Hi Alan. The first three answers are incorrect. Cancer cells develop a variety of adaptations that literally allow them to 'hide' from the immune surveillance system. If the immune system cannot 'see' the cancer cells, it cannot attack them.
Many cancers never develop because the immune system often successfully identifies and destroys new cancer cells (before the cancer cells develop 'immunity' to the immune system).
A great deal of research is being done in this area.
Best wishes.

Because cancer cells are just one's own mutated cells, so that the white blood cells don't usually recognize them as "enemy" cells- just as another part of the body.

i work at a cancer clinc---yes the body does not try to fight cancer cells because they are your own normal cells that have mutated----though there are thousands of scenarios and kinds of cancer cells---the body usually feeds this area, this is the cause of loss of weight.
