Aneuploidy - answer✔A condition in which cells have abnormal structures or numbers.
Benign Tumor Cells - answer✔A type of abnormal cell growth in which normal cells grow in the
wrong place or at the wrong time as a result of a problem with cellular regulation.
Cancer (malignancy) - answer✔A type of abnormal cell growth in which cellular regulation is
lost, resulting in new tissues that serve no useful function, are harmful to the function of
normal cells and organs, and can lead to death if left untreated.
carcinogenesis (oncogenesis, malignant transformation) - answer✔Cancer development w/
changing of a normal cell into a cancer cell.
Carcinogens - answer✔Substances that change the activity of a cell's genes so the cell becomes
a cancer cell.
Cellular Regulation - answer✔The genetic and physiologic processes that control cellular
growth, replication, differentiation, and function to maintain homeostasis.
Metastasis - answer✔The ability of cancer cells to invade and spread into other tissues and
organs.
Metastatic Tumors (secondary tumors) - answer✔Cancerous tumor cells that move from the
primary location by breaking off from the original group and establishing remote colonies.
Mitosis - answer✔Cell Division
Neoplasia - answer✔Any new or continued cell growth not needed for normal development or
replacement of dead and damaged tissues
oncogenes - answer✔Proto-oncogenes promoting cell growth that no longer respond to signals
from suppressor genes for cellular regulation.
Oncoviruses - answer✔viruses that are known to cause cancer
Primary Cancer Prevention - answer✔the use of strategies to prevent the actual occurrence of
cancer
Primary Tumor - answer✔The original cancer cells and tumor resulting from carcinogenesis
