How does chemotherapy target exactly your colon cancer? Does it kill off a lot of normal colon cells too?

1 doctor agrees

In brief: It doesnt

Chemo works by inhibiting/killing cells which grow faster than normal cells.
There are side effects because normal cells divide as a normal function, so yes, normal cells are affected too. The trick is to give enough to kill the bad cells, and not so much that the side effects are intolerable.
