crushing many pills changes their rate of absorption which might allow too much to be absorbed at one time(the surface area of the pill changes which increases dissolution and absorption and many have coatings** that ensure only so much is absorbed at any one time).

when the active ingredient is a cancer drug there may be the possibility that this could be fatal

Be certain to ask your doctor before cutting and certainly crushing any pills

**Some of these coatings make sure the drug is absorbed in one part of the GI tract vs another ie, one with a more or less acid pH than another like a stomach vs somewhere further down the GI tract
