Suppressed immune surveillance lets malignant cells survive and proliferate

Evidence

Most of the time they don’t do enough damage for us to notice. You might lose a few cells, but you won’t notice it because we’ve got a lot of extra cells.” A healthy, vigilant immune system will attack and kill aberrant cells. But if the immune system has been damaged, as Levin speculated, a malignant cell stands a far greater chance of surviving and proliferating. — , Harr Jonathan - A Civil Action, 655
