In the study of cancer, researchers have used different types of cells, different environmental conditions, and different experimental designs. but, all researchers have arrived at the same conclusion. which conclusion is that?

Absence of Contact inhibition mechanism

Explanation:

Basically all the cancers cells are not able to arrest their cellular growth when they come in contact of each other.

This mechanism by which cells inhibit their growth /proliferation when they come in contact of other cells after forming a monolayer is called as Contact inhibition mechanism.

This mechanism exists is normal cell but is not found in cancer cell of all types irrespective of their cell types, environmental conditions, and different experimental designs

i think that the best answer would be c.

tell me if im wrong : )

b.
