|
The ? theory of cancer is that cancer cells continually form within the body but the immune system recognizes and destroys non-self cells. The ? of the immune system allows cancer cells to reproduce.
|
immune,
breakdown |
|
|
The ? theory is the theory that a pt has at least two predisposing factors that burden the immune system and give the pt a higher chance to develop cancer.

Promotion
|
|
|
The stage of Carcinogenesis wher morphologic and phenotypic changes in cells takes place is the ? period.
|
progression
|
|
|
The stage of Carcinogenesis when cells break away from the original group of cells is the ? stage and local ? can some times be seen under the skin in a line traveling to other parts of the body.
|
metastasis,
seeding |

contact
|
|
|
Normal cell characteristics- normal cell have ? adherence, this where they stick together.

|
apoptosis
