofibroma
benign lesion of bone consisting mainly of fairly dense, moderately cellular, fibrous connective tissue
osteosarcoma
fast-growing malignant type of bone cancer that develops in the bone-forming cells (osteoblasts); most common and most malignant of bone sarcomas
rhabdomyoma
benign tumor of striated (skeletal) muscle
rhabdomyosarcoma
a highly malignant tumor of striated (skeletal) muscle
astrocytoma
a tumor that arises from small, star-shaped cells (astrocytes) in the brain and spinal cord
glioma
cancer that arises from the glial cells of the nervous system
medulloblastoma
cancer that develops from the primitive nerve cells in the medullary tube and is usually located in the cerebellum
meningioma
benign and slow-growing tumor of the meninges
neuroblastoma
malignant tumor of embryonic nerve cells (neuroblasts); neuroblastomas frequently occur in infants and children, and 30% are associated with the adrenal glands
intraocular melanoma
a malignant cancer that forms in the tissues of the eye
retinoblastoma
a malignant ocular tumor of the retina that affects young children
multiple endocrine neoplasia (MEN)
a group of disorders characterized by functioning tumors in more than one endocrine gland
pheochromocytoma
a vascular tumor of the adrenal gland
pituitary adenoma
a benign tumor arising in the pituitary gland
Hodgkin disease
cancer of the immune system marked by the presence of Reed-Sternberg cells (large, transformed pathogenic cells derived from B lymphocytes)
