Neoplasms Flashcards
Neoplasm
New Growth
Tumor
Swelling or neoplasm
Leukemia
Malignant disease of bone marrow Increase White Blood Cell Production
Hematoma
blood tumor, not cancerous a bruise
2 Classifications of Neoplasms
Appearance, Growth and tissue of origin
Benign
Confined and do not spread to other areas, noncancerous
Malignant
metastasize or spread to other areas, is cancerous
tissue of origin
named according to where it is found
Lipoma
fatty tumor
Neuroma
Nerve tumor
malignant neoplasm of skin/epith
carcinoma
benign tumor of skin/epith
adenoma
connective tissue
bone, muscle, fat
benign tumor of bone
osteoma
malignant neoplasm of bone
osteosarcoma
sarcoma
neoplasm from connective tissue spread quickly, highly malignant
all malignant
leukemias and lymphomas
factors of normal cell growth and function
genes, contact with other cells, growth promoting or growth inhibiting substance
benign Neoplasm growth
tumors retain some normal structure, function
Usually encapsulated easy to excise
Slower growing than malignant neoplasms
Tumors can push on nerves causing pain
Could cause over or under-secretion of hormones
Tumors in the brain could cause death
Malignant neoplasm
Do not have normal growth structure and function
Structure is haphazard and inconsistent
No differentiation and no specialized function
Not encapsulated; crab-shape appearance
Metastasized to distant sites
Very fast growing and needs a lot of nutrients & O2
angiogenesis occurs
angiogenesis
new growth of blood vessels
angiogenesis causes normal cells to be deprived and nutrients which causes
cachexia
cachexia
loses weight and appears thin, frail, and weak
hyperplasia
too much growth (normal cells)
