Cancer' is a broad spectrum with normal cell on one end and completely abnormal cell on the other end. The less differentiated a cancer cell is, the more severe form of disease it is.

For example. You might have a normal skin cell. It then divides incorrectly and it turns into a 'cancer cell' i.e one that's going to continue dividing and dividing without stopping going to form a tumour.

This very first cancer cell is almost identical to its parent skin cell. the only difference is in one bit of its DNA which now tells it to divide non-stop. It looks the same, it still does some of the work of a normal skin cell, only it divides wrong.

As it continues to divide, it passes on its genetic mistake, and due to its unstable (broken) DNA it is prone to creating increasingly dodgy cell offspring. (sorry if im speaking too simply!)

So anyway, as you go down the cellular family tree of this one cancer cell, the cells start to look and act worse and worse. Some might have two nucleii, some might start acting like a stomach cell and secrete acid, some might turn into hair cells. These are called poorly differentiated cells and indicate a very advanced cancer.

To summarise. Cancer cells start off as normal cells. The more they divide (the longer they remain unnoticed/untreated) the less they look like the cell of origin.
