Answer 1

Answer: (D)

Cancer is not contagious, but the cancerous cells are highly differentiated cells. Cancer is the result of a continuous, abnormal and relatively autonomous cell proliferation, which is due to the permanent alteration of some cells that gets transmitted to cell family. It is a disease caused by the loss of control over a cell’s reproduction capacity. Rather than dividing in a controlled and programmed manner, the cell continues to divide as a result detectable lump of tumor develops.
