Characteristics of benign tumors |
(1) grow slowly (2) usually encapsulated (3) differentiated (4) DO NOT metastasize |
|
Characteristics of malignant tumors |
(1) multiply rapidly (2) invasive, infiltrate (3) undifferentiated (4) DO metastasize |
|
Carcinogenesis |
damages genetic material (DNA) |
|
What is anaplastic with regards to cells? |
DNA stops making normal codes that allow normal cells to continue differentiating |
|
What is apoptosis? |
When normal cells undergo death ( cancer cells lose this ability) |
|
Some chemical carcinogens? |
Hydrocarbons ( nicotine products, auto exhaust, dyes, asbestos, hormones) |
|
Oncogenes |
Pieces of normal DNA when mutated (via translation) -> makes normal cells into cancerous cells |
|
Histogenesis?? |
?? |
|
cancerous tumors -> cancinomas |
solid tumors derived from epithelial tissue ( skin, glands, digestive tract, urinary tract, reproductive organs) |
|
cancerous tumor -> sarcomas |
arise from connective tissue ( bone, muscle, cartilage, bone marrow, lymphatic system) |
|
cancerous tumor -> mixed-tissue tumors |
derived from tissue able to differentiate into either epithelial + connective tissue ( Will's tumor, skin, gland cells, cartilage, "germ cell" tumor) |
