Why can’t you just cut off cancer cells?

Question

I know there’s a reason, but I don’t know what it is.

Answer 1

Part of it is surgical shock that comes at a risk, while the ‘reward’ of such a surgery may involve not even getting rid of it, allowing it to grow back again.. I believe it’s similar to mold, since cancer can be as small as a single cell, what is seen may not be all there is.
